[0002] With the continuous development of science and technology, home appliances are becoming more and more intelligent, and users' experience of home appliances is also improving. For example, refrigerators will generate noise during use. If the noise is too loud, it will affect the user's experience of using the refrigerator. Therefore, before the refrigerator leaves the factory, the noise during the operation of the refrigerator will be tested according to the test method required by the refrigerator noise detection standard. If the test results meet the standard requirements, it means that the noise generated by the refrigerator is qualified. However, home appliances with qualified noise cannot meet the user's increasingly improved experience, so the noise of home appliances needs to be improved. Summary of the invention

[0019] The present application provides a noise evaluation method for household appliances, wherein the household appliances may be refrigerators, microwave ovens, range hoods and other household appliances, and the specific form of the household appliances is not limited herein. Figure 1 , Figure 1 FIG. 1 is a flow chart of an embodiment of a noise evaluation method for household appliances provided by the present application. Figure 1 As shown, the noise evaluation method includes the following steps:

[0020] Step 110: Acquire noise signals of multiple household electrical appliances.

[0021] The noise signal of a household appliance refers to the noise signal emitted by the household appliance collected from outside the household appliance when the noise generated during the operation of the household appliance is transmitted to the outside of the household appliance. For example, when a refrigerator is running, noise is generated when the fan, compressor, etc. are running. The noise signals detected by different devices are different, and the noise signals detected inside and outside the refrigerator are also different. In order to minimize the impact of noise on users, multiple noise signals from outside the refrigerator are obtained. The noise signals of multiple household appliances in this embodiment refer to the noise signals of different household appliances of the same type. For example, when the household appliance is a refrigerator, the noise signals of multiple refrigerators are obtained.

[0022] The noise signal can be obtained by collecting the noise signal of the home appliance through a sound sensor or a detection device provided with a sound sensor. When the detection device collects the noise signal of the home appliance, it can simulate the situation where a user stands in front of the home appliance and hears the noise signal. The detection device can be an artificial head. For example, when the home appliance is a refrigerator, the artificial head can be set at a height of 1.5m and 0.5m from the refrigerator to simulate the position where a person hears the noise of the refrigerator.

[0023] Step 120: Perform relative comparison on the noise signal to obtain a relative comparison result.

[0024] The noise signal may be a noise signal composed of noise signals of multiple household appliances, that is, a noise signal composed of noise signals of multiple household appliances, for example, the noise signal is: 1+2+3+..., and the sequence number represents the noise signals from different household appliances. Or the noise signal may be multiple noise signals of multiple household appliances, for example, the noise signal is 1, 2, 3,..., and the sequence number represents the noise signals from different household appliances. The obtained noise signals may be relatively compared, which may be a relative comparison of noise signals in different time periods in the noise signal; or any two noise signals from different household appliances may be obtained for relative comparison.

[0025] Step 130: Determine an evaluation result based on the relative comparison result.

[0026] The noise signals of multiple household appliances are relatively compared, and the noise evaluation results of the multiple household appliances are determined based on the relative comparison results of the noise signals. The evaluation results of this embodiment can be determined based on the relative comparison results of the noise signals and in combination with other factors. For example, the user's perception and tolerance of the noise of the household appliances can be combined.

[0027] The noise evaluation method for household appliances provided in the present application includes obtaining noise signals of multiple household appliances; performing relative comparison on the noise signals to obtain relative comparison results; and determining evaluation results based on the relative comparison results. In the above manner, the present application uses the relative comparison method to perform relative comparison on the noise signals of multiple household appliances, so that the noise evaluation results of multiple household appliances determined based on the relative comparison results are more consistent with the user's subjective feelings about the noise of household appliances, because the user's subjective comparison of the noise of multiple household appliances usually adopts relative comparison thinking, and subjectively cannot use an absolute method to compare the noise of multiple household appliances. Therefore, the present application can make the evaluation results more consistent with the user's subjective feelings, provide an improvement direction for the noise reduction of household appliances, and improve the user experience.

[0028] Optionally, the noise signal of this embodiment includes multiple noise signals from multiple different household electrical appliances. Step 120 performs a relative comparison on the noise signals to obtain a relative comparison result, which can be achieved by the following steps:

[0029] Step 121: sorting the multiple noise signals based on the evaluation parameter, and obtaining a sorting result which is a relative comparison result of the multiple noise signals.

[0030] It can be known that sound information has three elements, namely frequency, amplitude and timbre. Among them, the amplitude of the sound reflects the energy contained in the sound. The larger the amplitude of the sound, the greater the energy of the sound and the higher its volume; the smaller the amplitude of the sound, the smaller the energy of the sound and the lower its volume. The frequency of the sound reflects the different tones of the sound. The higher the frequency of the sound, the higher the pitch and the sharper the sound; the lower the frequency of the sound, the lower the pitch and the deeper the sound. The timbre of the sound reflects the unique quality of the sound emitted by each object. Among them, since the timbre reflects the unique quality of the sound emitted by each object, the evaluation parameter of this embodiment can be the volume and / or pitch of the noise signal.

[0031] This embodiment sorts multiple noise signals based on the evaluation parameters, and obtains the sorting result as a relative comparison result of the multiple noise signals. For example, the noise signals include a first noise signal, a second noise signal, and a third noise signal, and the first noise signal, the second noise signal, and the third noise signal come from different household appliances, and the evaluation parameters of any two noise signals are relatively compared, and the evaluation parameters of the first noise signal, the second noise signal, and the third noise signal are sorted, and finally the sorting result is used as the relative comparison result of the first noise signal, the second noise signal, and the third noise signal.

[0032] This embodiment sorts multiple noise signals based on evaluation parameters, and obtains a sorting result as a relative comparison result of the multiple noise signals, that is, by obtaining the relative comparison result of the noise evaluation parameters, a direction for improving the noise reduction of household appliances is provided through different evaluation parameters.

[0033] Optionally, when the evaluation parameter of the noise signal is the noise volume, the volumes of the multiple noise signals are relatively compared, and the volume ranking result is used as the relative comparison result of the multiple noise signals.

[0034] Optionally, see Figure 2 , Figure 2 is a flow chart of another embodiment of step 120 provided by the present application, such as Figure 2 As shown, step 120 can also be implemented by the following steps:

[0035] Step 122: Play the noise signal.

[0036] Playing a noise signal can be understood as playing a noise audio signal. Playing a noise signal simulates the situation of hearing the noise generated by home appliances when they are working.

[0037] Step 123: Obtain a relative comparison result of the noise signal.

[0038] The played noise signals are relatively compared to obtain relative comparison results of the noise signals, for example, a relative comparison is performed between the first noise signal heard and the second noise signal heard, or a relative comparison is performed between the first noise signal heard and the third noise signal heard.

[0039] The method of this embodiment includes playing a noise signal and obtaining a relative comparison result of the noise signal. In the above manner, playing the noise signal simulates the scene of hearing the noise generated when the home appliance is working, and the heard noise signals are relatively compared, so that the noise of the home appliance can be evaluated from the user's perspective, and improvement directions that meet the user's feelings can be proposed.

[0040] Optionally, in order to improve the credibility of the relative comparison result of the noise signals of the household appliances, the noise signals of this embodiment include the first noise signal and the second noise signal from different household appliances. Figure 3 , Figure 3 is a flowchart of another embodiment of step 120 provided by the present application, such as Figure 3 As shown, step 120 can also be implemented by the following steps:

[0041] Step 211: Perform audio splicing on the first noise signal and the second noise signal to form a spliced ​​audio signal.

[0042] The spliced ​​audio signal of this embodiment includes the first noise signal and the second noise signal from different household appliances. It can be understood that different time periods in the spliced ​​audio signal are the first noise signal and the second noise signal from different household appliances. Due to the limited memory of human beings, if the noise signal is played continuously, the objective evaluation of the noise signal cannot be maintained when the audio time of the noise signal is too long. In order to improve the credibility of the relative comparison result of the noise signals of household appliances, the first noise signal and the second noise signal are spliced ​​to form a spliced ​​audio signal.

[0043] Step 212: Play the spliced ​​audio signal.

[0044] Play the spliced ​​audio signal to simulate the noise generated by home appliances when they are working.

[0045] Step 213: Obtain a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal.

[0046] A relative comparison is performed on the first noise signal and the second noise signal in the played spliced ​​audio signal, and a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal is obtained.

[0047] For example, the noise signal includes a first noise signal, a second noise signal, a third noise signal, and a fourth noise signal from four household electrical appliances, and audio splicing is performed on any two of the noise signals, for example, the first noise signal and the second noise signal are audio spliced ​​to form a first spliced ​​audio signal, and the third noise signal and the fourth noise signal are audio spliced ​​to form a second spliced ​​audio signal. The first spliced ​​audio signal is played to obtain a relative comparison result between the first noise signal and the second noise signal in the first spliced ​​audio signal; the second spliced ​​audio signal is played to obtain a relative comparison result between the third noise signal and the fourth noise signal in the second spliced ​​audio signal.

[0048] This embodiment performs a relative comparison on the noise signal to obtain a relative comparison result, including audio splicing of the first noise signal and the second noise signal to form a spliced ​​audio signal, playing the spliced ​​audio signal, and obtaining a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal. Through the above method, only the first noise signal and the second noise signal need to be relatively compared, which is more in line with the subjective feelings of users when evaluating the noise of different home appliances, thereby improving the objectivity of the relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal, and further improving the credibility of the relative comparison result of the noise signals of home appliances.

[0049] Optionally, in order to further improve the credibility of the relative comparison evaluation result of the noise signals of the household appliances, the noise signals include a first noise signal and a second noise signal from different household appliances, and a buffer signal. Figure 4 , Figure 4 is a flowchart of another embodiment of step 120 provided by the present application, such as Figure 4 As shown, step 120 can also be implemented by the following steps:

[0050] Step 311: Obtain a buffered signal, and splice the buffered signal between the first noise signal and the second noise signal to form a spliced ​​audio signal.

[0051] The spliced ​​audio signal of this embodiment includes the first noise signal and the second noise signal from different household appliances, and the buffer signal. It can be understood that different time periods in the spliced ​​audio signal are the first noise signal, the second noise signal and the buffer signal from different household appliances. Due to the limited memory of human beings, if the noise signal is played continuously, the objective evaluation of the noise cannot be maintained when the audio time is too long. In order to improve the credibility of the relative comparison result of the noise signals of household appliances, this embodiment obtains the buffer signal and performs audio splicing on the first noise signal, the buffer signal and the second noise signal, wherein the buffer signal is located between the first noise signal and the second noise signal. Among them, the buffer signal can be a signal unrelated to the noise signal, which is used to distinguish the first noise signal from the second noise signal. For example, the buffer signal can be an audio signal without volume.

[0052] For example, when evaluating by machine, the buffer time can distinguish the first noise signal from the second noise signal. When evaluating by user, the buffer time can distinguish the first noise signal from the second noise signal and can also provide the user with time to think.

[0053] Step 312: Play the spliced ​​audio signal.

[0054] Play the spliced ​​audio signal to simulate the noise generated by home appliances when they are working.

[0055] Step 313: Obtain a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal.

[0056] A relative comparison is performed on the first noise signal and the second noise signal in the played spliced ​​audio signal, and a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal is obtained.

[0057] For example, the noise signal includes a first noise signal, a second noise signal, a third noise signal, and a fourth noise signal from four household appliances, and audio splicing is performed on any two of the noise signals. For example, the first noise signal and the second noise signal are audio spliced, and a 2s silent time is spliced ​​between the first noise signal and the second noise signal as a buffer signal to form a first spliced ​​audio signal. The third noise signal and the fourth noise signal are audio spliced, and a 2s silent time is spliced ​​between the third noise signal and the fourth noise signal as a buffer signal to form a second spliced ​​audio signal. When playing the first spliced ​​audio signal, after listening to the first noise signal, there is 2s of differentiation or thinking time, and then the second noise signal is listened to, and finally the relative comparison result between the first noise signal and the second noise signal in the first spliced ​​audio signal is obtained.

[0058] This embodiment performs a relative comparison on the noise signal to obtain a relative comparison result, including obtaining a buffer signal, splicing the buffer signal between the first noise signal and the second noise signal to form a spliced ​​audio signal, playing the spliced ​​audio signal, and obtaining a relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal. In the above manner, the first noise signal, the buffer signal, and the second noise signal are audio spliced ​​to form a spliced ​​audio signal. After playing the audio signal, only the first noise signal and the second noise signal need to be relatively compared, which is more in line with the user's subjective feelings when evaluating the noise of different home appliances, thereby improving the objectivity of the relative comparison result between the first noise signal and the second noise signal in the spliced ​​audio signal, and then improving the credibility of the relative comparison result of the noise signal of the home appliance; further, when the first noise signal and the second noise signal are relatively compared, a buffer signal for distinction or thinking is provided, thereby further improving the credibility of the relative comparison result of the noise signal of the home appliance.

[0059] Optionally, the relative comparison result includes a relative comparison evaluation result. When the user evaluates the spliced ​​audio signal, if the user believes that the subjective feeling of the first noise signal in the spliced ​​audio signal is better than the second noise signal, the relative comparison evaluation result is 2 points, if the user believes that the subjective feeling of the two groups of noise signals is similar, the relative comparison evaluation result is 1 point, and if the user believes that the second noise signal is better than the first noise signal, the relative comparison evaluation result is 0 point.

[0060] This application provides a household appliance noise evaluation system, see Figure 5 , Figure 5 is a structural diagram of an embodiment of a noise evaluation system for household appliances provided by the present application, such as Figure 5 As shown, the noise evaluation system 10 includes a detection mechanism 11 and a processor 12. The detection mechanism 11 and the processor 12 are connected in communication, and the detection mechanism is used to collect noise signals of multiple household appliances. The processor executes any one of the noise evaluation methods in the above-mentioned embodiments of the noise evaluation method for household appliances based on the acquired noise signals to determine the noise evaluation result of the household appliances. It can be understood that the detection mechanism 11 and the processor 12 are connected in communication, and the communication connection can be achieved through a connecting line or wirelessly. The specific process of the processor executing the noise evaluation method can be found in the above-mentioned embodiments of the noise evaluation method, which will not be repeated here.

[0061] The evaluation system provided by the present application is provided with a detection mechanism and a processor, wherein the detection mechanism and the processor are in communication connection, the detection mechanism is used to collect noise signals of multiple household appliances, and the processor determines the noise evaluation results of the household appliances based on the noise signals obtained and according to the noise evaluation method of the household appliances. Specifically, the evaluation method includes obtaining the noise signals of multiple household appliances; performing relative comparison on the noise signals to obtain relative comparison results; and determining the evaluation results based on the relative comparison results. In the above manner, the present application adopts the relative comparison method to perform relative comparison on the noise signals of multiple household appliances, so that the evaluation results determined based on the relative comparison results are more in line with the user's subjective feelings about the noise of the household appliances, because the user's subjective comparison of the noise of multiple household appliances is usually also based on relative comparison thinking, and subjectively it is impossible to use an absolute method to compare the noise of multiple household appliances. Therefore, the present application can make the evaluation results more in line with the user's subjective feelings, provide an improvement direction for the noise reduction of household appliances, and improve the user experience.

[0062] Optionally, the noise evaluation system further includes an artificial head 13, which is used to collect noise signals of household appliances. When the artificial head 13 collects noise signals of household appliances, it simulates the real feeling of a person standing in front of the household appliances. For example, when the household appliance is a refrigerator, the artificial head 13 is located at a height of 1.5m and a distance of 0.5m from the refrigerator, and collects noise signals for a period of time when the refrigerator is working.

[0063] In this embodiment, an artificial head is set up to collect noise signals of household appliances. A subjective evaluation of the noise of the household appliances can be made through high-fidelity audio recorded by the acoustic artificial head without the need to be at the site of use of the household appliances, and accurate data comparison of the noise of different household appliances can be achieved.

[0064] Optionally, the noise evaluation system further includes an evaluation mechanism 14, which is used to record user information, play noise signals, and record relative comparison evaluation results of noise signals of household appliances corresponding to the user information. It can be understood that the evaluation mechanism can be used to obtain the user's relative comparison results of the noise signal.

[0065] See also Figure 6 , Figure 6 is a schematic diagram of the structure of an embodiment of an evaluation mechanism provided by the present application, such as Figure 6As shown, the evaluation mechanism 14 is an evaluation mechanism designed based on MATLAB, and the evaluation mechanism 14 includes a user information module 141, a playback module 143, an audio signal selection module 142, a comparison evaluation result module 144, a confirmation module 145, a printing module 146 and a relative comparison rule module 147. Among them, the user information module 141 is used to record user information; the audio signal selection module 142 stores the spliced ​​audio signal; the playback module 143 is used to randomly play the spliced ​​audio signal that has not been played when the user clicks, and the spliced ​​audio signal is randomly played during the user's relative comparison process to avoid other factors from interfering with the user; the comparison evaluation result module 144 is used to record the user's relative comparison evaluation result of the currently played spliced ​​audio signal; the confirmation module 145 is used for the user to confirm the relative comparison evaluation result of the current spliced ​​audio signal; the printing module 146 is used to print the relative comparison evaluation result of the spliced ​​audio signal corresponding to the user. When the user uses the evaluation mechanism, the steps are as follows:

[0066] 1. User enters name

[0067] The user inputs the user's name in the user information module 141 , and different users generate different comparative evaluation result records.

[0068] 2. Click to load data

[0069] After clicking the audio signal selection module 142 to load data, a folder selection interface appears, and the folder path of the audio signal to be spliced ​​is selected. After selecting the path, the number of data that needs to be evaluated in the folder is prompted. In this process, MATLAB loads all the spliced ​​audio signal files in lossless sound quality format in the folder and sorts them randomly.

[0070] 3. Click to play the next set

[0071] Click the play module 143, and MATLAB plays a set of spliced ​​audio signals.

[0072] 4. Select the score

[0073] The relative comparison method is used for evaluation. If the user thinks that the first group of sounds in the played spliced ​​audio signal is subjectively better than the second group of sounds, select 2 points in the score column; if the user thinks that the two groups of sounds are subjectively similar, select 1 point in the score column; if the user thinks that the second group of sounds is better than the first group of sounds, select 0 points in the score column.

[0074] 5. Click to confirm the score

[0075] After selecting the score, the user clicks the confirmation module 145 to confirm the score to prevent the user from missing it. MATLAB records the score corresponding to the spliced ​​audio signal played this time.

[0076] 6. Repeated Scoring

[0077] Click the play module 143 to play the next group to continue comparison, and repeat the above steps until all the spliced ​​audio signals are played. After all the spliced ​​audio signals are played, the play module 143 prompts that all the audio signals to be spliced ​​are played.

[0078] 7. Export the scoring results

[0079] Click the print module 146 to export the evaluation record, and generate the evaluation record under the folder path selected in step 2, with different users in different tables.
