The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure.

[0059] In recent years, the variety of headphone styles has grown exponentially, with significant advancements in structure, functionality, and comfort. For example, open-back headphones are increasingly popular, offering greater comfort and safety than in-ear headphones, and are therefore gaining popularity among users and manufacturers. However, compared to traditional headphones like in-ear and headsets, open-back headphones exhibit more severe audio leakage, significantly impacting user privacy and security. Therefore, in-ear headphones require higher levels of audio leakage control.

[0060] However, there is no testing method for the degree of audio leakage suppression in related technologies, resulting in poor quality control of in-ear headphones and other earphones, and many earphones cannot meet users' privacy requirements.

[0061] Based on this, at least one embodiment of the present disclosure provides a leakage suppression test system, which can be used to test the leakage suppression of open-grade audio playback devices. The leakage suppression is used to characterize the audio leakage suppression capability of the audio playback device when worn on the human ear. In other words, it is used to characterize the degree of audio leakage.

[0062] Attachment Figure 1 The architecture diagram of the test system is shown as an example. Figure 1 The architecture of the test system is introduced in detail; it should be understood that the attached Figure 1 The illustrated structure does not constitute an architectural limitation for the test system.

[0063] The system may include an artificial ear 100, at least one sound collecting device (e.g., an attached Figure 1 The sound receiving devices 301, 302, 303) and the test equipment (attached Figure 1 not shown).

[0064] In the test system, the artificial ear 100 and the at least one sound collecting device are both in a standard test environment, such as an anechoic chamber.

[0065] The artificial ear 100 is used to wear the audio playback device to be tested and collect audio parameters. For example, the artificial ear 100 can simulate the shape of a real human ear to achieve the same wearing state as a real human ear. Figure 1 The artificial head 200 is not shown in the figure, and the artificial torso, artificial head 200, and artificial ear 100 are installed according to the relative positions of a real human torso, head, and ear. For example, the audio parameters collected by the artificial ear 100 can represent the parameters of the audio entering the ear when the audio playback device is worn on a real human ear.

[0066] The sound receiving device may be a free-field microphone unit or other sound receiving device that meets WS2F (Working Standard Free-Field) requirements, i.e., a 1 / 2-inch free-field working standard microphone with a sensitivity greater than -36dBV and a signal-to-noise ratio greater than 70dB. The relative position between the at least one sound receiving device and the artificial ear 100 meets the test requirements. The relative position meeting the test requirements may include at least one of the following:

[0067] The distance between each of the at least one sound collecting device and the artificial ear 100 is equal, for example, r.

[0068] The at least one sound collecting device is respectively located in different directions of the artificial ear 100. For example, the at least one sound collecting device is evenly distributed in different directions of the audio playing device. Figure 1 Taking the system architecture shown as an example, the at least one sound collecting device includes three sound collecting devices 301, 302, and 303, wherein the first sound collecting device 302 is arranged in the direction of the simulated human ear opening of the artificial ear 100, the second sound collecting device 301 is arranged in the direction of the simulated human ear opening of the artificial ear rotated 45° clockwise, and the third sound collecting device 303 is arranged in the direction of the simulated human ear opening of the artificial ear rotated 45° counterclockwise.

[0069] Each of the at least one sound collecting device is directed toward the artificial ear, for example, toward the entrance of the ear canal of the artificial ear.

[0070] Preferably, the at least one sound collecting device and the artificial ear satisfy the above three conditions at the same time, and then these sound collecting devices are located on an arc with the artificial ear as the center. Figure 1 In the structure shown, the direction of the simulated head is 0°, and the direction obtained by rotating the head clockwise by an angle of α is α. Figure 1 The directions of the three sound collecting devices 301, 302 and 303 are respectively in the 45° direction, the 90° direction and the 135° direction of the arc with the artificial ear as the center and r as the radius.

[0071] The test device is respectively connected to the artificial ear and the at least one sound receiving device, and is used to obtain the audio parameters detected by the artificial ear and the audio parameters detected by each sound receiving device, and measure the leakage suppression amount of the audio playback device to be tested based on the audio parameters detected by the artificial ear and the audio parameters detected by each sound receiving device.

[0072] The test system may also include an acoustic calibrator for acoustically calibrating the artificial ear, sound receiving equipment, and the like to meet test standards. For example, the acoustic calibrator may be connected to the test equipment to interact with the test equipment (e.g., being controlled by the test equipment and transmitting test results to the test equipment).

[0073] The leakage suppression test system provided by the disclosed embodiments enables standardized testing of the leakage suppression of audio playback devices such as open-back headphones, thereby providing a guarantee and foundation for improving the quality control of audio playback devices. The structure and parameters of the test system are recommended as industry standards.

[0074] At least one embodiment of the present disclosure provides a method for testing leakage suppression. This method can be applied, for example, to the test equipment of the aforementioned test system, or to other terminal devices. It should be understood that if the method is performed using the test equipment of the aforementioned test system, the artificial ear and the at least one sound pickup device can be acoustically calibrated before execution to meet the test standard, and the relative relationship between the artificial ear and each sound pickup device can be calibrated.

[0075] For example, an acoustic calibrator can be used to acoustically calibrate the artificial ear and each sound receiving device. The following describes the specific calibration process using the artificial ear as an example: First, connect the signal input and output of the acoustic calibrator to the artificial ear. Next, set the calibration frequency and amplitude via the acoustic calibrator's control panel. Next, initiate calibration via the acoustic calibrator's control panel, at which point the output of the acoustic calibrator will emit a specific constant sound pressure signal. Finally, the acoustic calibrator's control panel displays the artificial ear's response to the sound signal at the input. Based on this response, the artificial ear's performance is calibrated until the artificial ear meets the test standard.

[0076] For example, an acoustic calibrator connected to the test equipment can be used to acoustically calibrate the artificial ear and each sound receiving device. The specific calibration process is described using the artificial ear as an example: First, with the signal input and output of the acoustic calibrator connected to the artificial ear, the test equipment controls the acoustic calibrator to set the calibration frequency and amplitude. Next, the test equipment controls the acoustic calibrator's output to emit a specific constant sound pressure signal, and acquires and displays the artificial ear's response to the sound signal, as detected by the acoustic calibrator's input. Based on this response, the test equipment calibrates the performance of the artificial ear until the artificial ear meets the test standard.

[0077] Please refer to the attached Figure 2 , which exemplarily shows the process of the method, including steps S201 to S203.

[0078] In step S201, when the audio playback device is worn on the artificial ear and a test audio is played, a first sound parameter detected by the artificial ear is obtained.

[0079] It can be seen from the above test system that when the artificial ear is in a standard test environment, the audio playback device worn on the artificial ear is also in a standard test environment.

[0080] The audio playback device may be an open-ear headset to be tested, etc. The test audio may be test material of male and female students, etc. The first sound parameter may be a spectrally weighted total sound pressure level, such as A-weighted total sound pressure level, B-weighted total sound pressure level, C-weighted total sound pressure level, Z-weighted total sound pressure level, etc. Spectral weighting is a standard weighting curve used in audio measurements. A-weighting is a widely used single-valued noise evaluation metric, simulating the human ear's response to a 40-degree pure tone. B-weighting, commonly used in environmental noise measurements, weights the sound signal at higher frequencies and simulates the human ear's response to a 70-degree pure tone. C-weighting, also commonly used in environmental noise measurements, weights the sound signal at lower frequencies and simulates the response to a 100-degree pure tone. Z-weighting, sometimes called linear weighting, indicates no weighting across the entire frequency range and is primarily used in aircraft noise assessment. Generally, A-weighting is used for noise measurements between 24 and 55 degrees; B-weighting is used for noise measurements between 55 and 85 degrees; and C-weighting is used for noise measurements above 85 degrees.

[0081] For example, for the above-mentioned test system, the audio playback device to be tested can be pre-placed on the artificial ear and controlled to play the test audio. Preferably, the test audio is played using standard playback parameters, such as the maximum volume of the device to be played. In this step, the first sound parameter detected by the artificial ear can be obtained while the audio playback device is worn on the artificial ear and the test audio is played using the standard playback parameters.

[0082] It should be understood that a one-way or two-way control connection may also be established between the audio playback device to be tested and the test device, so that the test device can control the audio playback of the audio playback device after the audio playback device is worn on the artificial ear.

[0083] In step S202, when the audio playback device is worn on an artificial ear or a human ear and plays the test audio, a second sound parameter detected by at least one sound receiving device is obtained, wherein the relative position between the at least one sound receiving device and the audio playback device meets the test requirements.

[0084] From the above test system, it can be seen that the artificial ear and at least one sound receiving device are in a standard test environment, and the audio playback device worn on the artificial ear, the human ear, and the audio playback device worn on the human ear are also in a standard test environment.

[0085] With the above-mentioned test system, it can be known that if the relative position between the at least one sound receiving device and the artificial ear meets the test requirements, then the relative position between the at least one sound receiving device and the audio playback device worn on the artificial ear also meets the test requirements. The relative positions required by the above test can include at least one of the following: the distance between each of the at least one sound receiving device and the audio playback device is equal; the at least one sound receiving device is located in different directions of the audio playback device; each of the at least one sound receiving device is facing the audio playback device. Each of the above relative positions has been introduced in detail in the test system and will not be repeated here.

[0086] The second sound parameter may be a spectrally weighted total sound pressure level, such as A-weighted total sound pressure level, B-weighted total sound pressure level, C-weighted total sound pressure level, or Z-weighted total sound pressure level. Spectral weighting is a standard weighting curve used in audio measurements. A-weighting is a widely used single-value noise evaluation metric that simulates the human ear's response to a 40-degree pure tone. B-weighting, commonly used in environmental noise measurements, weights sound signals in the higher frequency range and simulates the human ear's response to a 70-degree pure tone. C-weighting, also commonly used in environmental noise measurements, weights sound signals in the lower frequency range and simulates the response to a 100-degree pure tone. Z-weighting, sometimes also called linear weighting, indicates no weighting across the entire frequency range and is primarily used in aircraft noise assessments. Generally speaking, A weighting is used for noise measurements between 24 and 55 cubic meters; B weighting is used for noise measurements between 55 and 85 cubic meters; and C weighting is used for noise measurements above 85 cubic meters.

[0087] It should be understood that the second sound parameter and the first sound parameter are parameters of the same type.

[0088] It should be understood that each sound collecting device may detect the second sound parameter simultaneously or sequentially.

[0089] For example, this step can be performed simultaneously with step S201. This ensures that the first audio parameter detected by the artificial ear in step S201 and the second audio parameter detected by the sound receiving device in step S202 are parameters collected for the audio being played simultaneously, making it more reasonable to use them to determine the amount of leakage suppression. This approach is referred to as direct detection mode.

[0090] For example, before or after executing step S201, a person can be made to enter a standard test environment and have the human ear replace the artificial ear, that is, the human ear maintains the same position, angle, etc. as the artificial ear, and after the audio playback device to be tested is worn on the human ear and the test audio is played, the second sound parameter detected by at least one sound receiving device is obtained. Preferably, a male and a female of appropriate age (for example, 23 to 60 years old) can be selected, and after wearing the audio playback device respectively, the second sound parameter is detected in the above manner, and the second sound parameters obtained by the two are averaged (that is, the two second sound parameters obtained by each sound receiving device for two people are averaged) as the final measurement value. This makes the second sound parameter detected by the sound receiving device more accurate when it is for the scenario where the audio playback device is worn on a real human ear. This method can be called a replacement detection mode.

[0091] Preferably, in this step, when the audio playback device is worn on an artificial ear or a human ear and the test audio is played with the standard playback parameters, a second sound parameter detected by at least one sound receiving device is obtained, for example, the standard playback parameters include the maximum volume of the device to be played, etc.

[0092] In step S203, a leakage suppression amount of the audio playback device is determined according to the first sound parameter and a second sound parameter detected by the at least one sound receiving device.

[0093] Exemplarily, the difference between the first sound parameter and the average sound parameter is determined as the leakage suppression amount of the audio playback device, wherein the average sound parameter is the average value of the second sound parameter detected by the at least one sound receiving device, such as the arithmetic average or weighted average. Figure 1 Taking the architecture shown as an example, the A-weighted total sound pressure level detected by the artificial ear is L AH The A-weighted total sound pressure level detected by the sound receiving device 301 is L A45 The A-weighted total sound pressure level detected by the sound receiving device 302 is L A90 The A-weighted total sound pressure level detected by the sound receiving device 303 is L A135 ; You can first A45 , L A90 , L A135 Average to get L A0 , and the leakage suppression amount L is calculated according to the following formula:

[0094] L=L AH -L A0

[0095] In addition, the leakage suppression level of the audio playback device can also be determined based on the leakage suppression amount of the audio playback device. Optionally, the leakage suppression level of the audio playback device can be determined based on the leakage suppression amount of the audio playback device and at least one leakage suppression level threshold; wherein the leakage suppression level threshold for each leakage suppression level can be a leakage level lower limit, that is, if the leakage suppression amount is higher than the leakage suppression level threshold of a certain level, the leakage suppression level is that level; if the leakage suppression amount is higher than the leakage suppression level threshold of multiple levels, the leakage suppression level is the highest level among the aforementioned multiple levels.

[0096] For example, the leakage suppression level of the audio playback device may include a standard level and an enhanced level. The leakage threshold corresponding to the standard level is a first threshold, and the leakage threshold corresponding to the enhanced level is a second threshold. Therefore, if the leakage suppression level of the audio playback device is not less than the first threshold and less than the second threshold, the leakage suppression level of the audio playback device may be determined to be a standard level; and if the leakage suppression level of the audio playback device is not less than the second threshold, the leakage suppression level of the audio playback device may be determined to be an enhanced level. For example, if both the first sound parameter and the second sound parameter are A-meter weighted total sound pressure levels, the first threshold may be 30dB, and the second threshold may be 38dB.

[0097] The leakage suppression amount testing method provided in the embodiment of the present disclosure simulates the actual usage scenario of the audio playback device by wearing the audio playback device on an artificial ear or ear and playing test audio; and obtains the sound parameters detected by the artificial ear and the sound parameters detected by a pre-set sound receiving device that maintains a specific relative position with the audio playback device in this scenario, so as to obtain the part of the audio played by the audio playback device that enters the user's ear and the leakage part; and also measures the relative relationship between the above two parts of audio (i.e., the part of the audio played by the audio playback device that enters the user's ear and the leakage part) by configuring the leakage suppression amount, so as to characterize the leakage suppression degree of the audio playback device in the actual usage scenario with objective indicators, and can make the leakage suppression degree of audio playback devices such as open headphones able to be graded through a series of standards for leakage suppression amount, thereby improving the quality control of audio playback devices such as open headphones and improving the user experience.
