The present application relates to the field of sound field measurement of medical ultrasonic diagnostic equipment, and particularly relates to a sound mask for limiting square area sound power measurement and a preparation method thereof. The sound mask comprises: a first absorbing layer, a reflecting layer, an intermediate layer and a second absorbing layer which are sequentially stacked from top to bottom; the reflecting layer is located at the central region of the first absorbing layer, the intermediate layer and the second absorbing layer, and a square sound transmission hole penetrating through the thickness of the reflecting layer is formed on the reflecting layer; the first absorbing layer, the reflecting layer, the intermediate layer and the second absorbing layer are tightly adhered through a pouring process to form an integral plate structure. The present application reasonably arranges the mask structure of the sound mask by establishing a theoretical model of sound wave vertical incidence multi-layer medium, so that the sound beam can be constrained, and the performance of the sound mask can strictly meet the technical requirements of the industry standard YY / T1084-2015.

The utility model discloses tinnitus treatment equipment based on red light, low-frequency electrotherapy and bone conduction, and relates to the technical field of medical auxiliary instruments. Comprising a connecting piece, a control bin and an auxiliary bin, the control bin and the auxiliary bin are located at the two ends of the connecting piece respectively, ear hooks and bone conduction earphone vibrators located at the tail ends of the ear hooks are arranged on the front sides of the control bin and the auxiliary bin, red light physiotherapy assemblies are installed on the control bin and the auxiliary bin, and an electrode physiotherapy assembly is installed on the auxiliary bin. According to the equipment, when the electrode tip is plugged into the ear canal for low-frequency electrotherapy, the electrode tip can emit red light to irradiate the interior of the ear canal, and sound can be shielded in a bone conduction mode under the condition that the ear canal is blocked by the electrode tip, so that the influence of tinnitus on a patient is reduced; the device is very humanized in design, convenient to use and remarkable in treatment effect.

A method performed by an electronic apparatus, an electronic apparatus and a storage medium, which involves the field of artificial intelligence are provided. The method includes obtaining target sound masks of a target in a first video at respective moments, based on image-related information of the target, a first audio signal corresponding to the first video, and direction information of the first audio signal, and obtaining a second audio signal in which a sound related to the target is excluded, based on the target sound masks of the target at the respective moments and the first audio signal.

The application provides an oil fume exhaustor abnormal sound masking method and system based on an audio injection method, which is applied to an oil fume exhaustor control system and comprises the following steps: acquiring audio data of the oil fume exhaustor during operation; judging whether the oil fume exhaustor has abnormal sound during operation based on a comparison result of the audio data and preset audio data in a target dimension; the target dimension comprises a single frequency peak value difference, a frequency band deviation and an overall sound pressure level difference; if the oil fume exhaustor has abnormal sound, performing parameter optimization on parameters of a preset control sound based on the comparison result and a annoyance degree prediction model to obtain an optimized control sound; the parameters of the preset control sound comprise a frequency component, a frequency band range and a sound pressure level; and masking the abnormal sound of the oil fume exhaustor during operation based on the optimized control sound. The application alleviates the technical problem that the abnormal sound during actual operation cannot be effectively improved in the prior art.

A reminding method, system, and apparatus, a vehicle, a computer-readable storage medium, and a computer program product, which relate to the field of intelligent vehicles. According to the reminding method, a masking result of a sound masking system on a target sound at a sound masking location is determined, and the masking result is displayed to a user, so that user confidence in using the sound masking system can be improved. The reminding method further provides a plurality of modes for receiving user instructions and a plurality of modes for presenting reminder information to the user, so that various possible situations can be promptly and effectively fed back to the user, thereby improving user confidence in using the sound masking system, and further improving the usability of the sound masking system.

The embodiment of the invention provides a method executed by electronic equipment, the electronic equipment and a storage medium, and relates to the field of artificial intelligence. The method comprises the following steps: obtaining a target sound mask of a target at each moment based on image-related information of the target in a first video, a first audio signal corresponding to the first video and direction information of the first audio signal; and based on the target sound mask of the target at each moment and the first audio signal, a second audio signal is obtained, and the second audio signal does not include sound related to the target. Optionally, the method performed by the electronic device may be performed using an artificial intelligence model.

The invention discloses an audio playback method and device and a computer readable storage medium, the audio playback method is applied to an audio playback system, and the audio playback system comprises an intelligent musical instrument and an open earphone; the method comprises an intelligent musical instrument and an open earphone. The audio playback method comprises the following steps: the intelligent musical instrument generates an audio signal according to a pressure signal, and sends the audio signal to the open earphone; the open earphone plays the audio signal, and analyzes the main frequency band of sound leakage of the open earphone; and the intelligent musical instrument outputs a sound masking signal strongly related to the audio signal according to the sound leakage main frequency band. The intelligent musical instrument and the open type earphone work cooperatively, the loudspeaker of the intelligent musical instrument compensates for the deficiency of the earphone in the aspect of low frequency, and the open type earphone compensates for the problem of insufficient details of high-frequency playback of the intelligent musical instrument, thereby effectively making up the advantages and disadvantages of the two products, and ensuring high-fidelity output and spatial perception of audio.
