Hearing, or auditory perception, is the ability to perceive sounds by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. The academic field concerned with hearing is auditory science.

Motor abnormal sound intelligent identification method based on time-frequency characteristic and hearing adaptation

The invention relates to a motor abnormal sound intelligent identification method based on time-frequency characteristics and hearing adaptation, and belongs to the technical field of motor fault detection. The method comprises the steps that motor operation sound signals are collected in real time through a multi-azimuth sound signal collection array, and signal preprocessing and dynamic framing processing are carried out; a time-frequency spectrum is generated through short-time sliding window time-frequency conversion, a normal operation sound auditory baseline is established in combination with an auditory perception adaptive dynamic weighting technology, and hierarchical weighting processing is performed on the time-frequency spectrum to generate fused time-frequency weighted features; a time-frequency weighted feature enhanced residual network model is constructed, and abnormal feature extraction and recognition are realized through a cross-dimension fusion mechanism, a fault feature transfer learning mechanism and a fault feature attention mechanism; and a working condition dynamic adaptive reasoning mechanism and a hierarchical linkage alarm system are adopted to complete state recognition and alarm response. The method effectively improves the accuracy and real-time performance of motor abnormal sound recognition, and is suitable for motor state monitoring in a complex industrial environment.

Music rhythm atmosphere lamp control method, device, equipment and medium

The embodiment of the invention provides a music rhythm atmosphere lamp control method and device, equipment and a medium, and relates to the technical field of vehicles. The method comprises the following steps: collecting currently played audio stream data, and converting the audio stream data into corresponding frequency domain signal data; performing auditory perception correction processing on the frequency domain signal data to obtain a corresponding perception loudness value; converting the perception loudness value into a corresponding brightness control level based on a dynamic mapping function; and outputting and controlling the brightness of the atmosphere lamp based on the brightness control level. The method provided by the invention effectively solves the problem that the mode of controlling the atmosphere lamp based on the physical amplitude of music rhythm is not matched with human body perception in the prior art, so that the user experience is relatively poor.

Multi-channel and multi-mode audiometer and method

Enhanced audiometry methods and instruments to provide assessments of the nature and / or extent of a subject's hearing loss or impairments. Embodiments include applying at least first and second different test electrical stimulations to a subject, wherein the first and second test electrical stimulations are configured to stimulate hearing perception in the subject and are different. An identification of one or more characteristics of the perceived hearing produced by the at least first and second test electrical stimulations, such as an origin location of the perceived hearing, is received from the subject, and recorded in association with the at least first and second test electrical stimulations. Clinicians may improve the efficacy of treatments for the hearing impairments based on the recorded information.

Earphone loss post virtual audio experience maintenance method and system based on generative adversarial network

The application provides a headphone loss-based virtual audio experience maintenance method and system based on a generative adversarial network, and relates to the technical field of virtual audio experience reconstruction. After a headphone loss event is triggered, a set of wearing state recording segments containing an ear canal audio response segment and an environmental reference audio segment stored before loss is obtained; the ear canal audio response segment is subjected to ear canal impulse response deconvolution processing to obtain a personalized ear canal impulse response; the ear canal impulse response and the environmental reference audio segment are input into a generative adversarial network to generate a virtual microphone pickup signal on the headphone loss side, and are fused with a real-time microphone signal on the reserved side into a binaural virtual sound field synthesizer to obtain a compensation audio signal to be played by a loudspeaker on the loss side, which is emitted by a loudspeaker on the reserved side to reconstruct a binaural hearing perception state in the ear canal of a listener before loss, high-fidelity virtual audio reconstruction is achieved, and the continuity of binaural stereo experience after headphone loss is effectively maintained.

Intelligent service robot system integrated with voice recognition

The invention relates to the technical field of intelligent robot auditory perception and voice interaction, in particular to an intelligent service robot system integrated with voice recognition. The system comprises a multi-dimensional data acquisition module, a dynamic simulation processing module and a signal coupling judgment module. The system constructs standard semantic features by synchronously acquiring acoustic signals and kinematic telemetry data; the core of the method is that acoustic channel distortion simulation is carried out on standard features in combination with a motion state, theoretical distortion features are generated, and the similarity between the theoretical distortion features and real signals is calculated; if the similarity exceeds a threshold value, recovering the instruction, otherwise, performing noise filtering; according to the method, the transformation from passive noise reduction to active simulation verification based on a physical model is realized, the problem of non-stationary noise interference generated by robot motion is solved, and the interaction robustness under extreme working conditions is remarkably improved.
