Problems solved by technology

[0003] However, the single-frequency signal test cannot accurately reflect the hearing condition of the human ear near this frequency point, which will cause the hearing curve test to be inaccurate, that is to say, the hearing curve is different from the real hearing condition of the tested person, thus affecting Subsequent applications such as hearing aid adaptation of the hearing curve cannot ensure the best hearing compensation effect for the hearing-impaired

Embodiment Construction

[0112] The following is attached Figure 1-10 The application is described in further detail.

[0113] The present application discloses a method for generating a hearing test signal. Such as figure 1 As shown, a method for generating a hearing test signal, comprising:

[0114] S1, generating a filter for setting subbands;

[0115] S2, generating Gaussian white noise with different sound pressure levels;

[0116] S3, passing the Gaussian white noise through filters of different subbands at the same time to generate a set hearing test signal;

[0117] S4. Store the hearing test signal.

[0118] In this embodiment, in order to improve the hearing compensation effect of the hearing-impaired person and improve the efficiency of the test, as figure 2 As shown, S1 specifically includes:

[0119] S11, dividing the sound signal that the human ear can perceive into multiple critical bands according to the resonance frequency of the human ear;

[0120] S12, merging the pluralit...

Abstract

The invention relates to a hearing test signal generation method, a hearing test method, a storage medium and equipment. The method comprises the steps of generating a filter for setting a sub-band; generating gaussian white noise with different sound pressure levels; enabling the Gaussian white noise to pass through filters of different sub-bands at the same time, and generating a set hearing test signal; and storing the hearing test signal. The method has the advantages that the difference between the hearing curve of the tested person and the real hearing condition is effectively reduced, and then the hearing compensation effect of the hearing impaired person is improved.

Description

technical field [0001] The present application relates to the field of hearing test technology, and in particular to a method for generating a hearing test signal, a hearing test method, a storage medium and equipment. Background technique [0002] The human ear perceives sound signals of different frequencies differently. When performing a hearing test, usually single-frequency signals of different sound pressure levels are played to the subject to listen to, and according to the listening test results, the subject's perception of different frequency sound signals is obtained, that is, the hearing curve. As disclosed in "Traunmüller, H. (1990). "Analytical expressions for thetonotopic sensory scale". The Journal of the Acoustical Society of America88: 97–91.", it uses sine waves at specific frequencies to obtain different sound pressures For single-frequency signals, the frequency division usually adopts the octave method, the low-frequency band is dense, and the high-freq...
