Problems solved by technology

Human beings have very different perceptions of single-frequency signals or narrow-band signals such as pure tones and wide-band signals such as speech. Therefore, compensation based on pure-tone test results often does not achieve good results when applied to speech in daily life.

Abstract

The invention provides a method and device for calculating sound compensation parameters as well as a sound compensation system. The device for calculating the sound compensation parameters comprises a perception loudness calculating unit, a frequency point compensation grain calculating unit and a band compensation grain calculating unit, wherein the perception loudness calculating unit is used for calculating the perception loudness of a user to an appointed test voice under the appointed strength; the frequency point compensation grain calculating unit is used for determining a frequency point in the compensation parameters according to the comparison between the perception loudness of the user and the perception loudness of a normal person and calculating a compensation grain on the determined frequency point under the pre-set strength; and the band compensation grain calculating unit is used for expanding the calculated compensation grain on the frequency point to obtain the compensation grain aiming at the user and each pre-set strength of a whole band, and taking the expanded compensation grain as the sound compensation parameters. According to the invention, by using the compensation parameters customized aiming at the user to carry out the compensation, the perception ability and communication ability of the user are improved. The method and device for calculating the sound compensation parameters as well as the sound compensation system are suitable for hearing-aids, televisions, cell phones, music players and the like.

Description

technical field [0001] The present invention mainly relates to the fields of audiology and perceptual acoustics, more specifically, a method and system for speech auditory measurement and compensation. The use of speech signals for auditory measurement allows users to understand their own hearing acuity, hearing loss and misrecognition tendency for speech signals. By compensating the input sound with compensation parameters customized for users, the user's ability to hear and distinguish is improved. Communication skills. The invention is applicable to hearing devices with sound input and output, including but not limited to hearing aids, televisions, cell phones, music players, etc. Background technique [0002] With the development of society, especially China, has entered the aging society, the elderly population is increasing rapidly, and more and more elderly people have different hearing impairment problems. In addition, there are still many groups of different ages ...
