Hearing recognition sensitivity testing method

Abstract

The invention discloses a hearing recognition sensitivity testing method. The method comprises the steps of a, setting testing parameters of a tested sound, wherein the testing parameters comprises a frequency value, a loudness value, stimulus time-history and stimulus interval time; b, determining a testing sequence of the tested sound; c, giving the tested sound, and conducting a test, wherein the frequency value is bigger than or equal to 1 Hz, the loudness value is bigger than equal to 1 dB, and the stimulus time-history is smaller than 1000 ms. In the hearing recognition sensitivity testing method, a digital technology is utilized to avoid inaccuracy of manual control operation, so that the tested sound is compared and tested on a lot of frequencies and loudness, a the situation that the stimulus time-history is too long can be avoided, the number of hair cells (bandwidth) participating in excitement is effectively controlled, a threshold value error caused when the stimulus of inner ear hair cells corresponding to a tested frequency point is too long is avoided, the frequency recognition ability, the loudness recognition ability and the time recognition ability of a testee are quickly detected, the accuracy of detection is improved, the obtained testing structure comprises a lot of detail information, and a more complete basis is provided for diagnosis of diseases.

Description

technical field [0001] The invention belongs to an audiology test method, in particular to an auditory recognition sensitivity test method based on pure tone audiometry. Background technique [0002] Pure tone audiometry is a very popular audiometric test method, used to test the hearing sensitivity of the subject, reflecting the hearing level of the smallest sound of each frequency that the subject can hear in a quiet environment, and can be used for hearing The degree of damage and the nature of deafness are judged. The frequencies usually referred to only refer to 0.125, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6 and 8kHz, so the pure tone audiometry only reflects the sensitivity of the tested frequency. However, the intermediate frequency is often ignored, and it is in these ignored data that very important details are hidden, which is of great significance for the differential diagnosis of clinical diseases and auditory rehabilitation. In addition, the stimulation time course and s...

Problems solved by technology

[0004] The auditory recognition sensitivity test method is not only applicable to tinnitus inspection and tinnitus rehabilitation, but also can be extended to hearing rehabilitation fields such as hearing aid fitting. The hearing status of the user greatly improves the satisfaction with the use of hearing aids. At present, the satisfaction with the use of hearing aids is less than 30%.
