Example Embodiment

[0022] The present invention will be further described in detail below in conjunction with the drawings.

[0023] The auditory recognition sensitivity test method of the present invention includes the following steps:

[0024] a. Set the test parameters of the test tone. Usually the test tone is a pure tone. The test parameters include frequency value, loudness value, stimulation duration and stimulation interval time; where the frequency value is greater than or equal to 1 Hz, preferably 1 / 24 octave, The loudness value is greater than or equal to 1dB, preferably 2dB, the stimulus duration is less than 1000ms, preferably 300ms, and the stimulation interval time is customized according to the sensitivity of the subject.

[0025] In the actual operation, select the stimulus type as pure tone; the frequency value is 1 / 24 octave; the loudness value is 2dB; the stimulus duration is 300ms; the interval time needs to be selected according to the sensitivity of the subject; the test range is...

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...
