Frequency recognition testing method

Abstract

The invention discloses a frequency recognition testing method. The method includes the steps that a, sound is subjected to band allocation; b, a main frequency is determined from the bands for testing; c, sound of three adjacent frequencies including the main frequency is determined as stimulation sound, and auditory thresholds of the three frequencies are measured; d, testing sound is given sequentially, and testees make a judgment; e, the frequency interval is gradually reduced till the testees cannot distinguish the sound, and the minimal recognition bandwidth can be determined. The minimal frequency recognition range of the testees can be tested, frequency value selection in auditory sense recognition sensitivity testing is promoted, the workload of clinical hearing function check is reduced, and meanwhile the sensitivity degree of the testees on the frequency of sound stimulation is measured. The frequency recognition testing method has a great effect on diagnosis and treatment on tinnitus, epicophosis and dizziness and has great significance on the aspect of an audio output device, the auditory sense is effectively protected, hearing damage is avoided, and the satisfaction and comfort of popular headphone use are improved.

Description

technical field [0001] The invention belongs to an audiology test method, in particular to a frequency recognition test method. 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. It can be seen that the conventional pure tone audiometry method has begun to show short...

Problems solved by technology

[0003] The auditory recognition sensitivity test is different from the conventional pure tone audiometry. The frequency accuracy selected is very high. In order to reflect more detailed information and obtain very accurate and complete test results, it is usually simply based on the degree of cooperation of the subjects. 1 / 12 or 1 / 24 and other octave bands are tested. If a subject’s ears are tested, there may be as many as 300 test sites. Such a large amount of testing may take a long time. test time, and even fatigue the subjects leading to threshold errors

In other cases, even the same subject has great differences in their ability to distinguish sounds in different frequency bands. Usually, the human ear is most sensitive to the sound of speech frequency (often referred to as 0.5-4kHz), which can be distinguished in detail. But it is less sensitive to sounds other than speech frequency, and for different subjects, due to individual differences, the ability to distinguish sounds in the same frequency band will also be different
