Description
Technical field
The present invention relates to a kind of test equipment, particularly relate to a kind of audiometry measuring sound localization ability
System.
Background technology
Hearing test or to claim audiometry be by observing experimenter to the reaction caused by sonic stimulation, with
Solve auditory function state and the inspection of diagnostic hearing system disease.The purpose of hearing test is clearly with or without listening
Power obstacle, the degree of hearing loss and the character of hearing loss and position.The mesh that sound localization checks
Mainly detection experimenter's angle perception to sound source position.Can be used for different age group or difference is listened
Power impaired sound localization capability study, and to the hearing assistance devices such as sonifer, artificial cochlea
Use after rehabilitation efficacy research.
In existing sound localization technology, audiometry storehouse is usually a cube structure, installs in measuring storehouse
There is multiple audio amplifier.Experimenter is sitting in audiometry storehouse, and tester controls one of them audio amplifier and sends sound,
Experimenter points out audio amplifier or the left and right directions of sound source；Tester records the result root repeatedly tested
The audiometry results of experimenter is calculated according to corresponding algorithm.
By foregoing it can be seen that prior art needs tester's artificial sample and calculates audiometry
As a result, inside existing audiometry storehouse, it mostly is rectangular structure, is positioned at the internal near wall audio amplifier of audiometric room
Sent sound is different due to opposing sides position, and wall has different anti-for different frequency sound
Penetrate rate so that the identical sound source of diverse location sends sound to be had the most very much not at test position gained spectrum signature
With, and make experimenter remember difference possibly through the spectrum distribution feature of diverse location audio amplifier sounding
Audio amplifier, this can affect the sampling accuracy of test data, influence whether the accuracy of test result equally.
Experimenter is it can be seen that audio amplifier position, and test result is to point out the audio amplifier position of thought sounding, and not
It is the sound position directly pointing out to experience, there is certain error；And in test process, tested
The position of person's head, posture can not be effectively ensured when each test tone sends and all remain concordance, i.e. sees
To the center origin direction of test requirements document.And can not effectively record in test process experimenter's head,
The reactions change that sound position is made by hordeolum.
