Hearing enables sound to be sent to brain auditory center, and feels sound.Hearing aid is generally mechanical, electrical by microphone, amplifier, ear
Source and five part of volume control composition.Hearing aid is divided into air conduction hearing aid and ossiphone by conduction pattern；By usage mode
It is classified as boxlike, spectacle, hairpin-type, behind-the-ear, inner ear type, duct-type, deep duct-type hearing aid.
All the time, dispenser is by the multiple communication with person hard of hearing according to warp when debugging hearing aid
It tests to debug frequency.Thus there is a drawback: dispenser cannot intuitively, accurately experience the variation of specific frequency and listen
Power obstacle person has heard the value of which specific frequency, deploy so later hearing aid person hard of hearing wearing after hear certain
A little frequencies can and actual value deviation it is larger.In consideration of it, how to provide a kind of can allow dispenser to directly detect person hard of hearing band
The threshold value for the specific frequency heard after upper hearing aid is matched more accurate, is made to according to testing result test hearing aid debugging
Being more clear, comfortably of can listening of person hard of hearing wear hearing aid.Hearing aid recruitment evaluation test device is art technology
Personnel need the technical problem solved.
Summary of the invention
It is that specific frequency is empirically debugged by the multiple communication with person hard of hearing for dispenser in the prior art
Rate there is a problem of testing with effect difference；The utility model, which provides, a kind of can allow dispenser directly to detect to obtain person hard of hearing
Take the threshold value after hearing aid to specific frequency, thus hearing aid debugging is tested match it is more accurate so that person hard of hearing is worn
Wear hearing aid listen to be more clear, comfortable hearing aid recruitment evaluation test device.
The utility model using following technical scheme in order to solve the above technical problems, realized:
A kind of hearing aid recruitment evaluation test device, including device noumenon are designed, is equipped with sound in described device ontology
Module and signal input/output module；Operating switch harmony issue device, the operating switch are provided on described device ontology
Module occurs with the sound with the sound issue device to connect；The signal input/output module includes input interface and output
Interface, the input interface are connect with audiometer；The output interface is connect with processing module.
Preferably, the input interface and output interface are arranged on described device ontology.
Preferably, it is additionally provided with power module in described device ontology, module, described occurs for the power module and the sound
Sound issue device and signal input/output module connection.
Preferably, the power module includes battery, the electric energy output end of the battery and the sound occur module,
The sound issue device and signal input/output module connection.
Preferably, described device ontology is equipped with charging interface, and the charging interface and the battery are electrically connected.
Preferably, the sound issue device is loudspeaker.
Preferably, the processing module includes computer.
Preferably, the output interface is USB interface.
The utility model proposes, beneficial effect is:
(1) the utility model can allow dispenser directly to detect and obtain on person hard of hearing band after hearing aid to specific frequency
Threshold value, thus by hearing aid debugging test match it is more accurate so that person hard of hearing wear hearing aid is listened to be more clear, relax
It is suitable.
(2) cooperate debugging hearing aid with utility model device, than the hearing aid that traditional dispenser debugs sounds
It is clear, it is clearly more, accomplish intuitively, quickly, precisely to test the effect with debugging hearing aid, improve the essence of hearing aid fitting
Degree and is tested with quality accuracy.
