Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Audition Speech audiometry system provided by the utility model towards test crowd be the child of 3 ~ 6 years old.For the testing feature of child, test macro is divided into two parts by this utility model, is the toy unit mutual with child and the test cell mutual with tester respectively.Wherein, toy unit obtains feedback information for tester according to the interaction scenario of child and toy; Test cell, for playing test word, simultaneously according to the verbal feedback information obtaining child in child and toy unit interaction, thus obtains the audition speech reference value such as speech detection threshold, speech discrimination threshold, Phonetic balanced maximum of child further.
In test process, play children's vocabulary adjacency test macro by test cell and play test word, tester by coordinating game between toy unit with child, thus obtains the audition Speech audiometry result of child.Respectively toy unit and test cell are described in detail below.
First introduce the toy unit mutual with child, this toy unit is used for tester and sets up a conditioning reflection to child.Tester sets up game rule according to toy unit, in the process that child plays games, indirectly obtains required test result.
See Fig. 1, toy 1 belongs to Quoits toy, comprises base and some motley lassos, wherein base is provided with conical or columniform lasso bar.This toy volume is more greatly and relatively simple, lower to the fine movement Capability Requirement of child, can be used to test young child, as about 3 years old.Post holes toys photo in Fig. 2 is comparatively more difficult with lasso, comprises a base, base is provided with some apertures in a row in column.Aperture can hold small cylinder just.The hole of small cylinder is less, improves the fine movement Capability Requirement of child.And small cylinder is except varying in color, simultaneously different in size, specific moulding can be put.This just needs the creativity of child and imaginative power to participate in, and also increases to the requirement of its cognitive competence, is applicable to age slightly large child.Test toy can certainly be selected, such as little inserted sheet, ball etc.
This toy unit needs to possess following characteristics: stabilized structure, occurs that toy caves in when avoiding child to play games; Color and luster enriches, and chromatic colour more can attract the attention of child; Intention nicknack, needs child to have cooperated with game on one's own initiative; Can not choose acoustic toy, collide outside sent sound namely between toy, toy self can not be sounded.In test process, the toy that child selects not is unalterable.When child loses interest to some toys, need to change toy immediately, ensure that child can complete test accurately and effectively.
Then test cell is introduced.After tester determines that child has been familiar with the game rule of toy unit, then can carry out audition Speech audiometry by test cell to it.See Fig. 3, test cell provided by the utility model comprises computer 1 and is placed in the audio frequency adapter 2 of computer outside.Computer 1 is connected by USB interface 50 with audio frequency adapter 2.Wherein, audio frequency adapter is used for receiving and sending audio-frequency information, comprises Audio Input Modules 3, control treatment module 4 and dio Output Modules 5.Audio Input Modules 3 receives the simulated audio signal from the input of external audio source 6, inquiry mike 7 and feedback microphones 8, and is translated into digital audio and video signals.Wherein inquiry mike 7 and feedback microphones 8 are for AC regeneration test result between tester and tested personnel.Digital video signal is transferred to computer 1 through USB interface 50 by control treatment module 4, and machine 1 to be calculated processes rear output feedack audio file, then is transferred to control treatment module 4 through USB interface 50.After control treatment module 4 obtains audio file, and transfer digital audio and video signals to simulated audio signal by dio Output Modules 5, output to audiometric earphone 12, monitoring headpone 11, external loudspeaker 10 and external audio receptor 9.Wherein, audiometric earphone 12, monitoring headpone 11 are respectively used to tested personnel and listen to content measurement and tester's snoopy test result.
Fig. 4 is the structural representation of audio frequency establishing device inside.Wherein control treatment module 4 comprises digital signal processor 20 and USB controller 21.Wherein digital signal processor be used for converting digital signal, the process such as filtering, its inside also comprises flash memorizer.USB controller 21 is communicated by USB interface 50 between audio frequency adapter 2 with computer 1 for controlling.Audio Input Modules 3 comprises analog-digital converter 22, filter amplifier 23,25,27 and feedback microphones interface 26, inquiry microphone interface 24, outside input audio interface 28; The signal that wherein each interface imports into is sent to digital signal processor 20 after filter and amplification, analog digital conversion.Dio Output Modules 5 comprises digital to analog converter 29, audio frequency amplifier 30,32,34,36 and monitoring headpone interface 31, audiometric earphone interface 33, external loudspeaker interface 35, outside output audio interface 37; Wherein the audio signal of digital signal processor 20 transfers to each interface to export after digital-to-analogue conversion is amplified.Wherein, based on the hyperactivity of child, each audio frequency input and output interface of this utility model preferably adopts wave point, is convenient to the safety, the reliability that add test cell while child wears.
When the audition Speech audiometry system provided utilizing this utility model is tested, tester is first needed to be that child selects suitable toy.When child can skillfully participate in tester for its game selected after, tester just accurately can obtain the audition speech result of child by test cell.In test process, play test word by test cell, simultaneously the audition Speech audiometry result of tester by coordinating the mode of game to obtain child with child.By the audition Speech audiometry result of child, can know child in its growth promoter some stages to the perceiveing of speech, identification ability, after can using auditory prosthesis to listening barrier child, the assessment of effect provides foundation simultaneously.
Above the audition Speech audiometry system of children-oriented provided by the utility model is described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from this utility model connotation, all by formation to this utility model infringement of patent right, corresponding legal responsibility will be born.
