Detailed description of the invention
This utility model provides a kind of multi-functional sonometer, can realize for the hearing test demand under different situation; Meanwhile, good testing precision is realized.
In order to make those skilled in the art person understand technical solutions of the utility model better, below in conjunction with the drawings and specific embodiments, the multi-functional sonometer of one that this utility model provides is further described.
Embodiment 1, refers to Fig. 1, is an example structure schematic diagram of a kind of multi-functional sonometer that this utility model embodiment provides, and wherein, sonometer comprises controller 1, starts module 2, enquiry module 3 and drive circuit 4; In the present embodiment, controller 1 has the function of the operation controlling sonometer, starts module 2 and has according to default rule, start the function of corresponding enquiry module 3; Enquiry module 3 has measuring ability; And drive circuit 4 is mainly used in driving the circuit of sonometer to run, wherein, controller 1 is connected with startup module 2, enquiry module 3 respectively by drive circuit 4, arranged by the connection of modules, this sonometer is made to possess inquiry measuring ability, meanwhile, realize the function detected, play audiometric effect.
Consult Fig. 2, enquiry module 3 comprises audio detection unit 31, language Hearing esamination unit 32, special detection unit 33, wherein, audio detection unit 31 is for conductance earphone and osophone, and provide and comprise left ear stimulation sound and auris dextra masking noise or left ear masking noise and auris dextra stimulation sound, its moderate stimulation sound comprises pure tone, sound of twitering, and noise comprises narrow-band noise, white noise, language Hearing esamination unit 32 provide comprise monaural voice signal, monaural voice signal and contralateral masking noise, monaural Mixed design signal, ears input different phonetic signal, ears masking noise, wherein voice signal can be mike (MIC), magnetic tape controller (CD), and noise comprises narrow-band noise, white noise, special detection unit 33 possesses SISI and detects, ABLE detects, STENGER detects, HIS measuring ability, SISI wherein detects and is called short increment sensitivity index test, for checking the diagnostic ability that audition changes intensity of sound trace, with the pure tone of 1000Hz, intensity is above threshold 20dB, application amplitude modulation apparatus makes every 5 seconds of the sound intensity occur once, and the 1dB increment of journey in short-term (to rise and fall time is respectively 50ms, continue 200ms), person under inspection listens 20 amplification sounds altogether, often hear 1 time, score 5%, total score is normal below 30%, 35 ~ 65% is suspicious, more than 70% person is the recruitment test positive, the existence of prompting cochlear lesions.
ABLE detects and is called alternate binaural loudness balance test, is check the common method with or without loudness recruitment, is suitable for the patient of binaural listening difference 20 ~ 50dB (HL).When stimulating with low-intensity sound, comparatively another ear audition is poor for one ear, but when high strength sound stimulates, the loudness that the tone of two ears to same frequency is experienced may be equal, even poor ear is responsive on the contrary, the comparatively strong side of this Ipsilateral intensity increase is fast phenomenon, claims recruitment phenomenon (recruitmentphenomenon).The perceptive deafness that cochlear lesions causes often has loudness recruitment.The auris dextra threshold of audibility of such as patient is 0dB, and the left ear threshold of audibility is 40dB.When auris dextra sound intensity level increase 20dB time, left ear need only from its threshold of audibility (40dB) increase 10dB just feel diotic hearing to loudness equal, namely this indicate loudness recruitment, prompting there is cochlear lesions.Inspection method is first measure patient two ear pure tone audiometry, selects diotic hearing power to differ the frequency of more than 20dB, and every 10 ~ 20dB mono-grade ground increases the sound intensity of an ear, and when the loudness regulating sound intensity to two ear of another ear to feel by shelves is identical till.
STENGER detects and is called that malingering deafness immediate shipment is deaf, refers to that auditory system is without significant organic pathological changes, and audition is normal, and ear calls oneself deafness.Malingering deafness person there is no neuropsychological wound, often pretends with object or attempt, and subjective expression is very serious, contributes to differentiating by Audiometry repeatedly and objective audiometric inspection.Simultaneously inspection method thinks that two ears send same frequency tonal signal, and for the good ear of audition, sound intensity can arrange threshold values higher than 10dB, can arrange threshold values lower than 10dB for poor ear.
HIS detects and refers to and carry out sonifer simulation process according to audiogram.
The sonometer that this utility model embodiment provides also is provided with audio-frequency generator, audio drive circuitry and earphone drive circuit; This audio-frequency generator is connected with controller 1 by audio drive circuitry, and audio-frequency generator is used for energized gas guide lug machine and osophone; The Signal transmissions that earphone drive circuit is used for audio-frequency generator to produce is to earphone.
