It is intended for diagnostics of a condition of acoustical function of the patient by method of a tone threshold and superthreshold audiometriya on air and bone conductivity, a speech audiometriya.
It is applied in department of otorhinolaryngology, surdology and audiology of medical institutions.
Technical characteristics: Number of channels: two certain identical canals.
Intensity of a sound signal:
By air: from - 10 to 120 dB of HL, steps 5 dB;
Up to a bone: from - 10 to 80 dB of HL, steps 5 dB.
Parameters of the tone test:
Range chastot: dlya measurements by air - from 125 to 20000 Hz;
For measurements up to a bone - from 250 to 8000 Hz.
Types of signals: true tone, a trill, an impulse, the pulsing tone, an ulsiruyushchy trill, chastotnospetsifichesky noise of FRESH, the pulsing chastotnospetsifichesky noise of FRESH. Masking: ipsilateralny (the tested ear) and contralateral (an opposite ear) narrow - band, white and speech noise. 2 microphones for reproduction of "the live speech" on the flexible holder allow to carry out binaural speech testing.
