DESCRIPTION
The GSI 38 is an automatic acoustic admittance and reflex measurement system with
a screening audiometer. The instrument consists of a probe and a desk-to-base
interconnected via a cable. It is a combination of GSI 17 and GSI 37 plus acoustic
reflex testing capabilities, both ipsilateral and contralateral. The audiometric portion is
a single channel pure tone audiometer, with a pair of air-conduction earphones. Int he
tympanometric mode, the measurement of acoustic admittance is corrected for the
acoustic admittance of the external auditory meatius, and the ear canal volume is
displayed. Also a test cavity assembly is provided.
INSTRUCTION MANUAL
The GSI 38 is supplied with an instruction manual which meets the requirements of the
applicable standards.
