GZ-0702 audiometer is a computer control hearing test equipment that combine by several functional modules. It¡¡¥s a Microcomputer hearing evaluation tool which develop base on hearing test and the Acoustic requirements of hearing-aid fitting. GZ-0702 audiometer use for pure tone test,be suitable for hospital ENT diagnose and hearing-aid fitting,or clinical/family and outer ambulant hearing test. Test could proceed by TDH39 air conduction.test signal including pure tone,pluse voice and warble tone. GZ-0702 audiometer provide 11 air conduction test frequency point, frequency range from 125Hz to 8KHz,dB HL from 0 to 110. GZ-0702 audiometer also provide 11 bone conduction test frequency point, frequency range from 125Hz to 8KHz,dB HL from 0 to 70(the standard is from 250Hz to 6000Hz). All of the test data result could be automatic switch to pure tone audiogram and calculate patient¡¡¥s PTA value automatically. All of the test data result could be automatic switch to pure tone audiogram and calculate patient¡¡¥s PTA value automatically. The structure of audiometer make it convenient for service,and autotest make it easy to debugging and annual calibration.
