Interacoustics AT235 Audiometer/Tympanometer
The AT235 is an automatic middle ear analyzer ideal for screening evaluations. The primary design of the AT235 emphasizes ease of use without compromising testing flexibility. Test batteries of the AT235 include standard tympanometry, ispsilateral and contralateral acoustic reflex and reflex decay and air conduction audiometry and ETF testing.
Automated tympanometry may be combined with 2 programmable reflex test batteries. Further manual reflex testing is available for more tests or to confirm/modify automated reflex results. The AT235 allows more than 40 reflex tests per ear to be stored and printed. These capabilities provide the necessary tests for the majority of any clinic’s needs.
Normal Tympanometry:
Interacoustics utilize two beneficial techniques to acquire tympanograms. The first is an ‘endless airflow’ technique which improves the instrument’s ability to obtain a tympanogram on difficult to test patients or when a slight leak is present. This prevents the system from continually resetting to continue the test. The second feature is an intelligently controlled pump system with an adaptive speed control. This feature combines a very fast test speed with high resolution of the tympanogram peak which might otherwise be obtained only with a slower pump speed.
User definable reflex test:
Two user programmable acoustic reflex sequences are available allowing the user to define a simple screening procedure for test A and a more in-depth evaluation as test B. These protocols may be programmed and/or selected by the push of a button. The parameters for test A and B come with a factory default setting but are easily changed to better suit alternative clinical test routines. The protocols allow intensity presentations at fixed levels, in auto threshold mode or a defined sequence to display reflex growth. The AT235 allows mixing of ipsi and contra reflexes in the protocol as well as a variety of stimuli such as pure tones or noise bands. There are few limitations on storing and printing as more than 40 reflexes may be recorded per ear. All reflex testing may be done manually in addition to the automated routines
Decay – Contra and Ipsi:
Acoustic reflex decay testing is available with ispsilateral stimulation as well as with contralateral stimulation. The AT235 comes with a standard single TDH39 transducer for stimulating the contralateral ear.
