The AC33 is a two channel clinical audiometer designed for use in clinics, hospitals and by hearing aid fitters who require two channel testing capability. Carefully designed operation procedures ensure fast and reliable performance of all standard clinical audiometric tests. The easy to read display, together with the functional layout of the front panel, makes normal manual testing easy and comfortable. In addition pre-programmed tests, some with automatic scoring, are incorporated for threshold testing, speech testing and SISI tests.
In a modern clinical environment it is important to provide interconnection with computers. The AC33 is therefore equipped with computer interface to accommodate this and a range of support software is available. The AC33 is also fully compatible with NOAH.
