The AC40 is an advanced clinical audiometer with high frequency capability. It features preprogrammedand automated testing with a large LCD screen to make testing easier. The AC40 comes standard with high frequency audiometry, multi-frequency, MLD, built-in free field amplifiers and more.
The true independent channels of the AC40 make it stand above other audiometers. The AC40 lets you simultaneously present different frequencies to opposite ears. This flexibility allows for tests like the MLB but more importantly for complex signal mixing situations like speech in noise simulations.
Test frequencies can be set in 1/24 octave increments up to 20 kHz. This makes the AC40 ideal for tinnitus measurements and ototoxicity monitoring.
Speech Display
A tabular display for speech testing allows for quick data entry of SRT, multiple word recognition test scores with a variety of transducer selections. Two buttons on the front panel enable you to quickly score the tests and enter them into the display. All masking information is provided automatically. An alternate speech audiogram display is available for calculation of the PBI.
