Interacoustics AC40

The AC40 is a full-featured state of the art audiometer that is a true hybrid combining a stand-alone and PC-based audiometer into one unit. This audiometer features two independent channels that are configurable for either right or left hand operation. The AC40 was developed for the purpose of providing the advanced clinic or training institution with a tool that not only performs all traditional audiometric tests, but also provides a full battery of classic supra threshold tests such as Bekesy, Masking Level Difference (MLD), ABLB, and many more.

The ergonomic design of the AC40 is exceptional with an articulating, high-resolution 8.4" color display that presents crystal clear images for easy to read audiograms, and every test has a dedicated screen to make it easier to monitor results. This feature is particularly useful in training environments. In addition, the AC40 offers features typically found only with PC-based platforms such as Electronic Medical Record (EMR) integration, flexible reporting tools and database storage (NOAH, Diagnostic Suite 2.0), direct print and high frequency options, all in a compact and portable design.
