ACAMŽ is an audiometer with optional components for performing Real Ear Measurements (REM) Hearing Instrument Testing (HIT) and loudness scaling. It is intended to aid trained audiologists and hearing aid professionals in the diagnosis of hearing loss and the fitting of hearing aids. As a

part of the REM and HIT modules ACAM performs several kinds of signal analysis including root mean squared (RMS), fast Fourier transformation (FFT) and percentile analysis (PA). ACAMŽ gives an audiologist the ability to use one or any combination of the diagnostic tools recommended

by the National Acoustics Laboratory (NAL) and Dr. Richard Seewald (DSL-IO). Available ACAMŽ 5 hardware consists of an audiometer with a modular control unit for peripheral

components, which include a large or small hearing instrument test box and an in situ ear probe for real ear measurement. Headphones for audiometry, bone conduction and loudness scaling, loudspeakers, a microphone and an interrupter switch are available for use with the audiometer.

ACAMŽ's operational software meets the international software standards established by the Hearing Instruments Software Manufacturers Association (HIMSA) and the speech recognition standards (ISTS, International Speech Test Signals) established by the European Hearing

Instrument Manufacturers Association (EHIMA).

The ACAMŽ system meets or exceeds the following international standards; IEC 60645, ISO 8253, ISO 16832, ANSI S3.6, ANSI S3.22, EN 60118-0, EN 60118-7, DIN IEC 60118-15, ISO 12124, ANSI S3.43

ACAMŽ should be operated by individuals with education and training in the field of audiology such as audiologists, hearing aid dispensers, health care and school nurses and ear nose and throat specialists.
