Description:

The AM-232 is a single-channel, air-conduction audiometer engineered for occupational screening and family practice. Twelve discrete frequencies from 125 Hz to 8 kHz are delivered through TDH-39 headphones at intensities from –10 dB HL to 90 dB HL in 5 dB steps; a +10 dB push button extends output to 100 dB. Mode keys present steady, pulsed or FM-warble tones, improving threshold detection in children and adults with tinnitus. A rotary attenuator and frequency dial give tactile confirmation even with gloves, and the hinged lid conceals headset and patient-response switch for transport. The molded ABS enclosure weighs just 6.5 lb and contains a battery compartment for field calibration checks.

Economic Advantage:

Because it draws power only for its LED indicators, the AM-232 operates indefinitely from mains or optional battery eliminator, cutting long-term costs versus PC-based audiometers that require computers and sound-treated rooms. Its integrated warble stimulus exempts many workplaces from buying separate Type B sound booths for basic OSHA compliance, saving thousands in setup fees.
