The AMBCO OTO-CHEK Audiometer Test Simulator is a ready-to-use Ear Simulator System designed for audiometer calibration checks. The biological simulator replicates a hearing test by a human subject with stable hearing thresholds. A new baseline should be set after every calibration, and the periodic calibration check must be within a range of plus or minus 5 dB of the established baseline (e.g. if baseline at 1000 Hz is 60 dB, any results of 55 - 65 dB are acceptable). The Audiometer Test Simulator will test a frequency range from 125 to 8000 Hz with a continuous or pulsed stimulus format. Lightweight and portable, the OTO-CHEK weighs less than two pounds. OTO-CHEK Calibration Checkers are compatible with any manual audiometer or automatic audiometer with normally open relay contacts. For best results, it is recommended to use the AMBCO OTO-CHEK in a sound booth.

Audiometers are used to evaluate hearing loss and need to be calibrated regularly to ensure accurate and reliable measurements, as mandated by the Occupational Safety and Health Administration (OSHA). The AMBCO OTO-CHEK meets OSHA and other requirements for Biological Audiometer Calibration Checks for Medical Audiometer Products. The Audiometric Calibration Check System includes the OTO-CHEK Test Simulator, headphones, OTO-CHEK cord, AC adapter, and 9V battery. See accessories below for headset accessories, patch cords, patient response hand switch, earphone receiver, autogram pads, and AC adapter. The AMBCO OTO-Chek is proudly made in the USA.
