Model:

BA-202 Bio Acoustic Simulator

Key Features:

  • Bio-Acoustic Simulator

Description:

The Quest BA-202 series of Bio-Acoustic Simulators are used to perform the daily biological check for manual, automatic and microprocessor based audiometers.

These simulators eliminate the subjective results, costs, problems, and errors associated with using human subjects for the daily check.

As an added benefit, the BA-202-25 and BA-202-27 can also be used to continuously monitor room background noise in octaves
