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.
