EMAV is a program for measuring and
displaying otoactousic emissions. The distortion-product
otoactousic emission (DPOAE) test features artifact rejection,
measurement-based stopping rules, and noise estimation at the same
frequency as the distortion product. The transient evoked
optoacoustic emission (TEOAE) test features octive-band analysis
and transducer-artifact correction. EMAV requires a high-quality
sound card for stimulus generation and synchronous averaging, such
as CardDeluxe from Digital Audio
Labs.
