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.
