Statistical phase analysis of oto-acoustic emissions method, for acoustic screening

摘要

The method detects the presence of oto-acoustic emissions at different, freely selectable frequencies, according to a statistical criterion of the signal and with a definable probability of error. The method can be designed for use with transiently aroused oto-acoustic emissions or with distortion product oto-acoustic emissions. The measurement result can be achieved without a fixed number of measurement cycles, with interim measurements continually calculated to minimise the measurement time, with automatic cessation of measurements when a specific probability of error is achieved.
