Convention Paper

A Perceptual Gain-Control Technique for Bioacoustic Transient Detection

Authors: Melinger, David K.; Clark, Christopher W.

AES Convention 95 · Paper 3709 · October 1993

Abstract

This paper addresses the problem of detecting finback whale (Balaenoptera physalus) calls-20-30-Hz one-second noise bursts-in a high-noise (0-15-dB SNR) environment. The solution is to compute a spectrogram, apply faster narrow-band loudness masking with loudness normalization, and threshold the output. Test results for several recordings, a comparison with other methods, and limitations of the technique are covered.
