Critical ratios of beluga whales (Delphinapterus leucas) and masked signal duration
This article examines the masking of a complex beluga vocalization by natural and anthropogenic noise. The call consisted of six 150ms pulses exhibiting spectral peaks between 800Hz and 8kHz. Comparing the spectra and spectrograms of the call and noises at detection threshold showed that the animal...
