Effect of two levels of masking noise on the hearing threshold of a harbor porpoise (phocoena phocoena) for a 4.0 kHz signal
The 50% detection hearing thresholds of a harbor porpoise for a 4.0 kHz narrow-band FM signal, presented at the background noise level in a pool and with two masking noise levels, were measured using a go/no-go response paradigm and an up-down staircase psychometric method. The masker consisted of a...
