Abstract
Simultaneous tone-tone masking in conjunction with the envelope-follow ing response (EFR) recording was used to obtain tuning curves in dolph ins (Tursiops truncatus). The EFR was evoked by amplitude-modulated pr obes of various frequencies. A modulation rate of 600 Hz was found to fit the requirement to have a narrow spectrum and evoke EFR of large a mplitude. Tuning curves were obtained within the frequency range from 11.2 to 110 kHz. The Q(10) values of the obtained tuning curves varied from 12-14 at the 11.2 kHz center frequency to 17-20 at the 64-90 kHz frequencies.
