Abstract：
:Temporal modulation transfer functions (TMTF) were obtained from four European starlings (Sturnus vulgaris) using a psychophysical Go/NoGo procedure combined with the method of constant stimuli. The TMTF for a continuous, broad-band noise of 55 dB SPL had a low-pass characteristic with a cut-off frequency of 123 Hz. For an 800 ms gated stimulus of the same sound-pressure level, the TMTF had the shape of a band-pass filter with the most sensitive modulation frequency at around 20 Hz. At 75 dB the band-pass shape of the TMTF was preserved, whereas at 35 dB SPL the TMTF had a low-pass characteristic. The cut-off frequency of the TMTF for continuous noise depends on which part of the spectrum carries the information on the envelope fluctuations. If only sound energy below 1 or 1.5 kHz is modulated, then the cut-off frequencies are 40 and 38 Hz, respectively. If only sound above 3 kHz carries the information on the modulation, then the cut-off frequency is 125 Hz and the shape of the TMTF is similar to that found for broadband noise. The results are discussed with respect to the coding of sinusoidal amplitude modulations by the auditory system and to different measures of time, frequency and intensity resolution in the starling.
