Abstract

The effect of varying the signal level on the magnitude response of a head-related transfer function measurement was investigated. Measurement signals with levels ranging between 56 and 86dB SPL were presented over a loudspeaker and recorded using blocked meatus microphones placed in a dummy head. Results indicate that, relative to a 74 dB reference level, for measurement signals below 62dB and above 80dB SPL (1) interaural level differences increase as a function of decreased signal level, and (2) the ipsilateral ear shows a variance in spectral notch depth and center frequency location.
