Abstract

Sine sweeps used as excitation signals provide a way to measure linear impulse response and harmonic distortion simultaneously. This technique is applicable to measurements of room acoustics as well as audio equipment. In this paper, both linear sweep and exponential sweep measurement procedures and results are presented. A novel amplitude modulation scheme for exponential sweep measurement is also described.
