Abstract

The need for data on the perception of sounds produced by the excitation of resonance systems is discussed in relation to speech and psycho-acoustics. The voltage response of a series of N decoupled low-pass resonator sections to the sudden application of various types of input pulse trains is reviewed.

The output of such a series of resonators to a recurrent impulse which is suddenly applied contains a d.c. term, a series of transient terms at the uncoupled resonator frequencies, and a steady-state term involving the harmonics of the input pulse train. A circuit for psychophysical tests is described which provides a number of discrete positions of resonator frequency and damping. Sound spectrographic analyses demonstrating the transient and steady-state terms for a single resonator are presented.
