Untitled (Subject: Reverberation), Richard C. Heyser
Unpublished Writings
In this paper, Richard C. Heyser explains how sound reverberates and why he developed a time delay spectrometer (TDS) to measure sound.
The Two Parts Of Energy, Richard C. Heyser
The Two Parts Of Energy, Richard C. Heyser
Unpublished Writings
In this paper, Richard C. Heyser explains the theories behind measuring sound by discussing its energy. Using what he calls abstract geometry, Heyser argues that measuring the transfer properties (that is, pressure and velocity) of sound's energy aids in the discovery of its amplitude and phase (or in-phase and quadrature).
The Impulse And Doublet, Richard C. Heyser
The Impulse And Doublet, Richard C. Heyser
Unpublished Writings
The basic problem to which this paper is directed is that of characterization of the acoustic field perceived by an observer and due to a loudspeaker situation in a room. Before immediately jumping into an apparent solution and presenting the results of a set of measurements it is essential to present the considerations leading to that measurment...First, there are at least two ways of characterizing the same acoustic signal if we restrict our attention to a well defined set of parameters...Secondly, since both characterizations define the same thing it must be possible to translate information without loss from one domain …
