Untitled (Subject: Reverberation), Richard C. Heyser
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Unpublished Writings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.
Alternatives In Quantum Theory, Richard C. Heyser
Alternatives In Quantum Theory, Richard C. Heyser
Unpublished Writings
Quantum mechanical descriptions in terms of momentum and position are identified as alternatives under the condition of equal complex-vaulted Lebesgue square integrability. While this does not change any of the formal results obtained in quantum mechanics, it does shed a different interpretive light on the steps that lead up to these results. Instead of being independent, even in concept, momentum and position are identified as being the same thing, merely seen from different views. Neither is required to complement the descriptive capability of the other, since each forms a complete alternative in its own right. Apparent complementarity, as well as …
The Etc And Instantaneous Intensity, Richard C. Heyser
The Etc And Instantaneous Intensity, Richard C. Heyser
Unpublished Writings
Richard C. Heyser explains how to measure the energy-time response of an acoustic signal by expressing the energy density in a logarithmic form, which he cales the Energy-Time Curve (ETC).
Untitled (Subject: Energy), Richard C. Heyser
Untitled (Subject: Energy), Richard C. Heyser
Unpublished Writings
Fundamental energy relations are explored as a basis for the measurement of physical systems. By considering finite dimensional observations in linear Hilbert space it is shown that a necessary and sufficient condition for the conservation of energy is the partitioning of any observation of that energy into two components which will be related through the Hilbert transform. The consequence of this relationship is demonstrated for the equilibrium storage of energy, point-wave duality in measurements, significance of complex representations involving circular form, the meaning of minimum phase and all-pass properties, and the introduction of new measurement characterizations such as the energy-time …
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Unpublished Writings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).
Brief Theory Of Coherent Processor, Richard C. Heyser
Brief Theory Of Coherent Processor, Richard C. Heyser
Unpublished Writings
The particular coherent data processor which is to be discussed relies heavily upon several basic concepts. These concepts represent a departure from conventional practice and hence the theoretical description must await their presentation in order to gain some continuity. We will accordingly present the underlying assumptions and signal physics prior to description of the processor itself.
Reducing Uncertainty, Richard C. Heyser
Reducing Uncertainty, Richard C. Heyser
Unpublished Writings
Intended for audio engineers, Richard C. Heyser meant for this paper to bring attention to the misapplication of the theoretical concept, the Uncertainty Principle. Heyser argues that this concept has been "freely applied without regard to the errors which may result due to lack of understanding of its derivation."
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 …
