Abstract:
A numerical sound synthesis method for representing data as audio for use in data sonification employing a Hilbert Space eigenfunction model of human auditory perception is described. The synthesis method comprises approximating an eigenfunction equation representing a model of human hearing, calculating the approximation to each of a plurality of eigenfunctions from at least one aspect of the eigenfunction equation, and storing the approximation to each of a plurality of eigenfunctions. The approximation to each of a plurality of eigenfunctions represents a perception-oriented basis functions for mathematically representing audio information in a Hilbert-space representation of an audio signal space. The model of human hearing can include a bandpass operation with a bandwidth having the frequency range of human hearing and a time-limiting operation approximating the time duration correlation window of human hearing. In an embodiment, the approximated eigenfunctions comprise a convolution of a prolate spheroidal wavefunction with a trigonometric function.

Claim (Index 13):
A method for data sonification optimized for human auditory perception for use in conjunction with human hearing, the method comprising: using a processing device for retrieving a plurality of approximations, each approximation corresponding with one of a plurality of eigenfunctions previously calculated, each approximation having resulted from approximating an eigenfunction equation representing a model of human hearing, wherein the model comprises a bandpass operation with a bandwidth including the frequency range of human hearing and a time-limiting operation approximating the time duration correlation window of human hearing; receiving incoming coefficient information; and using the approximation to each of the plurality of eigenfunctions to produce outgoing audio information by mathematically processing the incoming coefficient information together with each of the retrieved approximations to compute the value of an additive component to an outgoing audio information associated with an interval of time, the result comprising a plurality of coefficient values associated with the calculation time, wherein the plurality of coefficient values is used to produce at least a portion of the outgoing audio information for an interval of time, wherein the modulated signals are summed to produce a composite synthesized signal, and wherein the composite synthesized signal is rendered as at least one audio signal representing audio information to serve represent data with synthesized sound.
