  • Patent number: 4812746
    Abstract: A method of using a waveform to sound pattern converter that produces an audible image of a time dependent signal by digitizing the signal to produce a plurality of discrete level signals, and produces a different audible tone signal for each level of the discrete level signals. A speaker is provided for producing audible sounds and circuitry is provided for driving the speaker to produce an audibly perceptible reference frame indicative of a predetermined time duration and also for driving the speaker with the audible tone signals such that the audible tone signals have the same time orientation with respect to each other as the discrete level signals have in the time dependent signal. The sounds are provided to listener to enable the listener to distinguish the shape of the time dependent signal based on the position and time relation of the tone signals relative to the reference time frame signal.

  • Patent number: 4378569
    Abstract: An apparatus for providing an audible representation of any data which can be represented in a format of M.times.N individual datum. Each datum can have individually specified properties. One application of this technique is to provide an audible representation of a visual scene. Since these data can readily be assimilated by the brain, they can provide either an aid to the visually handicapped or supplementary information to the normally sighted. A matrix of M.times.N pixels is generated in which distance along one spatial axis is represented by discrete sound frequencies and distance along the orthogonal axis is represented by the time lapse following a reference sound pulse. The light intensity of a pixel is represented by the amplitude of the sound at both a particular frequency and a particular time after the reference sound pulse is generated.
