Auditory paradox based on fractal waveform.

M R Schroeder

    The Journal of the Acoustical Society of America
    |January 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    Researchers synthesized paradoxical acoustic waveforms that sound lower at higher playback speeds. One waveform played at double speed sounds a semitone lower, defying typical pitch expectations.

    Area of Science:

    • Acoustics
    • Signal Processing
    • Psychoacoustics

    Background:

    • Standard acoustic principles dictate that increasing playback speed raises pitch.
    • Paradoxical auditory phenomena challenge conventional understanding of sound perception and reproduction.

    Purpose of the Study:

    • To describe the synthesis of novel acoustic waveforms with counterintuitive speed-pitch relationships.
    • To investigate the physical and perceptual characteristics of these paradoxical waveforms.

    Main Methods:

    • Synthesis of specific paradoxical acoustic waveforms.
    • Magnetic tape recording and playback at varied speeds.
    • Acoustic analysis and psychoacoustic evaluation.

    Main Results:

    Related Experiment Videos

    • Demonstration of waveforms sounding lower at higher playback speeds.
    • Specific example: a waveform sounding a semitone lower at double speed, contrary to an expected octave increase.
    • Illustration of connections between these waveforms and fractal geometry.

    Conclusions:

    • Successful synthesis of paradoxical acoustic waveforms exhibiting inverse speed-pitch relationships.
    • These findings offer new insights into acoustic physics and signal processing.
    • The study highlights potential links between acoustics and fractal geometry.
