Abstract
A system for masking a perceived sound includes a wearable device disposed on a person, the wearable device including in a plurality of sensors, each of which is configured to output a sound waveform in response to sounds generated by physiological activity of the person. The system also includes a processing device coupled to the plurality of sensors and configured to process the sound waveforms. The system further includes a sound output device coupled to the processing device, the sound output device is configured to output the sound waveforms to mask a perceived sound.
Claims20
A system for masking a perceived sound, the system comprising:
- a wearable device disposed on a person, the wearable device including a plurality of sensors, each of which is configured to output a sound waveform in response to sounds generated by a physiological activity of the person;
- a processing device coupled to the plurality of sensors and configured to process the sound waveforms, wherein the sound waveforms are categorized based on at least one of an amplitude or a resolution thereof to enhance playback clarity and stored as sound files;
- and
- a sound output device coupled to the processing device, the sound output device is configured to output the sound waveforms to mask a perceived sound.
A method for masking a perceived sound, the method comprising:
- placing a wearable device on a person, the wearable device including a plurality of sensors;
- generating a sound waveform at each sensor of the plurality of sensors in response to sounds generated by a physiological activity of the person;
- processing at a processing device the sound waveforms, including:
- categorizing the sounds based on at least one of an amplitude or a resolution thereof to enhance playback clarity;
- and
- storing the categorized sounds as sound files;
- and
- outputting the sound waveforms through a sound output device coupled to the processing device to mask a perceived sound.
A system for masking a perceived sound, the system comprising:
- a wearable device disposed on a person, the wearable device including:
- a band formed from an elastic material configured to induce arterial stenosis thereby increasing blood flow turbulence;
- and
- a plurality of sensors, each of which is configured to output a sound waveform in response to sounds generated by a physiological activity of the person, wherein the plurality of sensors includes:
- at least one ultrasound sensor disposed on an inner surface of the band and configured to measure sound generated by blood flow, wherein, for nonturbulent blood flow, the measured sound is presented as sound waveforms using the Doppler effect;
- and
- at least one acoustic sensor disposed on an outer surface of the band and configured to measure external sounds;
- a processing device coupled to the plurality of sensors and configured to process the sound waveforms, wherein the sound waveforms are categorized using machine learning based on at least one of an amplitude or a resolution thereof to enhance playback clarity and stored as sound files, wherein the categorization further includes ongoing training to automatically identify the sound waveforms using machine learning;
- and
- a sound output device coupled to the processing device, the sound output device is configured to output the sound waveforms to mask a perceived sound.
