Assignee: GMECI, LLC
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A system for dynamic active noise reduction comprising:
at least a physiological sensor configured to:
sense a physiological characteristic of a user; and
transmit a physiological signal correlated to the sensed physiological characteristic;

at least an environmental microphone configured to transduce an environmental noise to an environmental noise signal;
a processor configured to:
receive the environmental noise signal;
correlate at least a component of the environmental noise signal to a physiological parameter of a plurality of physiological parameters of the user, wherein the physiological parameter comprises an arousal response;
generate a noise-reducing sound signal as a function of the environmental noise signal; and
modify the noise-reducing sound signal as a function of the physiological signal and the arousal response, wherein modifying the noise reducing sound signal comprises modifying the noise-reducing sound signal to selectively pass through an impulsive sound of the environmental noise; and

a speaker configured to transduce a noise-reducing sound from the modified noise-reducing sound signal.
