Abstract
Aspects relate to systems and methods for dynamic active noise reduction including at least a 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, 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 a speaker configured to transduce a noise-reducing sound from the modified noise-reducing sound signal.

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.
A method of dynamic active noise reduction comprising:
- sensing, using at least a physiological sensor, a physiological characteristic of a user;
- transmitting, using the at least a physiological sensor, a physiological signal correlated to the sensed physiological characteristic;
- transducing, using at least an environmental microphone, an environmental noise to an environmental noise signal;
- receiving, using a processor, the environmental noise signal;
- correlating, using the processor, 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;
- generating, using the processor, a noise-reducing sound signal as a function of the environmental noise signal;
- modifying, using the processor, 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
- transducing, using a speaker, a noise-reducing sound from the modified noise-reducing sound signal.
