Claim 10:
11. 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.
