Patent ID: 8787606

Claim:
An apparatus for correcting presbycusis hearing loss comprising: (a) two micro-speakers small enough to fit into the ear canals of a user; (b) connecting the micro-speakers to electronic circuits; (c) tailoring the electronic circuits to compensate for the presbycusis hearing loss; (d) providing microphones capable of receiving sound in the range of 10 Hz to 8000 Hz; (e) providing a power source of sufficient capacity and voltage to enable the device to function for at least 48 hours and to be of sufficiently small size as to fit into a pocket of the user; (f) providing a power source of a rechargeable battery of at least 3 volts; (g) such that the user will be able to hear all frequencies in the range of 10 Hz to 8000 Hz; (h) one of two micro-speakers having a resonant peak region that generally increases in slope (representing an increase in decibels) as the audio frequency increases up to the resonant peak region; (i) the one of two micro-speakers further having a frequency response curve that generally decreases in slope (representing a decrease in decibels) as the audio frequency increases beyond the resonant peak region; (j) a circuit to modify the one of two micro-speakers including a first circuit for modifying the frequency response curve up to the resonant peak region; and (k) a circuit to modify the one of two micro-speakers also including a second circuit for modifying the frequency response curve for audio frequencies higher than the resonant peak region.
