The Invention*

high frequency hearing device

to supplement an existing acoustic hearing instrument by

providing a treble boost and extension

which is missing from all existing products

* Patent Pending

UltraPitch™ hearing device

	High frequency speech information can be sent to the brain by using our patented bone conduction technology that by-passes the low frequency filter of the outer and middle ears. High frequency speech sounds can be emphasized, thus improving intelligibility even in high noise. Those individuals with hearing loss can re-experience high fidelity, high pitched music as well as speech.


Upper Trace: Natural speech waveform Lower Trace: STS modulated waveform	High frequency enhancement Rapid filtering and modulating algorithms consonant gain boost ~8dB power ~110 dB re: 1 µN

Problems and Solutions

High audio (< 20 kHz) distortion of high frequency consonants modulation on brain resonances via bone conduction acoustic feedback separation between modulating and carrier frequencies occlusion of ear canal bone conduction functional gain more with high audio~
