1. A system for conveying musical beat information, comprising:
- a sound detector for receiving music and generating a music output signal;
an audio processing unit responsive to the music output signal for providing a beat information output signal, wherein the audio processing unit includes a first amplifier which receives the music output signal and outputs a pre-amplified music signal, and wherein the audio processing unit includes a plurality of channels, wherein a first one of the plurality of channels includes a band pass filter in communication with the first amplifier for passing a predetermined frequency range;
at least one sensory device responsive to the beat information output signal for providing a sensory representation of beat information contained in the beat information output signal; and
a radio transmitter connected to the first amplifier and a radio receiver connected to the band pass filter for radio communication of the pre-amplified music signal to the band pass filter.

Abstract
A beat detection system provides tactile stimulation in response to musical characteristics and in particular to repetitive musical beat information. The device processes multiple acoustic bands and separates out the beat information from each band. Each band provides beat information to respective tactile mechanisms that convey the beat information to the user. The device can be worn by a person with a hearing disability to enable them to appreciate the beat of music.

16. A method for conveying musical beat information, comprising:
-
receiving music;
generating a music output signal corresponding to the music;
processing the music output signal with an audio processing unit to provide a plurality of beat information output signals, wherein the audio processing unit includes a first amplifier for receiving the music output signal to produce a pre-amplified music signal, wherein processing the music output includes filtering the pre-amplified music signal to produce a second signal;
amplifying the second signal with a second amplifier to produce a third signal;
detecting the third signal to produce a fourth signal;
filtering the fourth signal to produce a fifth signal;
filtering the fourth signal to produce a sixth signal; and
relating sixth signal to the second amplifier to control the gain of the second amplifier; and
power amplifying the fifth signal to produce the beat information output signal; and
providing a sensory representation of beat information contained in the plurality of beat information output signals to a user. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
