Audio enhanced hearing protection system
An audio enhanced hearing protection system to be worn by a user includes an ambient noise reduction assembly having a primary noise reduction unit and a secondary noise reduction unit. The audio enhanced hearing protection system also includes an audio input assembly having one or more environmental microphones to receive raw environmental audio signals. The raw audio signals are transformed into processed audio signals via a digital signal processing assembly prior to transmission to a user. The audio enhanced hearing protection system also includes an audio output assembly having at least one speaker to transmit processed audio signals to a user.
1. An audio enhanced hearing protection system to be worn by a user comprising:
an ambient noise reduction assembly,
an audio input assembly comprising a pair of environmental microphones structured to receive environmental audio signals, and wherein each of said pair of environmental microphones is housed in a different corresponding microphone manifold, each microphone manifold mounted to said ambient noise reduction assembly in a binaural configuration,
said audio input assembly is structured and disposed to provide a minimum of 20 degrees of resolution in any direction relative to the user's head,
a digital signal processing assembly comprising a digital processor to transform said environmental audio signals, said digital processor further configured to transform a raw audio signal into processed audio signals, and
an audio output assembly comprising at least one speaker to transmit processed audio signals to the user.
2. The system as recited in claim 1 wherein said ambient noise reduction assembly comprises at least one primary noise reduction unit.
3. The system as recited in claim 2 wherein said ambient noise reduction assembly comprises at least one secondary noise reduction unit.
4. The system as recited in claim 3 wherein said secondary noise reduction unit is interconnected to said primary noise reduction unit.
5. The system as recited in claim 4 wherein said interconnect comprises an adjustable interconnect.
6. The system as recited in claim 1 wherein said audio input assembly further comprises at least one microphone manifold.
7. The system as recited in claim 6 wherein said at least one environmental microphone is housed in said at least one microphone manifold.
8. The system as recited in claim 7 wherein said microphone manifold is configured to at least partially mimic a human ear to mechanically filter said environmental audio signals.
9. The system as recited in claim 1 wherein said raw audio signal comprises said environmental audio signals.
10. The system as recited in claim 1 wherein said audio input assembly comprises a preamplifier.
11. The system as recited in claim 1 wherein said ambient noise reduction assembly is passive.
12. The system as recited in claim 1 wherein said ambient noise reduction assembly is active.
