Abstract
Sound capture and reproduction devices that can be mounted on hearing protective headsets, and are capable of using multiple microphones to determine the origins of one or more acoustic signals relative to the devices orientation, as well as methods of acquiring the origins of a combination of one or more acoustic signals from at least two microphones are described.
Claims22
A sound capture and reproduction device, comprising:
- two microphones localized at two regions;
- and
- a processor, wherein the processor is configured to:
- receive one or more acoustic signals from the two microphones localized at two regions,
- compare the one or more acoustics signals between the two microphones, and
- quantitatively determine the origin of the one or more acoustic signals relative to the device orientation.
16-23. (canceled)
A method of acquiring the origins of a combination of one or more acoustic signals from two microphones, comprising the steps of capturing the one or more acoustic signals, comparing the one or more acoustic signals from two microphones, and quantitatively determining the origin of the one or more acoustic signals relative to the device orientation.
