Abstract
At least one exemplary embodiment is directed to a communication device that includes a microphone configured to detect an acoustic signal from an acoustic environment, and a processor, configured to detect an acoustical dampening between the acoustic environment and the microphone, based on a change in a characteristic of the acoustic signal and, responsive to the acoustical dampening, apply a compensation filter to the acoustic signal to form a compensated acoustic signal that is reproduced. Other embodiments are disclosed.
Claims3
A headwear comprising:
- a first ambient microphone configured to generate a first ambient signal;
- a second ambient microphone configured to generate a second ambient signal;
- a third ambient microphone configured to generate a third ambient signal;
- a memory that stores instructions;
- a processor configured to execute the instructions to perform operations, the operations comprising:
- receiving the first ambient signal;
- receiving the second ambient signal;
- receiving the third ambient signal;
- applying a filter to the first ambient signal to generate a first modified signal;
- applying a filter to the second ambient signal to generate a second modified signal;
- applying a filter to the third ambient signal to generate a third modified signal;
- determining the approximate location of a vocalization by comparing the first modified signal, the second modified signal and the third modified signal;
- and
- determining that a user of the device has spoken if the approximate location is within a predetermined range of locations.
