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.
Claims12
A voice pickup system comprising:
- a first earphone configured to fit in an ear of a user, where the first earphone comprises:
- a first Ambient Sound Microphone (ASM), wherein the first ASM generates a first ASM signal;
- a second ASM, wherein the second ASM generates a second ASM signal;
- a first ear canal microphone (ECM), wherein the first ECM generates a first ECM signal;
- a first speaker;
- a second earphone configured to fit in an ear of the user, where the second earphone comprises:
- a third ASM, wherein the third ASM generates a third ASM signal;
- a fourth ASM, wherein the fourth ASM generates a fourth ASM signal;
- a second ear canal microphone, where the second ECM generates a second ECM signal;
- a second speaker;
- a memory that stores instructions;
- and
- a processor that is configured to execute the instructions to perform operations, wherein the processor is coupled to the first ASM, wherein the processor is coupled to the second ASM, wherein the processor is coupled to the first ECM, wherein the processor is coupled to the first speaker, and the operations comprising:
- receiving the first ASM signal;
- receiving the second ASM signal;
- receiving the first ECM signal;
- and
- analyzing the first ASM signal, the second ASM signal, and the first ECM signal to detect if the user is speaking, where the first ASM is configured to have a direction dependent sensitivity to focus on user speech pickup.
