Abstract
A hearing device, an acoustic apparatus and a sound processing method thereof are provided. The method includes detecting audio signals, determining whether the audio signals include a voice signal of a user, and controlling amplification of the audio signals according to a result of the determination.
Claims20
A method of processing signals in a hearing device comprising a processor, the method comprising:
- detecting audio signals through at least two microphones, wherein the two microphones comprise a first microphone and a second microphone, and wherein the audio signals comprise first audio signals at the first microphone and second audio signals at the second microphone;
- determining, controlled by the processor, whether the audio signals include a voice signal of a user by comparing the first audio signals with the second audio signals based on at least one of time difference information and level difference information of the detected audio signals;
- and
- controlling amplification of the audio signals according to a result of the determination,
- wherein the controlling comprises setting an amplification level of the voice signal of the user such that the voice signal of the user is not amplified.
2 more elements
A hearing device comprising:
- an audio signal detection unit configured to detect audio signals through at least two microphones, wherein the two microphones comprise a first microphone and a second microphone, and wherein the audio signals comprise first audio signals at the first microphone and second audio signals at the second microphone;
- a voice signal determination unit configured to determine whether the audio signals include a voice signal of a user of the hearing device by comparing the first audio signals with the second audio signals based on at least one of time difference information and level difference information of the detected audio signals;
- and
- an amplification control unit configured to control amplification of the audio signals according to a result of the determination,
- wherein the amplification control unit comprises an amplification level setter configured to set an amplification level of the voice signal to be lower than an amplification level of other audio signals.
2 more elements
An apparatus comprising:
- at least two microphones configured to detect sound, wherein the two microphones comprise a first microphone and a second microphone, and wherein the sound comprises first audio signals at the first microphone and second audio signals at the second microphone;
- and
- an amplification control unit, comprising a processor, and configured to control amplification of the sound according to whether the sound includes a voice signal of a user of the apparatus by comparing the first audio signal with the second audio signal based on at least one of time difference information and level difference information of the detected audio signals,
- wherein the amplification control unit comprises an amplification level setter configured to set an amplification level of the voice signal to be lower than an amplification level of other audio signals.
