Abstract
Systems and methods for removing noise from an audible signal are provided. More particularly, a vibration sensor is used to obtain a vibration signal from an environment including a communication device. The signal from the vibration sensor is combined with a signal from a microphone associated with the communication device, to create a modified audible signal. More particularly, a filtering or subtraction process can be performed with respect to the audible signal, at a time corresponding to an event detected as part of the vibration signal. The resulting modified audible signal can have reduced noise as compared to the original audible signal.
Claims20
A communication system, comprising:
- a first microphone in a first communication device;
- a second microphone in a second communication device;
- a plurality of vibration sensors comprising at least a first vibration sensor in the first communication device and at least a second vibration sensor in the second communication device;
- and
- a filter, wherein a plurality of vibration signals from the plurality of vibration sensors are received at the filter, wherein a first audible signal from the first microphone and a second audible signal from the second microphone are received at the filter, wherein the filter applies the plurality of vibration signals from the plurality of vibration sensors to modify the audible signals from the first microphone and the second microphone, and wherein the filter outputs a modified audible signal.
A method of removing non-speech noise from a plurality of audible signals, comprising:
- receiving a first audible signal at a first microphone in a first communication device;
- receiving a second audible signal at a second microphone in a second communication device;
- receiving a plurality of vibration signals at a plurality of vibration sensors comprising at least a first vibration sensor in the first communication device and at least a second vibration sensor in the second communication device;
- providing the first and second audible signals and the plurality of vibration signals to a filter;
- modifying, in the filter, the first and second audible signals by applying the plurality of vibration signals to create a modified audible signal;
- and
- outputting from the filter the modified audible signal.
A non-transitory computer readable medium having stored thereon computer executable instructions, the computer executable instructions causing a processor to execute a method for removing non-speech noise from a plurality of audible signals, the computer executable instructions comprising:
- instructions to receive a first audible signal from a first microphone in a first communication device;
- instructions to receive a second audible signal from a second microphone in a second communication device;
- instructions to identify a plurality of non-speech signals received from a plurality of vibration sensors comprising at least a first vibration sensor in the first communication device and at least a second vibration sensor in the second communication device;
- and
- instructions to modify the first and second audible signals to remove at least a first portion of the first and second audible signals corresponding to the identified plurality of non-speech signals received from the plurality of vibration sensors.
