Abstract
A method and system for locating a sound source are provide. The method may include detecting a sound signal of a sound by each of two audio sensors. The method may also include converting the sound signals detected by the two audio sensors from a time domain to a frequency domain. The method may further include determining a high frequency ratio of each of the sound signals in the frequency domain. The method may further include determining a direction of the sound source based on the high frequency ratios.
Claims20
A method for locating a sound source, the method comprising:
- detecting, by each of two audio sensors, a sound signal of a sound source;
- converting the detected sound signals from a time domain to a frequency domain;
- determining a high frequency ratio of each of the sound signals in the frequency domain;
- and
- determining a direction of the sound source based on the high frequency ratios.
A system comprising:
- a sound signal detection module configured to detect, by each of two audio sensors, a sound signal of a sound;
- a sound signal conversion module configured to convert the detected sound signals from a time domain to a frequency domain;
- a sound signal analysis module configured to determine a high frequency ratio of each of the sound signals in the frequency domain;
- and
- a position determination module configured to determine a direction of the sound source based on the high frequency ratios of the sound signals in the frequency domain.
A non-transitory computer readable medium embodying a computer program product, the computer program product comprising instructions configured to cause a computing device to:
- detect, by each of two audio sensors, a sound signal of a sound source;
- convert the detected sound signals from a time domain to a frequency domain;
- determine a high frequency ratio of each of the sound signals in the frequency domain;
- and
- determine a direction of the sound source based on the high frequency ratios of the sound signals in the frequency domain.
