<p>The invention proposes a method for estimating the distance from a sound source to one or two sound sensors, the method comprising the following steps:
- using the sound sensor(s), recording a sound signal from a sound source,
- computing audio features of the recorded sound signal, the audio features including at least the mean signal energy,
- estimating the signal energy produced by the sound source based on signal characteristics other than the means signal energy,
- correcting the computed signal energy using the estimated signal energy, and
- mapping the corrected signal energy to an estimated distance of the sound source to the sound sensor.</p> |
