SOUND QUALITY BY INTELLIGENTLY SELECTING BETWEEN SIGNALS FROM A PLURALITY OF MICROPHONES
First Claim
1. A method for improving sound reception on a mobile device, comprising:
- obtaining a first sound signal from a first microphone;
obtaining a second sound signal from a second microphone, wherein each of the first and second sound signals includes at least a portion of a first source signal from a first sound source;
obtaining a first signal characteristic for the first sound signal;
obtaining a second signal characteristic for the second sound signal, wherein both the first and second signal characteristics are associated with a same signal characteristic;
weighing the first and second sound signals based on the first and second signal characteristics; and
combining the weighed first and second sound signals to obtain an output sound signal.

Abstract
Sound signal reception is improved by utilizing a plurality of microphones to capture sound signals which are then weighed to dynamically adjust signal quality. A first sound signal and a second sound signal are obtained from first and second microphones, respectively, where the first and second sound signals originate from one or more sound sources. A first signal characteristic (e.g., signal power, signal signal-to-noise ratio, etc.) is obtained for the first sound signal and a second signal characteristic is obtained for the second sound signal. The first and second sound signals are weighed or scaled based on their respective first and second signal characteristics. The weighed first and second sound signals are then combined to obtain an output sound signal.
