1. A method comprising:
- detecting an initial listening zone wherein the initial listening zone represents an initial area monitored for sounds by a microphone array being positioned at a first location;
detecting an initial sound within the initial listening zone; and
adjusting the initial listening zone and forming an adjusted listening zone having an adjusted area monitored for sounds by the microphone array being positioned at the first location, wherein the initial sound emanates from within the adjusted listening zone;
wherein the initial listening zone is adjusted by modifying a set of finite impulse response filter coefficients for the microphone array.

20. A system, comprising:
-
an area detection module configured for detecting an initial listening zone wherein the initial listening zone is to be monitored for sounds by a microphone array being positioned at a first location; a sound detection module configured for detecting a sound emanating from the initial listening zone and for detecting a location of the sound; and an area adjustment module configured for adjusting the initial listening zone based on the location of the sound and forming an adjusted listening zone being monitored for sounds by the microphone array being positioned at the first location, wherein the adjusted listening zone includes the location of the sound; wherein the initial listening zone is adjusted by modifying a set of finite impulse response filter coefficients for the microphone array. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
