Claim:
1. An automated method for noise cancelation, comprising: receiving first signals from a first plurality of microphones positioned within a microphone array outside a target area; identifying, from the received first signals, a first noise and a first position information for a first source for the first noise external to the target area; determining a cancelation sound for the first noise based on the first noise and the first position information; playing the first cancelation sound as the first noise reaches the target area so as to at least partly cancel the first noise within the target area; receiving second signals from a second plurality of the microphones; identifying, from the received second signals, a second noise and a second position information for a second source for the second noise within the target area; determining a second cancelation sound for the second noise based on the second noise and the second position information; and playing the second cancelation sound to at least partly cancel the second noise.
