Claim:
1. A method for providing crosstalk cancelation in a shared acoustic space, the method comprising: receiving, at a first adaptive filter, a first set of sound signals detected by a first microphone in a first zone, the first set of sound signals produced by a first loudspeaker in the first zone; receiving, at the first adaptive filter, a second set of sound signals detected by a second microphone in a second zone, the second set of sound signals including components of the first set of sound signals; determining a first value associated with the first set of sound signals; determining a second value associated with the second set of sound signals; filtering, at the first adaptive filter, the second set of sound signals to cancel the components of the first set of sound signals included in the second set of sound signals, the filtering being based on the first set of sound signals received from the first microphone and based on determining that a ratio of the second value to the first value exceeds a threshold value; and sending, by the first adaptive filter, the filtered second set of sound signals to the first loudspeaker.
