14. An audio system comprising:
a microphone;
a loudspeaker; and
processor operable to:
receive, via the microphone, a remote audio signal, wherein the microphone is positioned at least one fourth of a particular wavelength away from a particular location;
identify an unwanted sound in the remote audio signal;
filter the remote audio signal to pass a frequency band of sound to be counteracted, wherein a lower frequency of the frequency band is determined by the particular wavelength;
determine a relationship between a local audio signal, at the particular location, and the filtered remote audio signal; and
generate, according to the local audio signal and the determined relationship, a cancellation signal that, when output by the loudspeaker, will counteract, at least in part, the unwanted sound.
