Alternatively, antinoise waves can be created digitally, using a signal processor to convert incoming sound waves into a stream of numbers. Given those numbers, computers can quickly calculate the frequency and amplitude of the mirror-image waves. Those specifications are then fed to a conventional speaker and broadcast into...
