Abstract
The sound suppression apparatus comprises a sound sensing device, configured to sense a sound; and a sound producing device comprising an air-pulse generating device, configured to generate a plurality of air pulses at an ultrasonic pulse rate. The plurality of air pulses at the ultrasonic pulse rate forms an anti-sound. The anti-sound comprises a component which is configured to suppress the sound.
