In addition to playing audio, the AirPods contain a microphone that filters out background noise as well as built-in accelerometers and optical sensors capable of detecting taps and pinches (e.g. double-tap or pinch to pause audio) and placement within the ear, which enables automatic pausing of audio when they are taken out of the ear.
Sorority Noise was an American rock band from Hartford, Connecticut. The band consisted of members from the bands Old Gray (Boucher and Singer, and Ackerman), Prawn (McKenna), Small Circle (Boucher, Singer, and Ackerman), and En Route (Singer).
Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.

Most external microphone designs are of either omnidirectional or noise-canceling type. Noise-canceling microphone headsets use a bi-directional microphone as elements. A bi-directional microphone's receptive field has two angles only. Its receptive field is limited to only the front and the direct opposite back of the microphone.
Two people wearing behind-the-neck earmuffs. Thermal earmuffs are worn for protection from the cold. Because the ears extend from the sides of the head to gather sound waves, they have a high skin surface-area-to-volume ratio, and very little muscle tissue, causing them to be one of the first body parts to become uncomfortably cold as temperatures drop.
Like all echo cancelling processes, these first algorithms were designed to anticipate the signal which would inevitably re-enter the transmission path, and cancel it out. Rapid advances in digital signal processing allowed echo cancellers to be made smaller and more cost-effective.
An effective model for noise control is the source, path, and receiver model by Bolt and Ingard. [8] Hazardous noise can be controlled by reducing the noise output at its source, minimizing the noise as it travels along a path to the listener, and providing equipment to the listener or receiver to attenuate the noise.
