Learn how noise-cancelling headphones use active noise control (ANC) to suppress unwanted ambient sounds and improve audio quality. Find out the theory, applications, benefits, drawbacks and history of ANC technology.
A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.
Learn about audio headsets, a combination of headphone and microphone that connect to telephones, computers or mobile phones. Find out the different styles, designs, compatibility and functions of audio headsets for various applications.
A boundary microphone is a condenser mic with a capsule near or flush with a surface, such as a floor, table, or wall. It provides a directional pickup pattern and a phase-coherent output signal, and is used for piano, hockey, conference, and musical applications.
Learn about the origin and evolution of headphones, from the first telephone receivers to the modern wireless earbuds. Discover the different types of headphones, such as circumaural, supra-aural, earbuds, and bone conduction, and how they connect to various audio sources.
Learn about the history, types, and applications of wireless microphones, also known as radio microphones. Wireless microphones transmit audio signals by radio waves to a receiver unit, allowing free movement and flexibility for performers and speakers.
Bone conduction is the transmission of sound to the inner ear through the skull bones, bypassing the ear canal. Learn about its applications, such as hearing aids, implants, and musical instruments, and its history from ancient times to modern technology.
Blue Microphones is an American subsidiary of Logitech that designs and produces microphones, headphones, and other audio equipment. Founded in 1995 in Latvia, it is known for its USB microphones such as the Snowball and the Yeti.
