Audio microphones are designed for sound reception and recording applications (speech and music

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Video, audio, and multimedia chips are IC chips designed for video, audio, and multimedia applications

Audio amplifiers and preamplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier

Measurement microphones are most commonly condenser microphones, which convert sound pressure to an output that is then converted into a reading such as sound pressure level (SPL

Audio recorders / voice loggers are used to locate, retrieve, duplicate and/or distribute audio voice or data information from single system environments to large multi-channel networked systems

Audio mixers and consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals

Specialized audio equipment is used in specific industries such as the recording industry, and for specialized applications such as voice digitizing and analysis

Audio visual service providers design, integrate, and install multimedia equipment for corporate, production, and broadcasting applications

Audio headphones are small speakers worn over the ears to isolate sounds for the listener

Headsets are attachments for holding an earphone and transmitter to the user's head.

Multiconductor cables contain two or more conductors, each of which consists of a single wire or combination of wires. Cable shielding is placed around an insulated conductor or group of conductors to prevent electrostatic or electromagnetic interference between the enclosed wires and external fields.

Noise control products passively control vibrations or noise through absorption or dampening (e.g., mufflers, silencers or baffles).

Broadcasting, studio and theatrical equipment, supplies and services includes video production consoles, theatrical lighting, theatrical curtains, and related products and services.

Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement.
