Silent disco

A silent disco or silent rave is an event where people dance to music listened to on wireless headphones. Rather than using a speaker system, music is broadcast via a radio transmitter with the signal being picked up by wireless headphone receivers worn by the participants. Those without the headphones hear no music, giving the effect of a room full of people dancing to nothing. In the earliest days of silent discos, before 2005, there would be only one channel available to listen to music through. Over time, the technology moved along to where there were two, and later technology allowed (more…)

Noise-cancelling headphones

Noise-canceling headphones are helmets that reduce unwanted ambient noise through active noise control. This is different from passive headphones which, if they reduce ambient sounds, use techniques such as soundproofing. Noise canceling allows you to listen to audio without increasing the volume. It can also help a passenger to sleep in a noisy vehicle such as an airliner. In the aviation environment, noise-canceling headphones significantly increase the signal-to-noise ratio more than passive noise-canceling headsets or no headphones, making it easier to listen to important information such as safety announcements. Noise-canceling helmets can improve listening enough to completely compensate for the effect (more…)

In-ear monitor

In-ear monitors (IEMs) are devices used by musicians, audio engineers and audiophiles to listen to music or to hear a personal mix of vocals and stage instrumentation for live performance or recording studio mixing. They are often custom fitted for an individual’s ears to provide comfort and a high level of noise reduction from ambient surroundings.

A monitoring system is any system that provides a mix of audio sources to a performer on stage. Traditionally, monitors were loudspeakers placed on stage directed toward the performer (often called floor monitor speakers or wedges). Depending on the sophistication of the audio system, floor wedge (more…)

Headphone amplifier

A headphone amplifier is a low-powered audio amplifier designed particularly to drive headphones worn on or in the ears, instead of loudspeakers in speaker enclosures. Most commonly, headphone amplifiers are found embedded in electronic devices that have a headphone jack, such as integrated amplifiers, portable music players (e.g., iPods), and televisions. However, standalone units are used, especially in audiophile markets and in professional audio applications, such as music studios. Headphone amplifiers are available in consumer-grade models used by hi-fi enthusiasts and audiophiles and professional audio models, which are used in recording studios.

Consumer headphone amplifiers are commercially available separate devices, sold to (more…)

Crystal earpiece

A crystal earpiece is a type of piezoelectric earphone, producing sound using a piezoelectric crystal, a material that changes shape when electricity is applied to it. It is usually designed to plug into the user’s ear canal.

A crystal earpiece typically consists of a piezoelectric crystal with metal electrodes attached to each side, glued to a conical plastic diaphragm or sheet of metal, enclosed in a plastic housing. The piezoelectric material used in the earliest crystal earphones was Rochelle salt, but modern headphones use barium titanate, or less often quartz. When the audio signal is applied to the electrodes, the crystal leans (more…)

Headphones (or head-phones in the early days of telephony and radio) are a pair of small loudspeaker drivers worn on or around the head over a user’s ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, (more…)
