A microphone, colloquially called a mic or mike, is a device – a transducer – that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic sensors or knock sensors.
Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments. This effect is often created using a technique known as dummy head recording, wherein a mannequin head is fitted with a microphone in each ear. Binaural recording is intended for replay using headphones and will not translate properly over stereo speakers. This idea of a three-dimensional or "internal" form of sound has also translated into useful advancement of technology in many things such as stethoscopes creating "in-head" acoustics and IMAX movies being able to create a three-dimensional acoustic experience.

Phantom power, in the context of professional audio equipment, is DC electric power transmitted through microphone cables to operate microphones that contain active electronic circuitry. It is best known as a convenient power source for condenser microphones, though many active direct boxes also use it. The technique is also used in other applications where power supply and signal communication take place over the same wires.

Spill is the occurrence in sound recording and live sound mixing whereby sound is picked up by a microphone from a source other than that which is intended. Spill is usually seen as a problem, and various steps are taken to avoid it or reduce it. In some styles of music, such as orchestral music, jazz, and blues, it is more likely to be accepted or even seen as desirable.
The Sensor Observation Service (SOS) is a web service to query real-time sensor data and sensor data time series and is part of the Sensor Web.

Joachim Wetzel. Wetzel who was a trained radio engineer with a master craftsman's certificate, founded a small workshop in his parent’s house in Leipzig in late 1945 when he returned home after a brief war imprisonment period. At that time, Wetzel was particularly interested in the development and construction of reel tape recorders, condenser microphones and electrostatic tweeters. Later, after the company was running successfully, he opened a larger workshop in 16 Lindenstrasse, Leipzig. This is where the first condenser microphones were produced. He developed his own capsules in the style of Neumann M7, which were also supplied to other microphone manufacturers like Thiele and Adler. From 1960 on, Joachim Wetzel only manufactured microphones in his workshop, although he also provided repair services for other microphone manufacturers, so it’s possible to find RFT, ERWA or Neumman microphones that have Joachim Wetzel stickers, meaning that were serviced by him. Over the years he continued to manage his repair workshop, maintaining and servicing microphones, but also TV sets and cassette decks until shortly before his death in May 1989.
