: a region in a material medium in which sound waves are being propagated.
What is the sound of microphone called?
However, there is always some portion of noise generated by the microphone itself – self-noise. Primarily this noise originates from a current running in the circuitry (so-called “shot noise” or “Poisson noise”). Also, thermal noise (or “Johnson noise”) is an issue; the higher temperature, the higher the noise.
What is far field sound?
The far field is defined as the region where the sound pressure and acoustic particle velocity are in phase, and where the sound pressure level decreases by 6 dB for each doubling of the distance from the source. Figure 2: The far field begins at approximately 1 wavelength away from the source.
What is a sound field speaker?
With a SoundField system, the sound is amplified into the entire room via speakers. To reduce any background noise, the person speaking wears a microphone and their voice is amplified to a comfortable and optimal level to ensure a clear signal.
What is Ambisonics used for?
Ambisonics is a method for recording, mixing and playing back three-dimensional 360-degree audio. It was invented in the 1970s but was never commercially adopted until recently with the development of the VR industry which requires 360° audio solutions.
What is a soundfield system?
Soundfield amplification systems are devices that amplify the teacher’s voice in the classroom. The teacher’s voice is able to be heard more easily over the background noise. Soundfield systems benefit all children in the classroom, including children with a hearing loss.

What is a free – field microphone?
Free-field microphones are commonly used for sound measurement in an anechoic chamber or far away from reflecting buildings, etc. Another area for free-field microphones is for general electroacoustic measurements like loudspeaker and microphone measurements.
What is the smallest voice recorder?
The smallest digital voice recorder is the Edic-mini Tiny+ B70, measuring 3756.15 mmᶟ (0.22 inᶟ) in volume, made by Telesystems (Russia).
What is function of the microphone in a telephone?
a worldwide system of communications using telephones. The microphone in one telephone converts sound waves into electrical signals that are transmitted along a telephone wire or by radio to one or more distant sets, the receivers of which reconvert the incoming signal into the original sound.
