Binaural and Holophonic Sound

Binaural Recording

A Binaural Recording is a recording that is made usually by special Microphone arrangement.The usual method is by the use of a dummy head.In this method,a dummy head is placed and two microphones are placed exactly where our ears would be,precisely.Using this arrangement,recordings are made and the information about the position of the sound source is also embedded in the recording.As a result,the output is a very-realistic,immersive experience,that makes the user feel as though the sound really is emitted from the exact spot. However,there are certain limitations to this method:

1)You need Headphones to Listen to the recordings

2)Binaural Recordings,though somewhat realistic,has better subtitutions

Holophonic Recordings

A Holophonic Recording is similar to a Binaural recording,except that an inaudible reference signal is passed through the recording,that adds perception of Complete Depth.Unlike Binaural Recordings,Holophonic Recordings sound extremely realistic,some people even claim that they smell sulphur when they hear a match stick light!!!

This technique was developed in 1980 by Hugo Zuccarelli.It is similar to the way in which a typical Hologram Label is made,except that Sound signals are used.Some researchers cite that even some hearing-disabled people can hear holophonic sound!

Though Holophonic sound is gaining popularity among Professional Artists,it needs more light.Just like a Binaural recording,Holophonics sound best when heard through Headphones.
