RECONSTRUCTION OF RECORDED SOUND
ABSTRACT
Bulk of recorded sound history the audio information was stored in mechanical media, such as a phonograph record or wax cylinder, via undulated surface incisions (grooves). The groovesâ„¢ shape and position can be reconstructed without mechanical contact by using precision optical metrology tools. The surface map thus obtained can be digitally processed further to remove noise artifacts due to damage and wear, and to convert the groove positional information into audio format. The viability of thi ....etc

ABSTRACT
Hypersonic sound technology from American Technology Corporation employs ultrasonic waves to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear. Hyper Sonic Sound is produced without the excess bag ....etc

There are many surround systems available in the market .They use different technologies for produce surround effect. Some Surround sound is based on using audio compression technology (for example Dolby ProLogic? or Digital AC-3?) to encode and deliver a multi-channel soundtrack, and audio decompression technology to decode the soundtrack for delivery on a surround sound 5-speaker setup. Additionally, virtual surround sound systems use 3D audio technology to create the illusion of five speakers emanating from a regular set of stere ....etc

Clap Switch
Sound operated switch using a simple transistor circuit
The operation is simple. Clap and the lamp turns on. Clap again and it turns off.
The electret microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bistable multivibrator change state at each signal. One of these transistors drives a heavier transistor which controls a lamp.

The Colour of Sound
Abstract
Where™s that noise coming from?. It™s a question we™ve often asked and one which would be easier to answer if we could ˜see™ sound. Our eyes can™t, so our brains are left to process the sounds reaching our ears and then triangulate an approximate location. And if something is hard to hear, we tilt our heads a little “ instinctively repositioning our ears to get better reception. Because our ears seldom have identical performance, we are often deceived over the exact locati ....etc

We are now entering the Third Age of reproduced sound. The monophonic era was the First Age, which lasted from the Edison's invention of the phonograph in 1877 until the 1950s. During those times, the goal was simply to reproduce the timbre of the original sound. No attempts were made to reproduce directional properties or spatial realism.

The stereo era was the Second Age. It was based on the inventions from the 1930s, reached the public in the mid-'50s, and has provided great listening pleasure for four decades. Stereo improved the reprodu ....etc
