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

Abstract
A numerical study has been carried out to investigate the full flow path and aerodynamic characteristics of a hypersonic vehicle ata 7.0 free stream Mach number. Results indicate that the inlet started and unstarted operations have remarkable effects on the flow patternof the full flow path. When the inlet operates in a started mode, the transverse pressure gradient generated by the forebody alters theair captured characteristics and the entering flow quality of the inlet. Furthermore, the expansion proces ....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

Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, as they provide significant weight-savings while maintaining comparable mechanical properties. Gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800°C). The purpose of this investigation is aimed at evaluating the potential of a gamma titanium aluminide alloy with nominal co ....etc

When the intensity of sound exceeds certain intensity, the alarm is
triggered and the siren begins to operate. The speaker beeps and the flasher
(light) flashes. Thus the owner of the residence is alerted when an intruder comes.

The functional block diagram includes
-MICROPHONE
-AMPLIFIER
-LATCH
-OSCILLATOR
-FLASHER
-SPEAKER

a 600O unidirectional moving coil microphone is used. LM386 CMOS operational amplifier was the main component in the amplifier. It had a gain of 200. The amplifier then passes it on to the latch section of t ....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
