The wonder of nature . . . By Kirsten Nour Namsk
Partly because we haven’t had the interest of finding out, partly because some of the sounds are on a sound-wave the human ear can not hear. More so . . .the animals easy understand the human . . . it’s the human who don’t understand
Sound Waves
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s.
Sound Field Analysis Based on Analytical Beamforming
The plane wave decomposition is an efficient analysis tool for multidimensional fields, particularly well fitted to the description of sound fields, whether these ones are continuous or discrete, obtained by a microphone array.
Ultrasonic sound wave device kills algae in swimming pools without
(NewsTarget) A swimming pool or pond in your back yard, while a nice feature, usually involves using a lot of harsh chemicals to control algae, but an ultrasonic device by LG Sound stands to change that. The new device is called the LG
VELOCITY AND WAVELENGTH
Sound waves propagate through the air at approximately 343 m/s,or about 767 miles per hour.At this peed, the sound waves travel one mile in about five seconds. Picture a sound wave, as in the diagram,with a sine curve drawn next to
The frequency of a sound wave
An object vibrating more slowly produces lower frequency sound waves. A high frequency sound wave is heard by the human ear as a high pitch,or a high note, while a low frequency wave is heard as a low pitched sound.
Calculations Involving the Doppler Effect
To solve this problem, try to picture in your mind the sound waves being emitted from the train whistle. We know the velocity of sound, 343 m/s, and we know the frequency of the waves, 250 Hz. From this we can calculate the wavelength:
THE DOPPLER EFFECT EXPLAINED
Picture in your mind the sound waves being emitted from the train whistle and expanding outward as ever enlarging spheres. When the first wave is emitted, it begins to expand from the point at which it was emitted.
Using Sound Waves to Create Antigravity
By applying a continuous resonant(600Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; I was able to control levitation and movement in all 3 (x,y,z) axis of the ambient space.

The diagram below depicts a sound wave created by a tuning fork and propagated Sound is indeed a longitudinal wave with compressions and rarefactions.
The Physics Classroom
The nature of sound as a longitudinal, mechanical pressure wave is explained and the properties of sound are discussed. Wave principles of resonance and
Sound Wave Applet
Notice how the frequency of the sound changes when the source is moving and notice how the waves collect into a Mach wave when the object moves faster than

A holistic approach to wellness, whose purpose is to bring you back into a state of harmony and balance through the use of sound frequencies.
Refraction of Sound Waves
Instead the wave speed changes gradually over a given distance. The speed of a sound wave in air depends on the temperature (c=331 + 0.6 T) where T is the
