Sound is vibration, as perceived by the sense of hearing. We usually hear vibrations that travel through air, but sound can also travel through gases, liquids and solids. It cannot travel through a vacuum (such as exists in outer space). When the vibrations reach our ears, they are converted into nerve impulses that are sent to our brains, allowing us to perceive the sound. In more technical language, sound "is an alternation in pressure, particle displacement, or particle velocity propagated in an elastic material" (Olson 1957 ...

The frequency range of sound audible to humans is approximately between 20 and 20,000 Hz. This range varies by individual and generally shrinks with age. It is also an uneven curve - sounds near 3,500 Hz are often perceived as louder than a sound with the same amplitude at a much lower or higher frequency. Above and below this range are ultrasound and infrasound, respectively. The amplitude range of sound for humans has a lower limit of 0dBSPL, called the threshold of hearing. Sound is technically at its upper limit at 194.09 dB. A ...

Sound power or acoustic power Pac is a measure of sonic energy E per time t unit. It is measured in watts, or sound intensity I times area A: The measure of a ratio of two sound powers is where P1, P0 are the sound powers. The sound power level PWL, LW, or LPac of a source is expressed in decibels (dB) and is equal to 10 times the logarithm to the base 10 of the ratio of the sound power of the source to a refere ...

Albemarle Sound is a body of generally fresh water on the coast of North Carolina in the United States located at the confluence of a group of rivers, including the Chowan and Roanoke. It is separated from the Atlantic Ocean by the Outer Banks, a long barrier peninsula upon which the town of Kitty Hawk is located, at the eastern edge of the sound. Roanoke Island is situated at the southeastern corner of the sound, where it connects to Pamlico Sound. The sound (see definition at that entry< ...

Anahata Sounds

Anahata sounds are the mystic sounds heard by the Yogin during his meditation. It is a sign of the purification of Nadis. Some students can clearly hear it through any one of the ears and some by both the ears. There are loud as well as subtle sounds.

From "Kundalini Yoga" by Sri Swami Sivananda

Sound pressure p (or acoustic pressure) is the measurement in pascals of the root mean square (RMS) pressure deviation (from atmospheric pressure) caused by a sound wave passing through a fixed point. The symbol for pressure is the lower case p. The upper case P is the symbol for power. This is often misprinted. The unit is pascal (symbol: Pa) and that is equal to a force (F) of one newton (1 N) applied ov ...

Wall of Sound is a phrase used to describe the effect created by the music production techniques of legendary record producer Phil Spector. Wall of Sound - Description. During the Wall of Sound era, Spector gathered large orchestras of musicians (even for instruments not generally used for ensemble playing such as the electric guitar) playing orchestrated parts for a fuller sound. Not so well known is that at the heart of the Wall of Sound was an echo chamber – a basement room fitted with microphon ...

The sound intensity, I, (acoustic intensity) is defined as the sound power Pac per unit area A. The usual context is the measurement of sound intensity in the air at a listener's location[1]. The SI units are W/m2 (watts per square metre). For a spherical sound source, the intensity as a function of distance r is: The sound intensity I in W/m2 of a plane p ...

For the album, see Sound Affects. Sound effects or audio effects are artificially created or enhanced sounds, or sound processes used to emphasize artistic or other content of movies, video games, music, or other media. In motion picture and television production, a sound effect is a sound recorded and presented to make a specific storytelling or creative point without the use of dialogue or music. The term often refers to a process applied to a recording, without necessarily referring to the recordi ...

sound: Shabda. As the darshana, or "seeing," of the Divine is a central article of faith for Hindus, similarly, hearing the Divine is spiritually indispensable. The ears are a center of many nadis connected to inner organs of perception. Gurus may when imparting initiation whisper in the ear of disciples to stimulate these centers and give a greater effect to their instructions.

During temple puja, bells ring loudly, drums resound, conches and woodwinds blare to awaken worshipers from routine states of consciousness.

Meditation on inner sound, called nada-anusandhana, is an essential yoga practice. Listening to the Vedas or other scripture is a mystical process. Traditional music is revered as the nectar of the Divine.

See: Aum, nada, Siva consciousness.

These are sounds, calls, or audible signals made by any one species to its own or any other species, establishing boundaries so like or unlike species will not transgress those boundaries. Male baboons make sounds heard for miles by other baboons, communicating to those other male baboons, the territory of that male baboon. The strength, volume, and timbre, inherent in that "call", determine whether or not rival ma ...

Hypersonic Sound is sound that propagates in a beam like light rather than propagating in all directions like sound usually does. This means it's only detectable in a narrow area in front of the emitter. When an observer steps out of the beam of sound it appears as if the sound is no longer being emitted. Hypersonic sound actually travels at ultrasonic frequencies, which are frequencies that are above what humans ears can detect. It's because of this that Hypersonic sound travels in a straight line rather than spreading out lik ...
