- In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.

- The most basic characteristics of a sound wave are pitch, loudness and tone. A sound wave's frequency is experienced as the wave's pitch. The amplitude determines loudness or volume. The tone of a sound wave can be recognized by the regularity of its vibration.

What Is Sound? Frequency is the rate, or number of times per second, that a sound wave cycles from positive to negative to positive again. Frequency is measured in cycles per second, or hertz (Hz).f a sound has a lot of low-frequency energy, it has a lot of bass. The 250–4000 Hz frequency band, where humans hear best, is described as midrange. High-frequency energy beyond the midrange is called treble, and this adds crispness or brilliance to a sound.

sounder 1 sound 1. (sound) A type of longitudinal wave that originates as the vibration of a medium (such as a person's vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density.

Sound In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain. distinct use of the term sound from its use in physics is that in physiology and psychology, where the term refers to the subject of perception by the brain. The field of psychoacoustics is dedicated to such studies. The physical reception of sound in any hearing organism is limited to a range of frequencies.

Sound The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave.

Sound: Facts Sound vibration must travel through matter. This is typically air. When you say, Hello, to a friend, the air parts (called molecules) vibrate in small waves which travel to the friend and they hear the word Hello.. Sound can also travel through other matter.

Sound Sound is defined by ANSI/ASA S1.1-2013 as (a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.

Sound (geography) In geography, a sound is a large sea or ocean inlet larger than a bay, deeper than a bight, and wider than a fjord; or a narrow sea or ocean channel between two bodies of land (see also strait). There is little consistency in the use of sound in English-language place names. 1 Overview.

- The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause.But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.he energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass a … nd moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy.

Sound is a Pressure Wave Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it.

Sound is a Pressure Wave Sound is a Pressure Wave. Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport.

- Noise (electronics) In electronics, noise is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly as it is produced by several different effects.

- Since sound is a wave, we can relate the properties of sound to the properties of a wave. The basic properties of sound are: pitch, loudness and tone. Pitch. The frequency of a sound wave is what your ear understands as pitch. A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch. In Figure 1 sound A has a higher pitch than sound B. For instance, the chirp of a bird would have a high pitch, but the roar of a lion would have a low pitch.

What Is Sound? All sounds are vibrations traveling through the air as sound waves. Sound waves are caused by the vibrations of objects and radiate outward from their source in all directions. A vibrating object compresses the surrounding air molecules (squeezing them closer together) and then rarefies them (pulling them farther apart).

What are Sound Waves? - Definition, Types & Uses A sound wave's frequency is a number that tells you how many waves pass by each second. Frequency is measured in Hertz (Hz). So for example, 60 Hz, the frequency of most TVs, is 60 waves per second. Or in case of television, this means that the picture refreshes 60 times a second.
