Sound is a disturbance of mechanical energy that propagates through matter as a wave. Sound is characterized by the properties of sound waves, which are frequency, wavelength, period, amplitude and velocity or speed.\n\nBy sound, we commonly mean the vibrations that travel through air and can be heard by humans. However, scientists and engineers use a wider definition of sound that includes low and high frequency vibrations in air that cannot be heard by humans, and vibrations that travel through all forms of matter, gases, liquids and solids. The matter that supports the sound is called the medium. Sound propagates as waves of alternating pressure, causing local regions of compression and rarefaction. Particles in the medium are displaced by the wave and oscillate. The scientific study of sound is called acoustics.\n\nNoise and sound often mean the same thing; but noise is often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a signal\n\nSound is perceived through the sense of hearing. Humans and many animals use their ears to hear sound, but loud sounds and low-frequency sounds can be perceived by other parts of the body through the sense of touch. Sounds are used in several ways, notably for communication through speech or, for example, music. Sound can also be used to acquire information about properties of the surrounding environment such as spatial characteristics and presence of other animals or objects. For example, bats use echolocation, ships and submarines use sonar, and humans can determine spatial information by the way in which they perceive sounds.\n\nThe speed at which sound travels depends on the medium through which the waves are passing, and is often quoted as a fundamental property of the material. In general, the speed of sound is proportional to the square root of the ratio of the stiffness of the medium and its density. Those physical properties and the speed of sound change with ambient conditions. For example, the speed of sound in air and other gases depends on temperature. In air, the speed of sound is approximately 345 ms-1, in water 1500 ms-1 and in a bar of steel 5000 ms-1.

Signal to Noise is the ratio of avg Power of signal to avg Power of noise expressed mathematically as:\nSNR(dB)= 10Log(signalPower/noisePower) = 20Log(signal Amplitude/noise Amplitude)\nwhere the Amplitude is the RMS amplitude.\n\nAlso of interest is the Dynamic Range. The dynamic range measures the ratio between noise and the greatest un-distorted signal on a channel.\n\nAnother interesting measurement is the THD - Total Harmonic Distortion. Which is measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental.\n\nAlot people always want to know the power of an amp, I have come to enjoy low power and less distorted music is much more pleasing.

Acoustics. Acoustics science's commercial applications usually revolve around designing things to have good acoustics such as concert halls, theaters, etc. Good acoustics means that the sound carries well and doesn't get muddled, even in the very last seat.

Sound Is Energy\n\nHome\nThe Energy\nBrass\nPercussion\nString\nWoodwind\nSuper Quiz\n\n \n\nTo enjoy all of our sound files download "RealPlayer" for free from the Internet.\nDid you know?\n\nHorn and woodwind players kiss their instruments? Watch one, next time, and you’ll see why! The position of the player’s mouth around the reed or mouthpiece is called "embouchure" which comes from the French word "boucher" meaning "to kiss".\n\nEnergy In The Air: How Sound Is Made \n\nCRASH! BANG! Did you hear that sound? It was made by air vibrating. The same is true for sounds made by musical instruments. The difference between NOISE and MUSIC is that musical sounds are organized into patterns that have pitch and rhythm. Noise is just random, disorganized sounds. Sounds are made and travel in the same way whether they are musical sounds or noise.\n\nA musical sound is called a tone, and is produced by air vibrating a certain number of times per second. These vibrations are called waves. These sound waves must be contained in some way so that the performer can control the loudness, quality of the tone, and how long it plays. Most musical instruments have a reed, a string, or some other device that creates sound waves when moved. Sounds are different because of harmonics, which are higher and quieter sounds mixed in. They are not heard separately, but add to the tone of the sound, making an oboe sound different from a trumpet or drum.\n\nThe number of times that a sound wave vibrates in a second is called its frequency. Scientists even have a name for how they measure the frequency of sounds. They measure it in cycles and call it hertz. High notes have a higher frequency than lower notes and this changes their shape. Different types of sound waves have different shapes. Look at these images to see what sound waves "look" like.\n\n\nFor the rest go to the site below.

According to webster's dictionary noise is loud, confused, or senseless shouting or outcry\nNoise also is one that lacks agreeable musical quality or is noticeably unpleasant b : any sound that is undesired or interferes with one's hearing of something c : an unwanted signal or a disturbance (as static or a variation of voltage) in an electronic device or instrument (as radio or television); broadly : a disturbance interfering with the operation of a usually mechanical device or system d : electromagnetic radiation (as light or radio waves) that is composed of several frequencies and that involves random changes in frequency or amplitude e : irrelevant or meaningless data or output occurring along with desired information\n\nThis to me is not definitive enough to describe a tree.  \nYes you can measure noise but "sound" seems to be a better description than noise for a tree falling (previous question)

To explain this, I would have to use many words, so here's a website to sum it up for you:\nhttp://electronics.howstuffworks.com/speaker.htm

The frequency of sound is the number of waves emitted by the source of sound.\n\nBut we judge the frequency of sound by the number waves falling in our ear drum.\n\nIf we were standing still, we will judge the actual frequency of the sound emitted by the speaker.\n\nIf we move toward the speaker, the number of waves that are falling in our ear drum is increased; the number is increased by a factor c+v/ c where c is the speed of sound and v is the speed of us toward the speaker.\n\nThe same thing happens if we are at rest and the speaker moves toward us. \n\nSuppose we move away from the speaker with the speed of sound, then we cannot hear the sound at all. If we move with a speed less than that of sound, it implies the speed of sound is more and as we are also moving we will hear only less number of waves. Thus the frequency is decreased.  This time the factor is c-v/v. \n\nThe same thing happens if we are at rest and the speaker moves away from us.\n\nThis effect is called Doppler effect.

It's used in music. It means the note is sharp.

Hi :-) ! I suppose you had better ask in the category "Entertainment and Music" if you have not done so already. I only know the terms in French, which are "contrepoint", "harmonie" and "fugue". In English, it might be the twelve tone technique. Maybe have a look on the links below. \n\nHope this helped a bit if it was indeed about music. Or was it for a poem or something else? Good luck!

To gain control = commandeer,\n\nbut to adjust the gain control= adjust the volume.

the state of a system in which an abnormally large vibration is produced in response to an external stimulus, occurring when the frequency of the stimulus is the same, or nearly the same, as the natural vibration frequency of the system.\n\nthis is whereby an object vibrates in the same frequency with another object, This is due to the energy transfer from one object to the other. \nreasonance occurs when one creates a vibration and the sorounding objects emit the same vibrations because of the frequency ernergy emmited.\n\nexample 1:\n\nturn your Hi Fi system to full blast in the house and notice the windows will start to vibrate(this is resonance you will be experiencing).\nexperiment 2:\n\ntake a speaker then plug it to your system then birng it closer to another speaker example is in this format =[(  )]= notice that the second speaker will emmit sound(coz of the vibration created dy the first speaker).\n\ninfact antenas use reasonance inorder to receive  waves(channels) \n\nalso you can read a reserch report on it below

The above are correct, but adagio has also life outside of music. It means slowly, but is no longer part of everyday speech. You can check for musical terms at\n\nwww.italian-language-study.org
