Sound Waves

Parent Category: Physics
Sound waves are a mechanical oscillation of pressure. It is a series of vibrations that can be heard.
This is an example of the Doppler effect.Sound is composed of waves.A particular vibration produces a sound wave with a particular wavelength.When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency.When the...
How about this: What's inside the box? How Sound Wave Intensity  changes in a speaker box to outside.
The property is amplitude. Sound waves are pressure waves, and the higher the amplitude, the higher the pressure created, and the louder the sound is.
Receiving sound waves is the process by which sound travels in form  of waves and is received by our eardrums to be heard.
The term "duration" applies to the length of sounds. Duration and  sound pressure level are the determiners of a sound's loudness.
What we perceive as "sound" is in fact a neural reaction to changes  in air compression that our brains interpret as "sound". Air is  compressed by some mechanical action (such as a speaker moving  inwards and outwards), and the outer ear acts as a bit of a lens to  capture and guide these...
Do to there massive size ears
4mm / (1.54mm/us) = 1 sound wave every 2.5974us. 1,000,000us per second. 1,000,000/2.5974 = [385,000Hz] With proper sigfigs = 4 x 10^5 (if the values given here are exact)
curtains, wardrobes, cushions, clothes
All "waves" are energy. In this case, music is a tremendously  complex series of waves caused by air compression of differing  frequencies, phase, and amplitude. But they are still waves, caused  by movement of the air - basic physics tells you that moving air  has force (however small) and...
Neither - they are both the same amplitude, which is typically  interpreted as "power". A larger amplitude will have greater  "power" in that it will sound "louder".
Sound waves are known as longitudinal waves.
Unlike electromagnetic waves such as radio and television or light  which can travel through the vacuum of space, sound waves travel by  the compression and decompression of molecules in the medium  through which they are passing. The medium must be compressible,  whether it be gas, liquid or...
Sound waves are the means by which echolocation works. First,  sounds are transmitted by an organism or a device. Sound waves will  "bounce" off of objects and reflect back towards the source (in  fact, in many different directions). Echolocation works by  listening for these echoes and their...
 air density (and thus air pressure, temperature, wind and  relative humidity); and  motion of the source (causes Doppler effect).  
Sound energy is a form of mechanical energy, and is produced when  an object vibrates. The sound vibrations cause waves of pressure  that travel through air, water, wood, or metal.
The energy in a sound wave is related how the air pressure changes  as the wave move through the air. A moving object such as a  vibrating drum head causes pressure disturbances in the air, which  travel away from the object. The higher the pressure difference  (between maximum and the 'normal'...
A sonographer uses ultrasound to image  body organs.
Amplitude. As the amplitude of the sound wave increases, the sound  becomes louder.
Ultrasound can be used to image abdominal organs. There is an  article on the website radiologyinfo dot org. But I cannot figure  how to post the link, here.
Frequency (measured in Hertz, which is cycles per second). Higher  frequency, or more cycles (or oscillations) per second, will sound  as a higher pitch.
because sound travels pretty slow. thats why if your in the very  back at a rock concert, and you see the drummer hit a drum, and you  hear the drum a half a second or so later. in marching band, you  want the sound to line up for the audience. to achieve this, listen  back, and center. usually...
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
.. because the earth sampak to the moon :)) .. HAHAHAHA
Sound is a compression or rarefication of air. That compression is measured in frequency (Hertz) or cycles per sec . 440 Hertz is A or "Concert Pitch"
Sound waves are everywhere. You could find them in such places like the television, or the radio, or even instruments. The vibration of a string on a guitar or a reed on a clarinet, produces sound waves.
Grounding would be more appropriate
it travels through rock quickest even if they are both solids eking
A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.
Sound waves are described as pressure waves because the sound we  hear is caused by the variations in air pressure. Compression and  ratification of air make the eardrum move.
An antenna is specifically designed to "pick up" electromagnetic waves.These are typically  amplified and converted to electronic signals in some sort of circuit. That circuit can then provide a signal to another device to produce output.  This happens with a radio when the antenna gets...
No, there is no sound in space because there is no air. Without air sound will not travel anywhere. Sound is created by a wave moving. For a wave to move, it needs a medium. Sound travels in air or water. There is no air or water in the vacuum of space. Believe it or not...this is actually false...
To create a shock-wave you need to have some form of medium to support it. As space is well neigh a perfect vacuum, No.
Has to be completely closed area no air could be flowing in or out so cover up all the air holes as good as you can and your good
The eardrum vibrates when sound waves reach it.
A sound wave in the air is called a Longitudinal wave.
The amplitude is the maximum amount it sways from the neutral  position. If it oscillates about zero, then it would vary from a  value of +A to -A, where A is the maximum Amplitude. The units of A  will be determined by the type of wave.
Because the sound waves have no where to go and bounce off your hand right back to your ear.
Scientists do not need perfect pitch to analyse sounds because they use instruments to detect and assess the noise.
Beats are the direct result of the interference that is caused by the difference in frequencies of two sound waves. 
by using gadgets or other thing in music..
Longitudnial waves (or pressure waves).
Of the four materials, wire will carry the sound best because it is the most dense.
From what part of the body,And then again there is tone attitudeand emotion too
they are different by the way they behave and the way it is different is one behaves like they should and the other one behaves bad.
The fingerprint of sound can come in pulsation and percussion
Particles, e.g gas particles in air, because sound travels through the vibration of particles. Sound waves cannot travel in a vacuum, as there are no particles.
Space or a vacuum as there are no atoms...
Sound wave is is generated by a vibrating object.Whereas, seismic wave is the vibration generated by an earthquake or explosion.
The sound wave is actually a pressure wave. The air molecules move  together and then farther apart, creating volumes which alternate  between (slightly greater than normal pressure) and (slightly less  than the normal pressure). A volume, at a specific pressure, can be  expressed as energy ...
its because the sound waves travel faster in air..... and also recommended the waves
As you may know, the sound energy is basically a wave or many waves  traveling through the air( or anything that is not a void ) and  those waves carry energy not matter. the sound waves or sound  energy is a part of kinetic energy because the energy is not  waiting to be unleashed, in fact it's...
No.  Sound energy is mechanical, it is associated with the movement of atoms.
Sound waves (in gas, liquid and sometimes in solid) are longitudinal, not transversal. They cannot be polarised.Sound waves (sometimes in solid) are always "polarised" as the medium must move in a single plane perpendicular to the direction of travel.
Yes, for any traveling wave: (frequency) x (wavelength) = velocity.  For a given medium (such as air) and temperature and air pressure,  the velocity will be constant, so as frequency decreases, then  wavelength will be longer so that the product of the two is equal  to the constant velocity.
There must be particles present for sound waves to travel. Sound travels by vibration, when one particle hits another. This is why there is no sound in a vacuum as no particles are present. Therefore, sound travels better within a space with a higher concentration of particles. For example, sound...
An osciloppe measures oscillations. Oscillations are vibrations. And vibrations are sound waves.
The frequency of the wave.f.
yes bcoz for different temperature we have different mediums.....
Naturally occurring sound waves are analog, although they can be digitized.
no, it's a mechanism for transmitting sound. and sound isn't limited to gas either. It can pass through solids (you can listen through a wall or a door) and through liquids (you can still hear when your ears are submerged in a bath or a pool)
They have a frequency of above 20,000Hz inaudible to human ear.
As long as it is not used manually in a destructive manner
it's not a fixated thing. there are different frequencies that are  called HERDs. So 10 HERDs is a really long wave and carries very  little energy, 100,000 HERDs would actually carry so much energy  that you could actually feel them, and they are also extremely  short.
The wavelength is the length (distance) between two adjacent crests  (or troughs, or any other part of the wave which starts repeating).
width is just a change in frequency (distance between waves). volume or decibels is more of a change in amplitude (height of wave).
... are produced by an amplifier and a loudspeaker.
When you add two waveforms in a non-linear medium they produce sum and difference frequencies. So if you have a tuning fork and a piano string, you hear a difference frequency as an amplitude modulation on the basic tone - the tone appears to get louder and softer at regular intervals. So you tune...
Sound waves exhibit the same properties as most other waves, e.g. light or water. Sound waves stop forward motion when they are experience either total reflection or total absorption. A dramatic change in the density of material will cause significant reflection of sound and, in principle, you...
Yes, it never disappears
By vibarting an object, it would produce sound waves.
Consider the difference in sound between a large empty room thatonly has hard walls to reflect sound compared to a room withdifferent kind of furniture and curtains or drapes. An echo occurswhen sound (sound waves) reach a solid object that reflects thesound away and back to where it originated. If...
well some people may see the sound waves some people have a strangeability when its possible that the parts of the brain devoted tovision is small. my guess would be somewhat similar to likedaredevil the movie. when it rains he can see and when certainnoises happen the soundwaves move and causes him...
sound sounds like sound
In audio signal processing and acoustics, an echo (pluralechoes) is a reflection of sound, arriving at the listener sometime after the direct sound. Typical examples are the echo producedby the bottom of a well, by a building, or by the walls of anenclosed room. A true echo is a single reflection of...
logitudional waves travel by air particals they touchg each other and pass won the vibration
Sound waves cannot be digitised it can be transformed
