Sound travels faster in a denser medium, so sound travels most rapidly in steel. However, since sound is a longitudinal wave it is medium dependent, meaning that a medium must be present. Since a vacuum is basically defined as a lack of medium, sound will not travel at all ('No one will he…
Hello again, The sounds are heard not just by their tones., but for some they feel the vibrations on the ground and some have the accute sense of smell. it would take me a long time to explain this...go to the local Library and read about it from raptors to todays eagles to the thrree toed sloth. Re…
The amplitude of a sound wave is the pressure of the medium at a given point.
sound waves are the vibrations that occur in a material as a sound passes through it.
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. An…
soundyes sound travel in a straight line
What Sound Looks LikeThe answer is yes and no. If you drew a line from the source of a sound to where you were when you perceived it, it would appear to be a line. However, upon further analysis (the depth of that depending on the sound you are looki…
Sound travels through liquids like it travels through air. It is propageted by the collision of particles.
A buzzer is any mechanical, electromechanical, electronic, etc.
device designed to produce a buzzing sound or vibration when
activated. Some examples are:
joy buzzer, a mechanical device used for practical jokes that
is held in the palm and activated when the jokester shakes hands,
causing an unpl…
Waves transfer energy. Energy is the ability to do work or cause change. A wave is temporary in other words the waves don't last long. Waves always travel through a medium. The mediums can be solid, liquid, or gas. All the waves that need a medium to transfer energy are called mechanical waves. Ther…
For all practical purposes they are equal.
OvertonesAre known as: Overtones
Same way as it traverses in air. That is, as longitudinal waves. Compression and rarefaction
Sound is a longitudinal pressure wave of audible sound. It is a series of sound pressure waves that moves through air or other materials. These sound waves are created by the vibration of some object.
sound waves are compression waves, or longitudinal waves. sounds that we hear are actually just compressions and rarefactions of air particles, meaning the air particles move closer together for a time period then spread apart farther then they normally would rarefaction)
That depends what aspect of sound you want to measure: its speed, wavelength, intensity, etc.
You need an oscilloscope and the knowledge to use it. A frequency generator is useful to calibrate the scope.
the different types of sound are Analog and Digital.
Are known as: Overtones
because if there was no sound we couldn't hear anything !!!!!!!!!!
Desday;Communication, navigation and medical sometimes(killing bacteria, I think) these are main there are a few more.
sound waves are created by producing the vibrations in air
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.
No. Sound transmits by waves through matter/particles.
Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went. Doing this many times over and over, one can map out the ocean floor, and if the sound wave comes back relatively fast, that means there is so…
Sound travels in curved lines originating from the original source of the sound sort of like this ^
The Doppler effect.
Temperature will affect the strength of air particle interactions (an elastic property). The lower the temperature, the easier it is for the sound to travel through the air.
The four basic wave interactions are: wavelength, trough, crest, and amplitude.
No, it isn't harmful at its standard characteristics of operation.
Sound was NOT invented, it always existed. It is a pressure wave in
air and has been around at elast since the Earth's atmosphere was
formed. It was somewhat longer before there was anything with ears
or other sensors to hear it, however.
no. in space, sound waves can not travel. so there is no sound. only if you had a space suit you can hear things from other people with one
The higher the frequency, the higher the pitch. The lower the frequency, the lower the pitch.
Sound is the shape of the sound wave.
Not influenced by, is.
Another way of saying that is "The shape of a sound wave affects how rough or smooth that sound sounds".
For example: a pure sine wave (which looks similar to a capital letter "S" lying on its side) sounds smooth whilst a pure square wa…
It is the intensity of the sound wave. There is however a big difference between sound intensity and loudness. Loudness is measured with a scale called the Decibal scale , which is abbreviated as db in many cases. Your typical rock concert can hit db levels of 125db, and a typical iPod tops out at a…
Reverberation happens when reflections of a sound joins up with the original sound, so it seems prolonged. A reverberation is created from the reflecting surface when a sound is produced in an enclosed space causing a large number of echoes to build up and then slowly decay. Scroll down to related l…
pitch is the measurment of how high or low a sound is on a musical scale using notes, such as E, Eb, D, Db, C, etc.
Sounds are vibrations that spread equally in all directions unless they are directed. Because they can distort or even cancel other vibrations, it is possible to have a point in a noisy room where no sound at all would be heard. A whip makes a cracking sound because its tip moves faster than the sp…
Yes, it affects the density of air and thus the speed of sound in
A sound wave is a mechanical wave. The mechanical energy of the wave is transferred into the medium in which it is going to travel, and that medium carries it.
Desday;Its a vibration that starts in your voice box(or other source) and then travels through air as molecules and then someone hear…
No. Sound waves require air to move.
Sound is vibration transmitted through a solid, liquid, or gas.
To see sound waves as longitudinal waves in air moving, scroll down to related links and look at "Longitudinal wave - Wikipedia".
By frequency, wavelength, period, ect..
Frogs and Toads have an external eardrum called the tympanun but the ear does not have an external structure that protrudes like a human or dog. The eardrum is just behind each eye. This connects the sound to the hearing structures inside. These eardrums are sometimes difficult to see. Frog communic…
If the high frequency sound is within hearing range, you can hear it as a high-pitched sound. If it's out of the hearing range you can't hear it, of course.
Our ear drums with the ear/brain system are moved only by sound pressure motions. The sound pressure is the effect, but the sound power (sound intensity) of the source is the cause.The anwer is not so easy like it looks. Scroll down to related links and look at "Subjectivly perceived loudness ".
Pitch is the frequency at which an object vibrates to create a sound. A tuning fork, for example, that vibrates 440 times a second will produce a perfect "A" note. It is these predetermined levels of frequencies that pitch is categorized into the twelve chromatic musical tones.
Scroll down to related links and look for "Closed or Gedackt Organ Pipes - Wikipedia". Organ builders still tend to use feet rather than metres when dealing with organ pipe length and tone e.g. an 8 foot pitched pipe is the same pitch as a piano, and is called '8 foot' because the longest pipe of th…
okay whoever said that mass affected pitch is just stupid....Frequency and amplitude affect pitch
Waves transmit energy.
Sound waves travel faster through liquids than through gases because of the higher density of molecules in liquid.
The energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy. In fact, these two are equal, potential en…
ultrasonic means their frequency is too high for us to hear, infrasonic means their frequency is too low for us to hear. This is analogous to the electromagnetic spectrum, where ultraviolet light has too high a frequency for us to see, and infra-red light has too low a frequency for us to see.

Middle C is C4 with a frequency f = 261,626 Hz. We asume the temperature of 20 degrees Celsius or 68 degrees Fahrenheit where the speed of sound is 343 meters per second. The wavelength in air lambda is the speed of sound c divided by frequency f.
The wavelength lambda of middle C is 343 / 261,626 …
Sound causes vibrations in waves that pass through a medium.
In audio signal processing and acoustics, an echo (plural
echoes) is a reflection of sound, arriving at the listener some
time after the direct sound. Typical examples are the echo produced
by the bottom of a well, by a building, or by the walls of an
enclosed room. A true echo is a single reflectio…
Sound travels in a mechanical wave.
The number of waves that passes through a fixed point at a certain time
Sound travels via particle-to-particle vibrations around a mean
position; this means that the more particles there are, the better
the sound travels. Therefore, sound travels faster through iron
than through water or air. Sound travels through iron roughly 15
times faster than through air. The more …
This is called the Doppler Effect, a physics phenomenon that makes the sound of an approaching siren in an ambulance appear to be higher pitched as well as louder, but starts to immediately drop in intensity and pitch as it moves away from you. This is due to the apparent "compression" of the waves …

That depends largely on how close you are.
C. at LEAST 16.6 meters in front of the reflecting surface
Forget the A-weighting filter to measure in dBA. In vacuum (that means no surrounding medium) there is no transportation of sound possible. So there will be no sound level.
Sound comes from vibrations that travel through the air.
THERE ARE MANY TYPES OF NOISE SUCH AS SOFT ,HARD,POLITE etc

The act of applying sound energy to agitate particles is called
Sonication. It is used for many different purposes of study.
This is called the Doppler effect. A sound-producing object coming closer will sound louder than a sound-producing object moving away. The speed of this moving object effects how much this is noticeable.See link in the discussion area.
The Auditorium must be provided with special types of planning so that it can absorb sound
Not Your Personal Army
We know that sound (an acoustic wave) is mechanical energy that travels in waves. These waves require a medium to move through. Fluids (like a liquid, gas or plasma) and solids will conduct sound, and the energy of the wave is transferred into the medium in order for it to travel. The mechanical wav…
Commercially sold television receivers have always included a circuit for sound. Historically, the first successful transmission of synchronized sound and video took place on 13 June, 1925 when Charles Francis Jenkins sent a 48 line mechanical system image of film and sound five miles in a test tra…

Carpet and foam are great for absorbing sound in large areas.
Sound is a form of wave. Hence it is not considered a matter.
Well, it has to follow the inverse square law, so that as
distance increases, the sound intensity drops by the square of the
proportionate change in distance. The intensity will be 1/16 at 4
times the distance.
Sound is measured in decibels
Cleaning was one of the earliest industrial applications of
ultrasonics. Objects to be cleaned are placed in a bath of fluid
which is violently agitated by a number of ultrasonic transducers.
The fluid may be water or solvent based, depending on the
application. Traditionally the transduce…
There is no digital sound. Sound is analog because our ears are analog. You can store the sound information in a digital format which makes it easy to reproduce and copy without any loss. But at the end the sound in the air is analog.
Pretty much but it's not always off the ocean bottom. Sonar sends out a spherical "ping" it then receives pieces of the sphere back at different times based on when it hit something. It knows it's not the source as the pitch of the ping changes upon contact with a solid object. To gauge depth…
Yes, a sound wave is a mechanical wave. This is because sound waves need the medium of air to travel through.

Sounds are nothing more than tiny shaking movements of the air. Sounds are made when a material vibrates.Fast vibrations make a high sound, and slow vibrations make a low sound.Large vibrations make a loud sound, and small vibrations make a quieter sound.Plucking, blowing, shaking, beating or scrap…
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure.

Sound itself is always analog, though the quality varies. Things on a a computer, iPod, TV, etc. are represented and transmitted digitally, but it is converted back to analog before it gets to the speakers. An example of analog sound storage would be a record player. While both are voltage, digital …
Sound Waves are created by vibrations, even air too!
Because waves, such as sound, need to travel through a medium, whether it be water, air, etc. Since in empty space, there is no air, therefore there is no medium to travel in, so sound cannot travel.
