Sound level Lp = 64 dBSPL equals what sound pressure p (rms)? The sound pressure is: 0.0317 pascals (Pa) = 31.7 millipascals (mPa) The reference sound pressure is: p0 = 20 μPa = 2 · 10-5 Pa (0 dB) The "sound pressure amplitude" is 1.414 larger than the rms value of the sound pressure, that means 44.8 mPa. Amplitude means always the peak value. There is an easy to use calculator. Scroll down to related links and look at "Conversion of sound units (levels)".

What instrument measures the amplitude of sound?

An oscilloscope measures electrical signal amplitude andwavelength. A decibel or sound-level meter. A cheap one is available at yourlocal Walmart for about $20 located in the car audio section. Ifnot instore, online. They make much better ones, but if you arelooking to just get a rough idea, this (MORE)

How is sound related to the amplitude of the sound wave?

From a wave model perspective, the intensity of a sound (i.e. its "loudness") is dependent on the amount of energy that the sound wave carries. The energy of the wave is proportional to the amplitude, how far the wave goes up and down. Thus, the intensity of voice is dependent on how much force you (MORE)

How do amplitude and frequency affect sound?

The sound pressure amplitude tells about how loud the tone will be and the frequency (cycles per second) of the oscillation tells how high the sound of the tone will be. The amplitude gives the loudness of the tone: http://en.wikipedia.org/wiki/Loudness The frequency gives the pitch of the tone: ht (MORE)

What is the sound pressure at sea level?

There is no sound pressure, there is atmospheric pressure of 101.325 kPa equivalent to 760 mmHg (torr), 29.92 inHg or 14.696 PSI.. The sound pressure is the local pressure deviation from the ambient atmospheric pressure caused by a sound wave.

Dba sound level vacuum?

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.

How is the intensity level of sound measured?

The acoustic intensity (energy) level is measured in decibels (dB). Your ear drums and microphone diaphragms are moved by sound pressure only. Also the SPL meters (sound pressure level meters) care about the sound pressure level.

The amplitude of a sound is measured in?

The amplitude of sound is measured in bells, though, more commonly, decibels. 1 decibel is the faintest whisper and 10 is the equivalent of a front row rock concert (or something along those lines).

Why sound is measured in db?

Because from the threshold of hearing with a sound pressure p = 20 µPa = 0.00002 Pascal to the threshold of pain with a sound pressure p = 150 pascals, there is a large range. So we set 0.0002 Pa = 0 dB as the reference pressure and 150 Pa = 137.5 Pa and we have not so large numbers. Decibels (dB (MORE)

Can you produce sound in vacuum?

No, you can not produce sound in a vacuum. Sound wave needs medium (for example air) to travel unlike electromagnetic wave which can travel through empty space.actually, sound wave does not propagate itself rather it needs a medium by which sound particle can transfer there energy from one place to (MORE)

Sound pressure levels comparison?

Comparison of Sound Pressure and Sound Intensity Levels.. Scroll down to related links and look at "Comparison of Sound Pressure and Sound Intensity Levels".

What is is the intensity of a sound that has an intensity level of 50 dB?

Better think of the sound pressure, when you are listening. Sound pressure moves your ears and the diaphragm of the microphones.. The sound intensity is very small. The level of 50 dB is equal to 0.0000001 W/m 2 acoustic intensity.. Scroll down to related links and look at "Conversion of sound un (MORE)

A sound waves amplitude corresponds to the sounds what?

Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: (MORE)

What do you use to measure the amplitude of sound?

A sound level meter would be used to measure sound level, and theunit is in decibels, dB. You could also measure it with amicrophone and oscilloscope, provided you could calibrate themagainst standard instruments.

How are sound intensity levels measured?

Your ears and the sound pressure level meter "measure" the sound pressure of a sound wave. Sound intensity is measured in watts per square meter. Note: Sound power (sound intensity) is the cause - and the sound pressure is the effect . The effect is of particular interest to the sound engineer.

How is sound level measured. At what level does sound become noise?

Sound level is measured in decibels (dB) by a sound pressure level meter (SPL meter). There isn't really a specific level at which "sound" becomes "noise." "Noise" is a somewhat subjective term for "sound that I do not want to hear"; for example, if rap music is at all audible, I personally consi (MORE)

Do loud sounds have a high amplitude?

Yes, amplitude is the maximum height from the undisturbed position of a wave to the crest or trough of a wave. A loud sound wil have a higher amplitude than a quiet sound.

What db has no sound?

dB is a logarithmic scale, so the answer, basically, is negative infinity.\n dB is a logarithmic scale, so the answer, basically, is negative infinity.\n dB is a logarithmic scale, so the answer, basically, is negative infinity.\n dB is a logarithmic scale, so the answer, basically, is negative i (MORE)

How are amplitude and frequency related to sound?

These two qualities are not directly related to each other. The amplitude of a sound wave is related to volume. The larger the amplitude the louder the sound. The frequency of a sound wave is pitch. The higher the frequency the higher the pitch.

What characteristic of sound is determined by amplitude?

The strength or volume of sound. By increasing the amplitude you enlargens the energy because the difference between peak negative and peak positive voltage in the waveform gets bigger. One use positive and negative voltage so that a loudspeaker can Push and Pull the membrane. Amplitude is the di (MORE)

Your perception of the amplitude of a sound wave is?

The amplitude of a sound wave is a measure of the distance between the rest position and the maximum displacement of the particle from its rest position. It is equal to half the total displacement of a vibrating particle.

What unit is used to measure the amplitude of a sound wave?

Sound wave amplitude is usually measured indirectly by measuringaccoustic pressure in decibels. Decibels is a ratio, so it has nounit. . +++ . To expand that, the linear unit of amplitude, the sound'spressure level, is the µPa (microPascal) but in acoustics it isnormal to use the deciBel (dB), (MORE)

Is a sound that measures 100-dB ten times louder than a 10-dB?

No. decibel (dB) is a logarithmic scale. Every time the decibels increase by 10 (10 more, not 10 times as much), the sound will get 10 times louder. For example, From 0 dB to 10 dB, or from -5 dB to +5 dB, or from 100 dB to 110 dB, will each increase the loudness by a factor of 10.

When the loudness of a sound and amplitude of a sound increases the amplitude of the sound produced will be?

The loudness of a sound is the same thing as the overall amplitude of a sound. When measuring sound, in general, you have pitch (frequency) and tone (amplitude, the measure of loudness). So, if you increase the amplitude of a sound wave pattern, you increase the overall intensity of the sound (the e (MORE)

What is the unit for measuring the amplitude of a sound?

That would be the 'Bel', a unit of sound amplitude named afterAlexander Graham Bell, the inventor who studied sound in order tohelp deaf people. Unfortunately, a Bel was a very large amount of sound - close tothe loudness of a jet taking off. As a result, much later, a tenthof a Bel came into commo (MORE)

What is an amplitude of a sound?

Amplitude is typically represented as being the "height" of a sound wave. A sound that is louder will have a greater amplitude than a quieter sound.

What kind of sound waves do vacuums produce?

The vacuum does not produce sound waves nor, can sound waves travel through them. A sound wave needs something to travel on/through, such as air. A vacuum doesn't contain any particles required for sound waves.
