A sound level meter would be used to measure sound level, and the unit is in decibels, dB. You could also measure it with a microphone and oscilloscope, provided you could calibrate them against standard instruments.

How do we measure pitch and volume?
We measure pitch with frequency and volume with amplitude.
How do you determine the ratio of an amplitude?
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.
What is amplitude ratio?
A measure of the strength of a wave is its amplitude which is the vertical distance between the heights of the wave's peaks and the heights of its troughs. An ocean wave might be said to be 20 metres high, for instance, meaning that an observer can see that the bottom of the wave is 20 metres below the top of the wave. The amplitude of that wave would be 20 metres. If you wanted to compare two waves you could use their amplitude ratio, simply the ratio of their two amplitudes.
What machine is used to measure sound waves?
what machine can be used to measure sound waves
What is the standard unit of amplitude?
As radio frequency, in would be modulation in hertz, kilohertz, megahertz. In other areas of measure it could be peak-to-peak. I.E. the maximum absolute value of some quantity that varies, usually with regular frequency. The unit of amplitude depends specifically on the type of wave, certain mechanical waves (e.g. those in in a plucked guitar string) have amplitudes measured in metres. Pressure waves (such as sound) have the unit of pressure as their amplitude (Pascals) where as electromagnetic waves use the electric field strength in volts/metre as the unit of amplitude. As you look at an oscilloscope, the vertical peak of a waveform From Wikipedia: The maximum absolute value of the vertical component of a curve or function, especially one that is periodic.
What is the amplitude of a sound wave a measure of?
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.
What does the the amplitude look like for a loud sound?
The amplitude of a sound wave is a measure of its loudness. A loud sound will have a higher amplitude.
What does amplitude measure?
Sound energy travels in waves and is measured in frequency and amplitude
What kind of wave in which amplitude changes to create sound?
The type of wave in which amplitude changes to create sound is a sound wave. Amplitude is the measure of the changes within the wave.
What instrument measures the amplitude of sound on a mobile?
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
What does wave amplitude measure?
Wave amplitude is the strong or weak of the wave, like in sound, it would be the volume.
What is measure of sound?
If you measure amplitude, then it's decibels (dB). If you measure frequency, then it's Hertz (Hz).
Measure the force of a compression and describes how loud a sound is?
Ithink the answer is amplitude
How could you use amplitude in a sentence?
There are many methods of measuring the amplitude of sound waves.Amplitude corresponds to the loudness of the sound.
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.
Intensity depends on amplitude and also on?
When talking about sound, the intensity of the sound is calculated the sound pressure multiplied by the velocity. It doesn't use amplitude in its calculation.
What is the difference between a loud and soft sound?
Sound is actually a vibration in the air which travels in the form of a wave. The larger the amplitude of the wave, the "louder" the sound. the smaller the amplitude of the wave, the "softer" the sound.
