The decibel A filter is widely used. dBA roughly corresponds to the inverse of the
40 dB curve at 1 kHz equal-loudness curve for the human hearing.
An A curve always provides for "nice" values when low frequency noise signals are included. An A filter of a measured motorcycle noise must show untrue values. You should know that. From a dBA measurement no accurate description of the expected volume is possible.

What determines the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
How can you measure sound without a decibel meter?
The decibel meter is better known as a sound level meter. You can measure sound by a microphone and a vu meter, a peak meter, or a AC voltage meter. The reading given by such a meter does not correlate well to human-perceived loudness.
How i can measure sound frequency from sound level meter?
You just need a meter that measure Hertz (high and low) as well as db (volume)
What is most often used to measure the intensity of a sound?
The intensity of sound is most often measured by the Decibel meter. It can also be called the sound level meter or the dB Meter. It is used to accurately and objectively measure the sound or noise that one can hear.
What instrument measures sound intensity?
An oscilloscope measures electrical signal amplitude and wavelength. A decibel or sound-level meter. A cheap one is available at your local Walmart for about $20 located in the car audio section. If not instore, online. They make much better ones, but if you are looking to just get a rough idea, this is the way to go.
What are sound levels?
Usually sound pressure level (SPL) in decibels (dB) is meant. A sound level meter is an instrument which measures the sound pressure level. The reading from a sound pressure level meter (SPL meter) does not correlate well to human-perceived loudness.
What is the unit for the for the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
What determines the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
What is the gadget to measure sound volume?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
How do you make something to measure sound?
A microphone and a meter. A sound pressure level meter.
What is the name of noise level tester?
That is a sound pressure level meter (SPL meter).
where can i get a sound-level meter?
Electronics stores such as radioshack or best buy should have a sound-level meter. Apple also has a sound-level meter although I think it's just for Apple products. You can also try amazon.com
How are decibel measure?
Sound is measured in decibels by a sound pressure level meter (SPL-meter).
What equipment is used to measured sound?
sound level meter
What is the decible means?
A decibel meter is a device used to measure sound. Specifically, it measures sound pressure level, and is also known as a sound level meter.
How do you use a sound meter?
Scroll down to related links and look at "Sound level meter - Wikipedia".
What do you use to measure decibels?
You measure the sound pressure with a sound pressure level meter (SPL meter).
