A decibel meter... the question is... do you really need to because i doubt you have a decibel meter
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".
Sound is measured in decibels by a sound pressure level meter (SPL-meter).
A decibel meter is used to measure sound. It is a handheld device and can be used to quickly measure how loud certain sounds are. They are sometimes used to measure how loud a crowd is in sports.
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.

Decibel levels are typically measured using a sound level meter. The meter captures sound pressure levels in decibels (dB). The measurement is usually taken at a specific location and distance from the noise source to determine the intensity of the sound.
Using a decibel meter: A decibel meter measures sound levels in decibels (dB). Using a sound level meter: A sound level meter provides a reading of sound pressure levels in decibels. Subjective rating: Loudness can also be evaluated subjectively based on human perception, ranging from "quiet" to "very loud".
