You measure the sound pressure with a sound pressure level meter (SPL meter).
That depends how close you measure to the mouth of the human speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. At 1 meter distance the speaker may be measured at 60 decibels SPL.
That depends how close you measure to the bat. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
Decibels
20 to 50 decibels (dB).
The sound pressure level of 80 dB is a 10 times higher measure than the sound pressure level of 60 dB. Louder ist not the correct word, because it belongs to psycho acoustics and tells the loudness feeling.
use a decibel meter
to measure sound from distance use decibels
Take a sound pressure level meter and measure it. 95 decibels means over the is 0 decibels is the threshold of hearing. 95 decibels means the measure over 0 decibels.
decibels
A drum kit is no decibels. The decibels depends how close you measure to the bat. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.

Decibels
Decibels are a logarithmic measure of a factor or a ratio and that has really nothing to do with metric or imperal.
decibels
Decibels/sound.
A decibel is a unit of measure of how loud is a sound. Just as inches are used to define length, pounds weight or degrees temperature, decibels define sound levels.
Decibels are the measure of how loud something is.
