What is dB, dB level, Leq and SPL?

If you don’t know what these words are, it is time to clear them up.

The sound pressure level is the ratio of the absolute sound pressure against a reference level of sound in the air.

Decibels (dB) is the unit of sound measurement. In other words loudness of sound or SPL is measured in decibels (dB). When the dB level is high, loudness is correspondingly high. You can learn more about dB from Wikipedia.

decibel level(dB levels) can be measured by using a sound meter/decibel reader device(Or app from now :D)

Look at the decibel scale below here. You can use this image when you use the sound meter app.
