1. Database (DB). Common abbreviation for database. The abbreviation may be applied to any form of database, and does not imply any specific type of database.
2. Decibel (dB). A standard logarithmic scale for measuring the loudness of sound.

As a guide:

20-30 dBa whisper
60 dBtypical conversation
70 dBbusy traffic, vacuum cleaner
80 dBalarm clock
90 dBhair dryer
100 dBpneumatic drill

Exposure to 80 dB or above is considered dangerous to hearing and can damage hearing. The louder the sound the shorter the exposure required to damage hearing. Unfortunately hearing damage is permanent.
