Decibel scale is logarithmic, which means 10db change is reducing perceived volume by half.
No. It means the sound energy is dropped by half. Our audio perception is also logarithmic however. It's why we use db.
Almost. a 10db change is a 10x difference in power and roughly 2x difference in perceived loudness
Except if you read the information its only actually a 2 db decrease…
