用法筆記

Commonly used with a number: 'a 90‑decibel alarm' (hyphenated before a noun) or 'the alarm is 90 decibels loud.' The decibel scale is logarithmic, so a 10‑decibel increase corresponds to roughly twice the perceived loudness.

常見錯誤

The music has high decibels so it sounds high-pitched.
The music has a high frequency (measured in hertz); decibels measure how loud the sound is, not how high or low.
Decibels indicate loudness, not pitch.
Turn the volume up by two decibels to make it twice as loud.
An increase of about 10 decibels makes a sound seem roughly twice as loud.
