- - Volt is often used as the quantity measured. In such cases, +6dB represents roughly a doubling in signal, 3dB a doubling in power and 10dB a doubling in perceived loudness.

+ - Volt is often used as the quantity measured. In such cases, **6dB** represents roughly a doubling in signal, **3dB** a doubling in power and **10dB** a doubling in perceived loudness (and negatives achieve halvings instead of doublings).
|
|
|
- Since a doubling in signal level results in a 6dB SPL change, a 16-bit digital sound representation gives 96dB of dynamic range.

- Specific dB-variants exist for measurements in specific use cases, e.g. dBu, dBFS, dB SPL etc.
