There is a technical term for this kind of decibel-usage - dBFS (decibel full scale). The highest possible level of sound produced by audio equipment is 0 dBFS. All other levels are then expressed in negative numbers. Absolute silence in dBFS is -∞ (minus infinity), but in practical terms …
The decibel (symbol: dB) is a relative unit of measurement corresponding to one tenth of a bel (B).It is used to express the ratio of one value of a power or root-power quantity to another, on a logarithmic scale.A logarithmic quantity in decibels is called a level.Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.258 93) or (sometimes equivalently

The louder the noise, the higher the decibels. Human reaction: bearable for a short period of time; maximum vocal effort to be heard. Is it possible that my ears can get used to the noise that causes hearing loss? No. Decibel levels up to the earplug's NRR rating will be blocked out entirely. Stimuli are different pure tones at varied frequencies (units of Hertz [Hz] - or kilohertz [kHz]) and at different loudness intensities (units of decibels [dB] - a Jun 13, 2011 For instance: The average human voice registers at 25 to 35 decibels.
Any sound at or above 85 dBA is more likely to damage your hearing over time.
