17dB
17dB is a notation for a level expressed in decibels (dB), a logarithmic unit used in engineering disciplines to represent ratios. In audio and signal processing, a measurement of 17 dB indicates that the signal is roughly 11.2 times greater in power than a reference level. This figure is often encountered when evaluating audio equipment, speaker efficiency, or electronic components.
In loudspeaker and headphone manufacturers’ specifications, 17 dB may be cited as the gain of a built‑in
Decibels are calculated using the logarithm of a power ratio multiplied by 10, or an amplitude ratio
Because decibel values are dimensionless, 17 dB has no inherent meaning outside of its context. Engineers always
