That can't be done. Feet is an US amercan length unit and decibel loss is a ratio.
How do I convert a .db file?
yes
You cannot convert DBi to DB because they are not related. DBi is only for decibels in an isotropic radiator, while DB is only for decibels in a dipole antenna.
If I understand the question, it isn't possible to convert dB (a unit of sound energy) to litres (a unit of volume).
dB (decibel) is a logarithmic measure of the ratio of two power values, for example, two signal strengths. This is often used for power gain or power loss. For example, a loss of 10 dB means that the signal degrades by a factor of 10, a loss of 20 dB means that the signal degrades by a factor of 100, and a loss of 30 dB means that the signal degrades by a factor of 1000.
wb = db/(db+100)
It is impossible to convert dB to dBA. There is only a guess. Scroll down to related links and read "Correlation between sones und phons".
dB SPL is a comparison of a sound level to what was thought to be the threshold of hearing, although today it is known that the value was too high. dB HL is a measure of hearing loss - a comparison of a subjects hearing compared to a 'normal' standard. As they are measure different things a direct comparison is not possible. The differences between dB HL and dB SPL, arise from isophonic curves. There is no direct (linear) formula to convert this but a set of formulas. For different frequencies, different values should be added. For eg., at 1kHz you can state that 0dB HL is around 2dB SPL while at 250Hz, 0dB HL is 12 dB SPL. db HL = db Hearing Level db SPL = db Sound Pressure Level
using bode-m plots , one can tranfer dB magnitude to gain and gain to frequency
If there is a 3db loss that means 50 percent of the light were lost.
