Question

How to convert 280.6 mPa to dBSPL?

The decibel is defined as ten times the logarithm of power gain, expressed as power out over power in. When we work with pressure, rather than power, we use the following modified version of the equation: dB = 20 log Prot Prin Sound pressure level (dBSPL) is defined by fixing the reference point (Prin) at 20 μPa (2x10-5Pa). Convert 280.6 mPa to dB SPL. (round your answer off to one decimal place)
