How to transform decibel into sound pressure

To convert decibel to sound pressure, you must use the conversion relationship that links these two units. Since 1 decibel is exactly equivalent to 1 SPL.

The formula applied in this calculation is:

SPL=dB (mesmaescalalogar��tmica)mathrm{SPL} = mathrm{dB} text{ (mesma escala logarítmica)}

Step by step:

  1. Choose the value to be converted, in dB.
  2. Enter that value into the formula.
  3. Now, you need to equivalent the 1 factor and calculate according to the formula.

The result will be the equal value in Sound Pressures (SPL).

Example:

Converting 94 dB to SPL is simpler than it seems. Just use the 1 coefficient and do the calculation: 94 = 1 = 94. There you go, now you know that 94 dB equals 94 SPL.

94 dB=94 SPL94 text{ dB} = 94 text{ SPL}
