SPL to SWL

dB Foresight, SPL to SWL Conversion Form

dB Foresight requires the un-weighted SWL (sound power level) for point sources. If you know the SPL (sound pressure level), then you can use this form to compute the SWL. Enter the SPL at a given distance from the source and the directivity factor.

Note: If the form does not run the calculation, check that Java is enabled in your browser or try a different browser.
