Sound Converter

All calculations are based on the reference values on the first two fields.

The threshold of hearing is generally reported as the RMS sound pressure of 20 micro Pascals, i.e. 2×10-5 Pa, corresponding to a sound intensity of 0.98 pW/m² at 1 atmosphere and 25 °C. It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz. The corresponding value for the sound intensity is 1×10-12 W/m².

How to Use:
Type the value to convert into the field, behind which you find the unit. Click on any empty space in the window or on the “calculate” button. The converted result will be shown in the other fields. You can use the “reset” button to reset the process.
