**The Speech Intelligibility Calculator
**

This page will calculate reverb time, critical distance, and expected %ALCONS for the room you input here. The results show the inter-relationship between reverberation time, room finishes, speaker selection and speech intelligibility.

**Wavelength of Sound Calculator
**

This calculator will tell you the wavelength of any airborne audio frequency in inches, feet and metres, based on the speed of sound at sea level, and at 20 degrees Celsius or 72 degrees Farenheit.

**dBu «» dBV «» Volt calculator
**

Calculate dBu, dBV and volt.
