DEWETRON introduced a sound level option for its measurement software OXYGEN which is available starting from version 5.2 of the software.

This option automatically calculates the time dependent frequency weighted and time weighted sound pressure level, the energy equivalent sound pressure level and many other parameters.

This whitepaper describes the mathematical calculations behind the values that are automatically provided by the OXYGEN sound level option and gives some application examples of when to use them. You can download it here.
