EVALUATOR

Evaluator Type 7820 is a software package for environmental noise evaluation. It provides versatile tools for analysing measured data from Brüel & Kjær Sound Level Meters, and is a complete solution for the determination of Rating Levels according to various national standards.

A Rating Level is a single value for evaluating the potential nuisance factor of noise. It takes into account time of day, nature of the noise (impulsive and pure tones present) as well as the overall level of noise. Evaluator boasts many advanced features, including recording and replaying sound, tonal assessment using FFT spectra and the option of remote downloading data from Brüel & Kjær Sound Level Meters through a modem connection.
