VA-Lab ARCH module provides reverberation time measurements and sound transmission loss measurements according to ISO standards.
Main Features of VA-Lab ARCH
Two methods: interrupted noise, impulse response measure reverberation time in 1/1 or 1/3 octave frequencies according to ISO 3382
Sound pressure decay curves display, support user-defined reverberation time calculation
Airborne sound insulation of building elements Measurement
Measurements of impact sound insulation of floors
Automatically calculate single-number quantity: Rw, Xw, and its spectrum adaptation
VA-Lab ENV is a powerful sound level meter. It supports maximum 10 channel sound pressure level measurements at 10 locations. Each channel can perform multi-task analysis such as statistical levels, 1/3 octave, and levels vs. time. VA-Lab ENV has built-in data logger function, it can continuously log the overall and spectral data into the memory.
Main Features of VA-Lab ENV
