VA-Lab ARCH

Product Features

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.
