Product Details

The compact size and broad frequency range make this source attractive for airborne power insertion in spaces or enclosed volumes for Statistical Energy Analysis (SEA).  Measurement rooms and even small noise emission test-beds can be calibrated using Qmir.  Test set-ups include verification of product/machinery test rigs and smaller anechoic cabins or reverberation chambers.  Qmir is also highly suitable for in-situ sound power evaluation in difficult or narrow spaces.
