Measurement of room sound pressure level difference (airborne sound insulation performance measurement)
We measure and evaluate how much sound is blocked by the building's partition walls and floors.
Generate pink noise in the sound source room, measure the sound pressure levels on the source side and the receiving side, and calculate the inter-room sound pressure level difference. From the results, calculate and evaluate the D value.
