Optimalization of the measurement system for determination of the diffusion and reflection coefficients
Original language description
This paper focuses on a new design of the measurement system for the characterization of reflective materials. The main aim of this work was effectively and reproducibly measure the diffusion and reflection coefficient. Presented measurement system allows to provide the multichannel synchronization record from 47 microphones in real-time. The measurement system consists of the microphone frame, connection cables and electronic devices (for amplifying, converting, processing of the signals etc.). The microphones are distributed uniformly in the frame with the shape of the semicircle with the radius of 5m. The fixed microphone frame ensures the producibility of each measurement. The frame is multifunctional: (1) mechanical protection, (2) electrical connection and (3) it ensures the first stage of amplifier and it also provides the power supply for the microphones. The frame can be also decomposed into smaller parts for easy transport. Becasuse of the very low value of the noise backgrou
