Speech intelligibility index calculations in light aircraft cabin during flight

High levels of cabin noise in small general aviation aircraft significantly deteriorate the quality of speech communications and potentially endanger the safety of flight. Several ground and inflight cabin noise measurements on new generation Cessna 172R were made during various phases of flight. The results are analyzed and used for Speech Intelligibility Index (SII) calculations, in order to quantify the influence of cabin noise on speech communications between crew members.
