Sažetak
Several reports confirm that high levels of interior noise in small GA aircraft considerably downgrade the quality of speech communication, confirming this setback as a serious flight safety issue. In order to quantify the levels of interaction between cockpit speech and noise, numerous octave-band noise measurements in Cessna 172R cabin have been conducted during various flight conditions, from which Speech Interference Level (SIL) and Speech Intelligibility Index (SII) were derived. The subsequent comparison of the results was made and presented in this paper. Although based on different grounds, these two methods have shown acceptable degree of correlation under given conditions.
