Signal-to-Noise Ratio in Physical Education Settings

It is generally known that in educational settings, excessive noise masks what the teacher is saying; thus, and for maximum learning to occur, the teacher's voice must be highly intelligible to all children (Crandell, Smaldino, & Flexer, 1995). The difference between what the teacher is saying (signal) and the classroom noise level is commonly called the signal-to-noise ratio (SNR). SNR is a simple, useful comparison for estimating how understandable speech is in a room. The purpose of this study was to investigate the adequacy of the SNR in physical education settings. Investigating the adequacy of SNRs through comparison with recommended standards is a first step to establish an SNR baseline to further investigate its effect on student learning.
