Benefits of sound field amplification on speech perception and classroom behavior in the second language learning classroom.

Results of many studies of Sound Field Amplification (SFA) have shown a positive effect of SFA on both speech perception and classroom behavior in mainstream classrooms; however, to date, there have been few studies assessing SFA for second language learning (L2) classrooms. The present study assessed the impact of SFA on speech perception and classroom behavior in a grade four French immersion classroom. A single-subject small N repeated-measure design was used. Background noise was presented at 60 dBA, a level typically found in classrooms. The SFA system was preset to deliver a gain of 15 dB. Speech perception was measured with a dictation test of phonetically-balanced French words presented both in a list and embedded in sentences. Students were instructed to write down the words and sentences. Results are discussed in relation to the used of SFA as a cost effective educational tool to improve language perception and classroom behavior.
