...cont'd classroom acoustics, close SLD should be utilized whenever possible. One way to improve SLD is to use small group instruction over traditional seating arrangements. 3. Utilization of classroom amplification The implementation of classroom amplification can decrease SLD and significantly affect speech perception. The Mainstream Amplification Resource Room Study (MARRS, 1981) demonstrated drastic improvements in academic achievement when students received amplified instruction. By increasing the teacher's voice by approximately 10 dB and providing a uniform sound field throughout the classroom, students display perceptual and psycho-educational improvements. The large body of acoustic research in classrooms supports the need for good acoustics in teaching environments. Several strategies can alleviate the damaging effects of poor acoustics, one of which includes sound field amplification. By adopting these solutions and strategies, it will be in the best interest of the students. [email protected] 877.268.7215
