Panasonic WX-LT350 Classroom Sound Field Amplification - Page 2

...cont'd from 3rd to 6th grade in four elementary schools. The data suggests a cumulative effect of minimal hearing loss on academic achievement and that many of these students would qualify for services that LD students receive. Two instructional techniques were applied in the study: teacher voice amplification and small group instruction. In each of the four schools, one classroom in each grade was equipped with equipment to amplify the teacher's voice. The teacher wore a lightweight wireless microphone that projected a consistent signal approximately 10 dB above classroom noise levels. The remaining students were in non-amplified classrooms and received supplemental instruction individually or in small groups. All grade levels that received sound field amplification significantly increased SRA academic achievement test standard scores. This change was equal to or greater than the scores obtained from resource room instruction. The following reasons prove sound field amplification to be more cost effective: 1. Staff utilization (requiring fewer personnel to achieve academic gains). 2. Lower initial and continuing instructional costs. 3. More legally defensible when considered within the context of the least restrictive environment mandates. [email protected] 877.268.7215
