Sound Field Amplification

The aim of this study was to examine the effects of sound-field amplification intervention on the acquisition of specific educational goals for children in mainstream cross-cultural classrooms. Twelve classes of Year 2 children participated in the project. For classes 1 to 8, the listening environments were alternated between amplified and unamplified conditions, each condition being for two terms (one semester) of the school year. Beneficial effects of amplification were obtained in all three skill areas of reading, writing and numeracy. The beneficial effects occurred irrespective of whether the children had English as a native language or as a second language. Classes 9 to 12 were alternated between single-channel and dual-channel transmission options, each condition being for one semester of the school year. The results indicated that using different numbers of microphones did not affect the rate of acquisition of educational outcomes.

Sound Field Amplification

This article presents teachers' and children's views of the effectiveness of sound-field amplification intervention. The rating scale, Teacher Opinions re Performance in Classrooms (TOPIC) provided information on teacher perceptions regarding changes in student performance in unamplified ‘OFF’ and amplified ‘ON’ listening conditions. The teachers observed improvement in attention, communication strategies and classroom behaviour when the amplification systems were operating. The answers from questionnaires indicated a high level of satisfaction from both teachers and students following use of the systems. Less vocal strain was identified by the teachers to be a major benefit. The children reported that they could hear better, clearer or louder.

Sound Field Amplification

Because teachers manage and instruct students through verbal communication, it would seem logical that improvement of pupil's abilities to detect and attend to the teacher's speech could improve pupil performance. Using sound field amplification which increased the intensity of the teacher's voice by 10 dB, nine children who attended a primary-level class for children with developmental disabilities, made significantly fewer errors on a word identification task than they made without amplification. Observation showed the children to be more relaxed and to respond more quickly in the amplified condition.

The Impact

PURPOSE: This review aimed at presenting the benefits regarding the speech perception in noise shown by children who wear hearing aid devices and/or cochlear implants with the Frequency Modulation (FM) System at school. RESEARCH STRATEGY: A bibliographic survey was conducted in an electronic database with standardized search until the year 2012, and a manual search was performed by using specific keywords. SELECTION CRITERIA: For the selection and evaluation of the scientific studies chosen in the search, criteria were established covering the following aspects: type of study, participants, adopted intervention, and evaluation of results. DATA ANALYSIS: The FM system was verified to improve speech perception and speech threshold in noise in all studies. RESULTS: Regarding the performance as to type, the best results were obtained when children used the personal FM system, followed by the table and the sound field systems. CONCLUSION: After extensive review of national and international literature, it was concluded that the studies indicate the need for further research concerning mainly the impact of the FM system on the school performance of children who have sensory devices coupled to the FM system. Findings in the literature with relation to the publications focused on speech perception in noise did not relate educational and auditory aspects.
