The purpose of this book is to provide a comprehensive and cohesive guide for the use of small, frequency modulated sound-field FM amplification systems in classrooms. The book addresses both theoretical and practical issues with an emphasis on application of information to real-world situations. Worksheets and checklists are included at the end of many chapters. The book's chapters are: (1) "Rationale for the Use of Sound-Field FM Amplification Systems in Classrooms"; (2) "Speech-Perception Processes in Children"; (3) "Speech Perception in the Classroom"; (4) "Speech Perception in Specific Populations"; (5) "Acoustic Measurements in Classrooms"; (6) "Acoustical Modifications within Schools"; (7) "Identifying and Managing the Learning Environment"; (8) "Sound-Field Amplification: A Review of the Literature"; (9) "Considerations and Strategies for Amplifying the Classroom"; (10) "Inservice Training for the Classroom Teacher"; (11) "Listening Strategies for Teachers and Students"; and (12) "Marketing Sound-Field Amplification Systems." Appendices contain related screening instruments and questionnaires, and a summary of studies on the use of sound-field amplification. (Each chapter contains references.) (EV)
