Image via WikipediaPerformance in school is very dependent on hearing. Students with Auditory Processing Disorder often don't hear everything in class and, as a result, have lower grades or behavior problems.
Four factors can impact how well a student with Auditory Processing Disorder (APD) can hear the teacher:
- The Teacher's Voice
- The Teachers voice needs to be 15 to 20 decibels louder than the background noise. Many times a teacher's voice is only at the level of ambient noise.
- Ambient Noise in the Room
- Reverberation in the Classroom
- Classrooms are highly reverberant because of the hard and reflective surfaces of the walls, floors, and ceilings
- The Distance between the Teacher and the Students
- In a standard classroom, the best accoustics are in the yellow field in the diagram to the right. In a Soundfields, (a type of speaker system) enhanced classroom, accoustics are good throughout the room..
- Distance between a teacher and the student greatly impacts the student's ability to hear
