According to the American Speech-Language-Hearing Association (ASHA) – teachers are generally unaware of the efffects that poor classroom acoustics have on learning.
Most teachers are unaware that the typical classroom may not be providing the best environment for listening and learning due to poor acoustic characteristics. Important information may be lost because a deteriorated or weak speech signal reaches the learner which makes listening difficult and creates significant gaps in learning.
Their research indicates that most teachers neither attempt acoustic improvements in their classrooms, nor welcome an amplification system or acoustic modifications.
They also argue for speech-language pathologists to consider educating teachers on the effects of poor acoustics on student learning, at-risk students, teacher vocal health, and the means for obtaining grants for amplification systems until designs for acoustical accommodations can be provided for classroom.
