Similarly, the use of EAs as a sound deadening acoustical barrier
has been limited because of the relatively low density of these materials.
Part of this experience is due to the design - the post-tension concrete provides reduced building volume and is an excellent acoustical barrier
Gradient Density DbCore is a light-weight, recyclable acoustical barrier
with enhanced noise abatement characteristics capable of tuning out specifically targeted noises.
WindStop technology is an innovation that surrounds the microphone with an acoustical barrier
to filter the disruptive effects of wind noise, enabling clear conversations in adverse conditions.
in classrooms: the impact of noise on performance in the classroom.
Classroom Acoustics II: Acoustical Barriers
to Learning features information about the problems experienced by teachers and students as a result of noise and reverberation in the classroom and includes more than 150 additional references on the topic.
