Earth Bern vs Acoustic Wall
Posted: Sun Apr 21, 2019 2:41 pm
When picking whether an earth bern or acoustic wall for blocking highway noise, what is the criteria? which performs better?

Studies have shown that an earth berm is about 2 dBA less effective at reducing noise than a sound wall erected at the same height. The foot print of the earth berm can become very large in width to support the berm itself. If space is limited and the client wishes to install the sound barrier close to the noisy source, we recommend installing a barrier wall instead of an earth berm.
