I had a question about this. Very aggravating.

I just found this on and I think it will help.

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. ... rdinances/
