This is why concrete stairwells are akin to echo chambers, while a recording studio of the same size with foam-clad walls absorbs sound and reduces reverberations.
Sep 17, 2008 If you mounted the wind turbine on the roof directly, this is the real problem. You need to remove the wind turbine from the roof support and place the turbine on the ground next to, or isolated away from the building. Wind turbines in normal use should not exude more then ambient noise levels of 68 to 72 db.
