Does Mn/DOT have a program to provide insulation of private residences?
A. Adding sound insulation (windows and sound deadening materials or acoustical insulation) achieves interior noise attenuation only and does not address exterior receptor areas where Minnesota’s noise standards apply. The costs for acoustical insulation of typical single residences are considered disproportionate for the amount of attenuation achieved and the number of receptors affected. There may be cases involving schools, hospitals, nursing or convalescent homes, or other public buildings where the number of receptors and the noise sensitivity of the receptors may justify the expense of insulating for noise mitigation.
