Hello everyone,

         I am modeling this enclosure to isolate vibrations and acoustic noise in the frequency range of 30-70 Hz. Does anyone know of any damping material (for structural damping) or any barrier material (airborne noise) that could work in this frequency range? The enclosure is made of mild steel and measures 35in*21*20in and weighs about 106 lbs. Thank you.
