I'm looking at the above materials : if they're stick to bedroom doors (where more than 95% of
the noises goes thru my daughter's room from my autist son's shoutings/wailings), will they
reduce more than 70% of the noise?
In particular I saw one in link below which has a specs of 200 MIL : what's this MIL & if the MIL
is higher, does it block sounds/noises more effectively?
Are those made in China ones as good in noise insulation? They did not give any specs though
In cases where people has drums & loud musical equipment, I've heard they insulate their
rooms with certain materials. Are these insulators from music industry as good as those
"sound deadeners" listed in eBay in blocking off sounds?
