Results Sevral tests were messured for every material inside the box to conclude the decible diference between the empty box and filled boxes. The final result was the towels with a 53.12 deciple difference. Conclusions/Discussion several tests were made to show that house hold material can sound proof and is a good alternative sorce for insolating.
