Inquiry (采购产品): need to reduce sound level Hello, We have recently installed a large concrete room with a stamping press. We have sound levels up to 100 db. I would like to know how to bring those levels down, how much the material cost would be, and who could install it, and for what installation price. Thank you, Kelly Coleman Sunnex Automotive Division 1-937-746-8575 ext. 1272 85 Pioneer Blvd Springboro Oh, 45066 or Sunstar Motorcycle Division 1-937-746-8575 ext. 1272 700 Watkins Glen Franklin, Ohio 45005 **** Hidden Message ***** kelly coleman 45004 AFG Company: sunnex Phone: 1-937-746-8575 E-mail: kcoleman@sunnexinc.com **** Hidden Message ***** kcoleman@sunnexinc.com
