Abstract

Sound absorbing board (10) is made from recycled high density foam granulate (12) that has been mixed with a binder (14) and consolidated under pressure. Pores (16) are present in spaces between the granules. Each granule includes small pores (18). Sound is absorbed by thermal diffusion and viscous friction.
