if you know the specific gravity of a substance, how can you determine its pcf density (assuming you know the pcf density of the reference substance, usually water)

Aug 24, 2017 ... My understanding is that thick bass traps perform better when lower density insulation is used, but how low in density does this actually mean? 1.0# Density 1.25# Density 1.5# Density 2.0# Density.
