≠ density

Sound insulation = sound absorption (energy absorption) + sound insulation (high density) to block sound penetration

densedegrees = weight

NE-100 sound insulation cotton density = 120 kg/m3 (weight per cubic meter = 120 kg)

NE-200 sound insulation blanket density = 1200

kg/m3 (weight per cubic meter = 1200 kg)

Highest density sponge = 50kg/m3 ONLY

 (weight per cubic meter = 50 kg) ONLY
