How much sound will an Oscar Iso-Mount soundproof ceiling eliminate?
Acoustic testing has shown that a significant failure of Building Regulations Approved Document E can be turned into an easy pass. Independent testing on a house (ref 19 Wilberforce Road) showed that resistance to airbourne sound (speech, music etc.) increased by 23dB DnT, + Ctr and impact sound insulation increased by 24dB LnT,w; a significant and worthwhile difference.
The installation of the Oscar Iso-Mount Type1 soundproof ceiling system achieved (better than) compliance with the stringent requirements of the 2010 Building Regulations Approved Document E for Airbourne and Impact Sound.
