Everyone wants their home theatre to be luxurious and well equipped with best sound system, projector, screen, recliners  & carpet to enjoy multiplex like experience. But most of the people forget about the indispensable element of all which is soundproofing and acoustics. The two main goals of home theatre soundproofing is isolating the theatre’s sound from rest of the house or neighborhood and producing high quality premium sound inside the home theatre.

From where does the sound leak?

In a home theatre sound levels are ranging between 70db - 95dB, with a combination of low frequency sounds( Bass ) and high frequency sounds.  Controlling low frequency is the most important part of soundproofing a home theatre.  It passes through your thick walls, ceiling, floors, doors and windows.  For eg. If you play high volume of music in a car and stand outside with all windows closed, you might not hear the lyrics properly but the bass vibrations will be there.

How to control the sound in a home theatre?

Lets make it easy for you. To control low frequency sounds we need to add high density mass on the surface ( walls, floor, ceiling ) like SoundBlanket mass loaded vinyl or thicken you walls by brick or gypsum. To control high frequency sound waves we need to use a combination of  absorbers and diffusers.

High Density Mass – High density closed cell soundproofing membrane that blocks sound with STC 36

Sound Absorbers – Open cell high density acoustic foam for sound absorption with NRC 0.90

Sound Diffusers – Shaped surface to disperse sound in different direction.

Here is a step by step guide for soundproofing and acoustic treatment of a home theatre

Steps for Soundproofing + Acoustic treatment of a home theatre with MMT Acoustix® acoustic products :

Total Room Area = Area of wall + ceiling + floor

Step 2 –

Add mass to the walls for noise isolation using SoundBlanket mass loaded vinyl in 5mm thickness on walls & 3mm thickness on ceiling and floor.
