Make Your House Sound Proofing

Acoustic Treatment

Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active antinoise sound generators. Let us categories the noise into two types, outside noise and inside noise.

Outside noise

Not only will noise sneak through every crack and gap, it will reverberate through any lightweight building material. So, the first step is to figure out which rooms need sound insulation. To do this, turn off everything in the house and listen carefully – at different times of the day – to where external sound is emanating. Examine walls, doors, windows, ceilings and floors and listen carefully. Immediate improvements can be made by sealing up cracks and holes around windows and doors, using polyurethane or latex caulk. Also, pack putty or high density polyester absorber around pipes and wires where they enter the house. Then seal the area with acoustic and fire rated sealant.

Double-glazed windows will make a huge difference and can be fitted to your existing windows but ensure existing windows are fitted with acoustically rated seals. When designing or renovating your house, position sound-sensitive rooms, such as the bedrooms and the study, next to each other. Ensure that waste pipes and plumbing are situated away from these quiet zones or are soundproofed with acoustically rated pipe lagging material. Even if your walls and windows are completely soundproof, don’t forget about the roof. Check that there are no gaps in the roof tiles and add insulation if necessary. If the neighbors or traffic noise is sending you mad, add trees, hedges or fences around the property. This will help deaden the sound and provide psychological relief by blocking noise sources from view.

Inside noise


Ceiling insulation, consisting of polyester batts, is a key element when minimizing noise. “It can be installed in a way to improve the acoustics of any room, as well as being a heat and cold insulator. If you’re introducing a media room – or even a playroom where teenagers like to pump up the volume – look at specialized sound barriers, such as wall carpet, soundproof tiles or ceiling baffles.

Throughout the interior, builders and joiners offer purpose-made plasterboard that can aid in noise reduction. If you’re working from home or if the kids need quiet homework time, replace the study’s hollow-core door with a heavy solid-core one and fit acoustically rated door seals. This will minimize sound transmission and deaden the sound of the TV from the other room.  When it comes to flooring, hard surfaces such as tiles or timber will reflect any sound in the space. This can give a room an echoey quality. An easy solution is adding some curtains, rugs or carpet. Even a big comfy sofa or bed will break up sound waves. This will also help reduce the noise transmitted to other rooms. If you’re adding a second storey, install carpet with acoustically rated underlay in the upper room – it’s noise proof, comfy underfoot and adds warmth to the upstairs bedrooms.  On the ground floor, it’s worth building an acoustic suspended ceiling as it reduces noise and significantly improves the acoustics.

Noise can be killed if you followed the steps listed above.
