DIY tips to soundproof a TV wall

However, this does not rule out other possibilities. There are a few different options for soundproofing the wall behind the television. While not as effective as expert sound-insulating and acoustic devices, they are better than nothing and may be useful.

Reorganise your furniture

The first thing you may do is rearrange the furnishings you already have. Large and heavy furniture, such as bookcases or chests of drawers, should be moved as close as possible to the wall you want to soundproof. Some of the unpleasant sounds will be blocked by the dense bulk. If you want to soundproof your television, you can position or mount it on one of these furniture items.

Use Soft furnishings

Soft furnishings are similar to acoustic foam panels in that they absorb sound. They’re soft and porous, so they don’t prevent sound, but they can soak it rather well. This could aid in the bafflement of unpleasant noises as well as higher frequencies. So collect as much soft furniture as you can i.e. carpets, rugs, pillows, cushions, heavy curtains, tapestries, upholstered chairs and arrange them around the television, on the wall behind the television, and around the room. You can also use them to remodel and spruce up your home’s interior.
