If money is running low and you need to soundproof a room for band practice, a recording session or just to play your favourite artist at a volume that's likely to annoy the neighbours, some people say that egg cartons will go a long way in dampening the decibels. Although nowhere near as effective as professional soundproofing, egg cartons may, at the very least, reduce the number of complaints you receive.
Collect as many egg cartons as you can find. It's a good idea to measure the space you want to soundproof and keep a track of the square footage of the cartons you collect. Ask friends and family to save their used egg cartons and approach local stores or farms that sell loose eggs to see if you might be able to commandeer their castoffs.
It's not necessary to increase your intake of eggs, as you'll be surprised how quickly you'll accumulate what you need. Remember you'll need to account for the ceiling of the room you want to soundproof. It's a good idea to make sure you have an excess of what you'll need to cover the whole area in case of errors.
Glue your egg cartons together to make larger tiles. Make sure these aren't too big for you to handle as you'll need to get these onto your walls and ceilings. Apply a generous amount of adhesive to the outside edge of each carton and stick together leaving no gap. If you have collected enough egg cartons, it's a good idea to double the thickness of your soundproofing by sticking cartons together to make two layers.
Nail or pin your egg cartons to the wall and ceiling. Glue the egg carton tiles you've made together to seal as you go to make sure there are no gaps through which sound can escape. Make sure you cover any doors or windows in the room.
Nail or pin the blankets over the egg cartons to increase the absorption of sound. Block any gaps around doors or windows with material.
Turn your music up and note how many fewer complaints, if any, you receive.
