Often people want to filter out unwanted noise so that the sounds they do want are more clear and precise without ‘white’ or background noise. Acoustical engineering is the science that focuses on that very process. In rooms such as recording studios or home theatres, acoustical foam can be installed to absorb unwanted sounds from the outside and provide complete soundproofing. We need to soundproof the walls between some rooms and also in a new bedroom we will be adding. What is the best way to block sound and will the same methods work for the old walls and a new efficient bedroom.

Common Methods Of Sound Proofing:

In most homes and commercial buildings, walls and floors have an interior support structure of wood or steel studs or joists and are covered with some form of rigid sheeting like drywall or particle board flooring, leaving an air space between the walls, floors and ceilings. That air space allows for the easy transfer of sound waves with very little solid mass for the sound to vibrate through or slow its transfer. One of the most common methods used to reduce the transfer of that sound has been to insulate the wall, floor or ceiling with one of several types of insulation. This may reduce the transfer of sound vibrations through the air space, but does nothing to stop the sound transferred through studs, drywall, joists or flooring. It’s also important to understand that not all sound frequencies are the same when it comes to insulation. Lab tests show that low frequency sounds aren’t stopped by insulation, and high frequency sounds aren’t reduced significantly. Insulating the air space is only effective in deadening mid-range frequency sound. For more info see

Another thing to remember when buying sound proofing materials on the internet is that you’re dealing with a company that could be anywhere. Make certain that their web site shows you who they are, where they are, and how to contact them via other means than email. You should be able to call and speak to someone if you have questions. Sound proofing Stuff isn’t cheap. Don’t be afraid to get help. These are the many different means that you can use to soundproof your environment. The prices can vary depending on how much sound you wish to block and how big of an area you wish to cover. With careful research, you should be well on your way to a more peaceful and quiet environment.
