One of the most common complaints from apartment residents is noise in their bedroom. Nothing is more frustrating than waking up in the middle of your sleep from footsteps, TV or household electronics.
A quick way to fix this problem is tweaking your bedroom door. A conventional, mass-produced apartment buildings are built with hollow-core doors. this means that your door is pieced together using two panels, with a honeycomb-like structure in between. this type of doors does VERY LITTLE in blocking out sounds. The quickest way is to install a solid wood door.
Solid Wood Door & Door Sweep
A typical solid wood door has a sound transmission class index of 25, including the spaces around the door. The sound-proofing effect can be greatly increased by installing an acoustic sound sweep that you can find any major hardware stores. The idea is to cover up all the space that sound waves can travel through.
Acoustic Sound Kit
Now if installing the door sweep does not do the trick, try purchasing an acoustic door kit which is a set of metal bars that you can drill into on the four sides of the door frame. This does affect the aesthetic of your home unfortunately.
There are curious inventions to eliminate sounds. You can purchase a sound barrier for your residential home that mimics that effect of a professional recording studio. These barriers can be hung like a curtain or installed directly onto your door. The better ones allow you to roll up to the door frame.
