One I found a cool chamber at the top, near the entrance door to the room. Found again by the sound. All the plaster down I did not. Only a hole to get to the cavity with foam. Later, I decided to check out and the seam between PLATE, which converge in the end of the room corner.

The following are my steps – to put three-compartment plastic box and lay floor cover. I think this should be achieved to enhance the effect of sound insulation. There are certainly more and recommendation (read: in the aforementioned article on the construction site of "Master of OK!"). For example, it can be mounted ceiling, do soundproofing on the wall.

This is by far the most effective way to get rid of excess noise, including low frequency. It's very simple and can be even easier and more fun than all of the above actions. So what is this magic method? – Asks the impatient reader. To which I answer – to change a flat in pre-fabricated house to an apartment in a brick or monolithic, in a quiet and landscaped area with cultural neighbors, the beautiful city of culture … Incidentally, the real estate can be found here – on the construction site "Master OK"
