NEW YORK, Nov. 21, 2016 /PRNewswire/ -- The Quiet Room® label, the only global and objective label for quiet hotels rooms, is really taking off. More than 140 hotels in Europe have already acquired the label and the American market is showing great interest. But many hotels are still reluctant to make the necessary soundproofing investments. However, if architects and project developers ensure that the requirements of the QR label are met at the design and construction stage, great savings can be realized and hotel buildings will become more valuable.

With the help of this guide, construction professionals can gain an understanding of the QR label, the certification requirements and the latest methods for acoustic insulation of hotel rooms. By following the guidelines of this practical manual, they can make sure that new hotel buildings are fitted with the necessary soundproofing and acquire the Quiet Room® certification before they open their doors to the public. In this way a lot of time and money can be saved and hotels can achieve a stronger market position. In addition, the label's popularity and the huge interest of travelers in quiet hotel rooms will ensure a rapid return on investment. For the international consultancies which do acoustic calculations of the hotels we have a professional procedures manual.
