I miss it, but it can be used as a soundproof decoration with simple boards. The wall is 7 centimeters and the top is 7 centimeters. It is best to specially make a shock-absorbing platform for the lower foot of the piano. Generally, people think that the lower foot pad is enough. After actual construction, it has been proved that the piano bracket has a large low-frequency transmission, and ordinary foot pads can only reduce 40% of low-frequency vibration. Windows should also be replaced with soundproof windows. Professional soundproofing. That is, if conditions permit, a room is dedicated as a practice room. Generally, professional sound insulation can be done if it is more than 11 square meters. The steps of the project are as follows: (1): Create a space of 1-2 centimeters outside the original wall. A new light steel keel wall, sandwich 5 cm of sound insulation cotton in the middle, add a layer of sound insulation felt on the keel surface, and seal the surface with gypsum board or other decorative materials. (2): The treatment of the windows is on the original In addition to the windows, a soundproof window is added. (3): To deal with the door, make a new thickened soundproof door, or add soundproofing measures to the original door. (4): Top suspended ceiling, original ceiling plus suspended soundproof ceiling. The general thickness is 13 cm. (5): For floor treatment, lay a 1.5--1.5 or above carpet on the floor, and add a shock-absorbing pad under the piano. 2: Ordinary sound insulation; hang some decorative carpets on the wall, or paste cork boards on the wall, lay a quilt behind the piano, and add shock-absorbing pads on the floor.
