Building drainage noise measuring system and method

Abstract

The invention discloses a building drainage noise measuring system and a method. The building drainage noise measuring system comprises a double-layer suite, a water supply and drainage system, noisemeasuring equipment and drainage pipes; the double-layer suite comprises an outer room and a room body arranged in the outer house, the outer room is arranged to be an upper layer and a lower layer, the room body is arranged in the outer room of the lower layer, and the structure of the room body is brick-concrete or reinforced concrete, wherein the room body comprises a to-be-measured chamber I provided with a water supply and drainage pipe; a stair structure which is connected with the upper and lower floors is arranged on one side of the to-be-measured chamber I which is provided with the water supply and drainage pipe, a sound insulation device is arranged between the stair mechanism and the to-be-measured chamber I, and a to-be-measured chamber II is arranged at the opposite side of the to-be-measured chamber I provided with the stair structure, and the other two sides of the to-be-measured chamber I are provided with a to-be-measured chamber III and a to-be-measured chamber IV, and the problem of arrangement of the building measurement system is solved, so that the building measurement system conforms to an actual building structure more accurately, so that the detected datais more accurate and more representative.

Description

technical field [0001] The invention relates to the field of building drainage and building acoustic detection, in particular to a measurement system and method for building drainage noise. Background technique [0002] Building drainage system noise is one of the most important sources of construction noise, which directly affects people's normal life and work. According to the provisions of the national standard GBJ118-88 "Code for Design of Sound Insulation of Civil Buildings", the noise in the bedroom at night shall not exceed 30dB, and the maximum shall not exceed 40dB. However, in actual tests, the noise generated by a considerable part of the drainage pipeline system is far greater than 40dB. In engineering examples, there is also no lack of disturbance of residents' sleep and annoying effects due to the noise generated by the drainage pipeline system, as well as neurasthenia and other non-specific diseases caused by it. [0003] Take a building drainage noise measu...
