The sound insulation effect is too bad. What do you mean by smart home?

Recently, the cooperation between Apple and R&F Properties has led to extensive discussions in the field of smart homes . For a time, the smart home assembly market (that is, the overall home solution that runs through all aspects of design, material selection and construction) is no different.

The sound insulation effect is too bad. What do you mean by smart home?

However, as a place where we have lived for a long time, is smart home as long as it is hardware-smart and easy to operate? Especially in the era of real estate, the gap between real estate is getting smaller and smaller, and residential buildings are getting closer and closer to the streets. The problem of noise interference in civil buildings is becoming more and more prominent, and the call for reducing noise and improving the acoustic environment is increasingly strong. As a smart home that represents the scene of future life, if you can't meet the sound insulation design of the building, you can't be a qualified residential building.

So, what is a qualified building sound insulation design? What issues need to be paid attention to during construction? Below, we interpret GB50118-2010 "Code for Design of Sound insulation for civil buildings".

Comparison of sound insulation of residential partition wall structure

The background noise in the building interior is mainly due to external incoming noise, and the lack of sound insulation of the building envelope structure is the main reason that affects the noise level of the noise sensitive room. During the construction process, the sound insulation of the hollow brick wall, the concrete hollow block wall and the aerated concrete block wall is lower than the solid brick wall of the same thickness, the sound insulation and the thickness of the wall, the pores between the blocks, the mortar of plastering Quality related.

Sound insulation of lightweight composite partition wall used in building envelope structure: single light steel keel gypsum board <intermediate added mineral wool board <double light steel keel gypsum board <added sound insulation felt <double light steel keel damping partition Sound board. Double light steel keel + gypsum board + double damping sound insulation board + double mineral wool board can achieve sound insulation up to 60dB (A), which can meet the requirements of high sound insulation.
