How to deal with the strong noise from the hotel range hood outside the bedroom wall?

When the traditional range hood is just bought, the effect is better and the noise is not very big. However, after a period of use, due to the low efficiency of the traditional oil fume purification and filtration means of the range hood, the oil inside is getting thicker and thicker, which pollutes the inner wall of the range hood, resulting in a large amount of uneven oil accumulation on the impeller of the range hood, the dynamic balance of the fan is lost, the suction effect is naturally getting worse and worse, and the noise of the range hood is getting louder and louder. In addition, the "no disassembly and no washing" technology on the market is not mature, which makes most range hoods need to be disassembled and cleaned. After cleaning and reassembling the cover assembly several times, the installation position of the motor will shift and the fixing screws of the cover cavity will loosen. As soon as the range hood is turned on, the vibration of * * * will increase the noise decibel, resulting in the situation that the range hood is "big noise and small suction".

The state stipulates that the noise of range hoods should not exceed 68 decibels, but through investigation, the average noise of range hoods in the family is 70-78 decibels. The data show that the sound of 40-50 decibels is a relatively quiet normal environment for people; More than 60 decibels will affect sleep and rest; More than 70 decibels will cause harm to people, showing symptoms such as upset, dizziness, headache, neurasthenia and indigestion. Now there is a wall-mounted range hood, which completely solves the problem of loud noise of range hoods in the market at present. First, the noise of its main motor is 48 decibels, far below the national standard; Second, because the installation method is built in the wall (the main engine is in the wall), the secondary noise reduction is 2-3 decibels; Thirdly, centrifugal degreasing and oil filtering are adopted to realize real life-long disassembly and washing-free, so the vibration phenomenon caused by the range hood will not appear. Fourthly, the hood of the traditional range hood is very thin and small because it adopts the side suction technology and does not need a hood, so there will be no big noise and vibration of the shell. Tested by relevant state departments, the noise of the range hood is lower than 45 decibels, which is the lowest noise range hood on the market at present.

It is recommended that a friend find a professional noise control company to manage it, and the cost can be paid by the hotel.
