Noise has become one of the public hazards that pollute the human social environment, and it has become the three major sources of pollution alongside air pollution and water pollution. Scientific research has shown that noise not only affects and damages people’s hearing, but also affects the cardiovascular system, The nervous system and endocrine system are affected. Noise has a huge impact on people’s psychology and physiology. Therefore, in the room decoration, we must not ignore the prevention and treatment of indoor noise pollution.
As far as the average person is concerned, the human body’s ability to withstand noise is about 50 decibels. The increase in noise sound pressure will cause the harm to the human body to be correspondingly clamped. The lighter one can make people feel irritable, affect people’s working mood and reduce labor efficiency; the severer cause serious damage to hearing fatigue. Household noise is generally low-frequency noise. The low-frequency noise does not sound very large and does not feel obvious. If it is detected, most of it will not exceed the standard. When the continuous indoor noise exceeds 30 decibels, Kenneng will have symptoms such as inattention. Find out the cause of the household noise, and prescribe the right medicine to fundamentally manage household noise.
Five reasons for indoor noise:
1. It is the outdoor noise transmitted through doors and windows. Noise can be reduced by following soundproof windows and doors.
2. It is the voice of neighbors’ life that comes in through the transfer wall. It can be controlled by installing sound insulation boards, sound-absorbing cotton and other sound insulation materials.
3. It is the sound transmitted through indoor heating and upper and lower drainage pipes. The noise can be reduced through effective noise reduction processing on the pipeline.
4. The sound is transmitted through the floor of the building. It can be controlled by materials such as sound insulation felt.
5. Sound is transmitted through the pump room, elevator and other equipment in the building. At this time, the pump room and elevator should be treated with sound absorption and noise reduction.
How to reduce indoor noise pollution at ordinary times:
It is very important to choose the materials and craftsmanship in the decoration stage. For example, the use of solid wood flooring on the ground has better sound insulation; carpets on the ground or passages can also reduce noise; professional sound insulation materials can be used as sound insulation ceilings; 90% of external noise comes from doors and windows, so choose sound insulation Doors and soundproof windows are very important; cloth craft decoration and soft decoration are often used. Generally speaking, the thicker the curtain, the better the sound absorption effect, and the best texture is cotton and linen; placing some green plants with more branches and leaves on the window sills and balconies facing the street can also reduce the introduction of noise.
