You can use more wooden furniture at home because it can effectively absorb sound. If the living environment is too noisy, you can put more wooden furniture at home. The sound absorption effect of wooden furniture is very good.
2. Door panel quality
The quality of the door panel also matters. Generally, the better the quality of door panels, the better the sound insulation effect. Moreover, if the door panel is well sealed after closing, it can be said that the sound insulation is also very good. Therefore, when installing the door panel, we must pay attention to the sealing performance. Generally, the higher the density of wood itself, the better the sound insulation effect.
3. Rough walls
The degree of sound insulation is also related to the roughness of the wall. Generally, the rougher the wall, the better the sound insulation effect. On the contrary, if the wall is smooth, it is easy to produce echoes indoors, which will increase the volume of noise, so wallpaper can be used to make the wall rough. In addition, for example, walls or ceilings can be decorated with materials with good sound insulation effect, and some gypsum boards can also have certain sound insulation effect.
4. Thick fabric
Thick fabrics can also reduce noise appropriately. Curtains absorb sound more easily than carpets. It is suggested that when laying carpets, try to lay some soft carpets. This soft carpet can also eliminate footsteps and help us have a rest.
Extended data:
Noise also has the following hazards:
1, affecting sleep quality. Studies have shown that noise of 40 ~ 50 decibels will interfere with sleep. 40 decibels of sudden noise can wake up 10% people, and 60 decibels can wake up 70% people. When the continuous noise reaches 70 decibels, it will affect 50% people's sleep.
2. Hearing organs are damaged. In the strong noise environment, people will feel harsh discomfort, pain, hearing loss, tinnitus, and even cause irreversible organic lesions, that is, noise deafness. Under the condition of noise of 85 decibels, if exposed to 15 years and 30 years, the incidence of noise-induced deafness is 5% and 8% respectively. Under the condition of 90 dB noise, the incidence of noise-induced deafness increased to 65,438+04% and 65,438+08% after long-term exposure for 65,438+05 and 30 years.
3, cause cardiovascular disease. A survey in Germany found that the risk of hypertension of residents with ambient noise above 55 decibels at night is twice as high as that of residents with ambient noise below 50 decibels.
When noise acts on the central nervous system, it will not only inhibit the function of cerebral cortex, cause headache, brain swelling, memory loss and other symptoms, but also make sympathetic nerves nervous, lead to accelerated heartbeat and arrhythmia, and cause cardiovascular diseases such as hypertension, heart disease and arteriosclerosis.
