Does Every Insulation Material Block Sound?
Noise is one of the biggest complaints for everyone. Sounds from vehicles, construction or work areas, noises in apartments and similar crowded living spaces, and loud noises from construction or factory machinery cause noise pollution that we encounter in many places. However, even though the sources of noise are numerous, there are methods that can be used to prevent noise. You can insulate your environment from noise even if you cannot move away from noisy areas.
There are many materials used for insulation. Glass wool, rock wool, acoustic sponge coatings, polyurethane foam materials, or polystyrene materials can be among them. However, not all of these materials, which are selected according to their purpose of use, have sound-blocking properties. To prevent or minimize sound transmission, materials with open pores must be used. Rock wool, glass wool, and acoustic sponge materials prepared for this purpose are ideal materials for preventing sound transmission. Due to their open-pored structure, sound that hits these materials is trapped inside. This is the biggest factor in reducing sound. However, materials containing polystyrene have closed pores and therefore do not prevent sound transmission.
Most Effective Solutions for Sound Prevention
Foams or sheets containing polystyrene are generally used for thermal insulation because there is no place to trap sound inside. One of the reasons for excessive noise in some buildings is that only thermal insulation work is done. This causes sound to spread easily.
Preventing sound transmission is actually related to the problem itself. If you want a house to be soundproof, you can prevent sound transmission by covering its walls or floor with acoustic sponge sheets. However, if the problem is to prevent any vehicle in use from transmitting sound, then coating fabrics are more commonly used. Acoustic fabric coatings are preferred more due to their ease of application and ability to conform to the shape of the sound-emitting vehicle. The prices of materials used for sound prevention will vary more depending on the properties of the product and the area to be covered.
