What materials are most soundproof?
If you want a quieter environment, the most important thing is to pick the right soundproofing material. Simply put, materials with good sound insulation are mainly those that can effectively block sound propagation, and usually these materials have high density and porosity. Specifically, like polyester fiber sound absorbing board, sound insulation cotton, foam board, glass wool, etc., all have very good sound insulation effect. If you need to renovate or remodel a room, these materials are the most commonly used option.
Polyester acoustic panels are currently one of the very popular sound insulation materials. Its main advantage is that it has good sound absorption, especially for high frequency sounds. Moderately dense, this material is effective at absorbing sound without blocking air circulation, making it suitable for a variety of scenarios, such as offices, homes, and entertainment venues. I have done sound insulation treatment at home, so I used polyester fiber sound-absorbing panels, which are also more convenient to install and stick directly on the wall, the effect is really obvious. The background sound and outside noise have been reduced a lot, especially since there was some traffic noise in my room, which now sounds much quieter.
In terms of price, the cost of polyester fiber sound-absorbing panels is about US$4 to US$7 per square meter.
2. Soundproof cotton
Sound insulation cotton is a very traditional sound insulation material, usually made of high density fiber materials such as mineral wool, glass wool or rock wool. It has particularly good sound insulation, especially for low-frequency noise (such as TV sound, deep music), which has a strong absorption capacity. For example, when decorating your home, if you want to isolate the sound from going upstairs and downstairs, using soundproof cotton will be very effective. I remember changing a bedroom curtain before, made of soundproof cotton, which worked more than expected, and the ambient noise was almost cut off.
However, the installation of soundproof cotton is relatively troublesome, because it generally requires the use of professional tools, or it needs to be filled into the gaps in the wall or roof. In terms of price, the price of soundproof cotton is about US$7 to US$12 per square meter. One disadvantage of this material is that it is easy to absorb moisture, so if used in a humid environment, it may affect the effect.
3. Glass wool
Glass wool is also a very common sound insulation material, especially suitable for use in buildings that need sound insulation, such as high-rise buildings or industrial plants. The main advantage of glass wool is that it is very light, but it has a strong ability to absorb sound. In particular, it can maintain good air circulation while isolating sound, which is very suitable for sound insulation treatment of walls or ceilings.
Glass wool is slightly more expensive, usually between US$10 and US$20 per square meter, the specific price depends on the brand and the quality of the material.
4. Foam Sheet (Polyurethane Foam Sheet)
Foam boards, especially polyurethane foam boards, are also the soundproofing material of choice for many due to their lighter characteristics and excellent soundproofing. It absorbs sound waves mainly through its porous structure, especially being very noticeable for high-frequency sound effects. In my home, I added a layer of polyurethane foam board to the curtains for auxiliary sound insulation, and the overall effect was quite ideal. This material has the advantage of being moisture and fireproof, suitable for all kinds of environments. The price ranges from about $6 to $13 per square meter.
5. Heavy curtains and soundproof windows
If you don’t want to go to war, start by improving the soundproofing of your windows. Choose a heavy soundproof curtain or install a soundproof window, which can greatly reduce external noise. This method is especially suitable for noisy, street-facing households in cities. I remember where I used to live, close to the road, and I was often woken up by the sound of traffic at night, and then I installed soundproof windows, and the effect was so immediate that I could hardly hear anything outside. Soundproof windows are slightly more expensive, usually between $50 and $120 per square meter, but are very effective for noise control.
6. Wall treatment with ground paving
In addition to the mere use of soundproofing materials, the overall wall treatment and floor paving can also be considered when decorating. For example, the wall surface can be enhanced with sound insulation by adding gypsum board or double-layer sound insulation board, while the ground surface can reduce the propagation of noise by laying heavy carpet or wooden flooring combined with sound insulation mats. My friend has recently made such a makeover, the noise in the living room and bedroom is almost cut off and the environment is quieter.
Summarize
Different soundproofing materials for different scenarios and needs. Polyester sound-absorbing panels, sound-insulating cotton and glass wool are suitable for use in walls and ceilings and can effectively absorb indoor and outdoor noise; foam panels and heavy curtains are suitable for rapid modification or reduction of specific types of noise. Depending on the source of noise in your environment, choosing the right soundproofing materials can effectively improve the comfort of living and working.
