The most commonly used conventional building materials, such as brick, concrete, stone, wood, and glass, have a number of advantageous properties. Perhaps the most important consideration is stability and durability, as properties are designed for long periods of time, years, decades, or even longer. For the prehistoric man, the caves provided protection against the weather and wildlife attacks. With the development of science, industry and civilization, buildings no longer have to meet only safety and security conditions. Different architectural styles often use different designs and building materials. When designing and building homes, workplaces and industrial facilities, architects also place great emphasis on thermal insulation, comfort and aesthetics.
Unfortunately, acoustic aspects are only very rarely taken into account in the construction of buildings. Probably the main reason for this is that most designers are unaware of the negative consequences of noise pollution. According to WHO surveys, the level of noise exposure is increasing year by year. Persistent noises reduce the ability to concentrate and remember, and can lead to headaches, depression, and hearing loss. In more severe cases, constant noise can cause digestive, nervous, cardiovascular problems and diseases. If our night’s sleep is disturbed by constant background noise, we can’t relax ourselves, we will be tired, exhausted, which will have a negative effect in the long run. Even in our workplace, we are usually surrounded by constant noise, which can result in a deterioration in our work performance.We can only ensure the peace of our homes and workplaces if we take care of the acoustic treatment of the properties. Traditional building materials, due to their structure, do not have sound absorption. In the past, noise reduction was not as important as people were exposed to much less noise. Of course, it was discovered as early as the 17th and 19th centuries that certain materials better attenuate noise, which is why, for example, large, heavy, densely woven velvet curtains were used in huge mansions. Nowadays, styrofoam is often used for heat and sound insulation, but since this material is not able to absorb sounds, it is a complete waste of time and money for such structured materials.
From an acoustic point of view, materials with a high density, a flexible, porous structure are suitable for noise attenuation, so that the absorbed sound can flow freely between the permeable pores. We can improve the acoustics of the rooms with layered, perforated materials. Sounds are reflected from excessively hard, flat surfaces and then bounce back and forth between the surfaces, causing echoes and interference. The sounds of our favourite music or movie only provide an experience if they sound clear, noiseless, without echo. It is not enough to buy expensive hi-fi equipment, it is definitely recommended to improve the surround sound of the rooms. Treating walls, ceilings, floors, and glass surfaces with acoustic materials can provide a solution to this problem.
Materials specially developed for acoustic purposes are also excellent for eliminating and attenuating external noise, such as unwanted sounds and noise from the street or neighbours. By using sound absorbers, diffuser panels and soundproof curtains, Soundproof Curtains and carpets, a significant improvement can be achieved in our homes and workplaces. A calm, harmonious atmosphere can be created, which has a positive effect on our physical and mental health as well. It would be most ideal if acoustic factors were taken into account when designing real estate, when choosing building materials and coverings. We can see how important noise attenuation is in our modern, noisy world and it is advisable to start at the basics.
