Noise is one of the most disturbing environmental problems in today’s societies, becoming more serious with increased traffic and rapid industrial expansion. One solution to this problem is to use acoustic sound-absorbing foam panels. Over the past decade, flexible polyurethane foam has been recognized as an efficient material in the acoustic absorption industry due to its effective damping power, low density, high moldability, and easy production. The most important feature of flexible polyurethane foams is the presence of open-cell pores, which not only control the mechanical properties of the foam but also its sound-insulating properties. This study aims to investigate the applications, development, chemical and physical structure, and factors affecting the properties of foams due to sound absorption and mechanical energy loss of sound waves.
How Does an Acoustic Sound-Absorbing Foam Panel Work?
Sound waves can be reflected from hard walls, creating unpleasant echoes. Acoustic foam works by absorbing these sound waves, which, due to the special open-pore material structure of the acoustic foam, slows down or suppresses the incoming air particle vibrations, i.e., sound. As a result, noise or only specific frequency ranges are absorbed. This is especially useful for sound absorption measures to improve room acoustics, such as halls or concert venues. When sound is absorbed through porous materials, the sound energy is converted into thermal energy, which, however, remains negligible. This conversion occurs through friction as the excited air particles penetrate and move through the pores of the acoustic foam. The more open and deeper the pores of the acoustic foam, the more effective this friction process is, and the sound is absorbed. Sound-insulating elements made from acoustic foam can significantly reduce the noise level of a room and suppress noise.
Pyramid Panels
Acoustic pyramid foam panels work by absorbing sound waves. The pyramid shape of the product is designed to maximize the sound absorption surface, making it cost-effective and efficient for soundproofing rooms or studios. Studio sound insulation foam is the best choice for open spaces.
Flexi Panels
Flexi panels, usually used in high-demand rooms like recording or broadcast studios, offer one of the best acoustic solutions available on the market at an attractive price. They also have a unique feature: when placed in a sequence, the panel joints become imperceptible, allowing you to hide cables in the cavities.
Affordable Acoustic Panels
Affordable pyramid acoustic panels are special panels that help prevent and absorb sound frequencies. Each panel measures 500×500 with a thickness of 5 cm, ideal for reducing sound waves in your audio environment. This product is great for studios, recording rooms, home theaters, and any other audio environment that can benefit from acoustic treatment.
