Two guiding principles decide whether a noise and vibration dampening solution works well. First of all, the architecture of the chosen soundproofing system cleverly channels the discordant energy. That intelligently directed noise then dissipates when it reaches an energy distributing core. Of equal importance, though, the elected dampening material must effectively absorb this artfully directed aural discharge. On that note, what materials work best here?
Existing Construction Materials
Thermal insulation has just enough noise dissipating talent to handle the first wave of auditory force. The thermally efficient mineral wool combines with soundproof plasterboard and cellulose fibres to really arrest the harshest rackets, be they street noise or the sounds of heavy shoes in a neighbouring apartment. Installed by building contractors, the construction materials fill wall voids. However, this isn’t a targetted noise cancellation system. Foams and thermal insulation wools are designed as building buffers, not as an advanced noise suppression solution.
Shaped into square panels, these bubble-filled puzzle pieces are typically covered in sound-attenuating wedges and grooves. Unlike the building materials mentioned above, foam panels are manufactured out of specially formulated polyurethane and polyester substances, chemical polymers that are designed to cancel out specific frequency ranges. Foam panels are found in recording studios, sound isolation booths, and places that absolutely demand a powerful noise cancellation system.
Noise Shushing Textiles
This is the most flexible noise dampening strategy. And all it takes to really actualize this fabric-based noise suppression system is a little weaving wizardry. Densely woven fabric blankets obviously act as capable sound dampeners. They stop echoes, kill cold reverberations, and they generally warm spiky noise profiles. However, the power of a fabric panelled solution is better realized when it’s expertly engineered. In other words, we layer the differently intertwined fabrics. A thin and lightly knitted fabric acts as a control threshold, then there are spaces between the following layers. They mitigate the vibrational energy until the weakened noise arrives at a foamy core. Blended fabric panels take noise management technology to a whole other level.
It takes a practised hand to select truly effective noise dampening materials. The construction material option works well at first, but it falls flat when high amplitude noises storm past the insulating wools and foams. Next, there are viscous compounds and structural decoupling systems to absorb the sound energy. However, it’s the fabric and specially formulated polymer systems that have really transformed this industry. Loaded with specially designed textiles and open-celled polymers, these fine noise dampening materials support intelligently engineered form factors.
