Bad room acoustic is an increasing concern in the modern building designs, as the long-term and repetitive form of acoustic nuisance can cause serious health issues e.g. sleep disturbance, stress, hypertension, hearing impairment and many other serious ailments. Current solutions for optimal room acoustics range from the use of porous material to the implementation of ceiling tiles and acoustic panels to adequately reduce noise to healthy levels. However, these conventional solutions are relatively expensive, unattractive in design and mostly made from ecologically harmful materials. In addition, they usually consume a significant amount of space, reducing substantially the room’s size. To address this problem, IDEE& DESIGN has developed SOUNDCOMB+, a natural sound absorbing 3D panel made of ecologically sustainable materials that reduces up to 95% the sound in indoor spaces. It is the first dual functional acoustic panel designed to be imbedded in the wall, resulting in a customizable aesthetic object that absorbs the annoyance sound from the room without loss of space, while avoiding sound transmission through wall insulation.
