Ultra-thin sound blocker cuts traffic noise dramatically

If you live near a busy street, this new breakthrough from Switzerland could offer some long-awaited relief. Researchers at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have developed an ultra-thin traffic noise absorber that significantly reduces sound levels while occupying just a fraction of the space required by traditional materials.

The new absorber is only about 2.1 inches thick, yet it performs on par with much bulkier products, such as rock wool. Even more impressively, it can be customized to target specific types of noise, making it ideal for a variety of indoor and outdoor settings.
