When you think of an acoustical material, what comes to mind? Maybe some kind of dark gray foam glued to a wall? Perhaps orange shag carpeting? Or how about those square-foot white, perforated wall ...

Acoustic and thermal insulation materials have become an essential focus in modern engineering, driven by the need to reduce noise pollution and enhance energy efficiency in buildings and vehicles.

Road noise has long been a problem in cars, particularly when traveling at speed on the highway, but it's even more obvious in electric cars, which don't produce engine noise that can help mask it.

Good acoustics in the workspace improve work efficiency and productivity, which is one of the reasons why acoustic materials matter. The acoustic insulation market is already expected to hit 15 ...

During the Institute of Scrap Recycling Industries’ (ISRI) 2019 Convention & Exposition April 8-11 in Los Angeles, the Spotlight on Plastics highlighted some unique products that are starting to ...

In our increasingly noisy world, it can be hard to find some quiet time. Now, a team of mechanical engineers at Boston University has developed a new device that is specially designed to block up to ...

Circular cotton is used to create colorful sound absorbtion tiles from Impact Acoustics. With only 12% of clothing materials being recycled and 92 million tonnes of textile waste being produced ...

So-called “acoustic metamaterials” are specifically designed to control and manipulate sound waves, usually for the purpose of dampening or transmitting sound. But such an acoustic device can only ...

Kyle Hyatt (he/him/his) hails originally from the Pacific Northwest, but has long called Los Angeles home. He's had a lifelong obsession with cars and motorcycles (both old and new). Noise vibration ...

Sound deadening material plays an important role in making cars comfortable and quiet, but most people don’t give it much thought. Nissan engineers are one of the exceptions as they’ve developed a ...

Figure 1. Ultrasound pulsed into a part by the scanning transducer is partly reflected by a well-bonded interface (at left); the remaining portion of the ultrasound travels deeper into the part. A gap ...
