sound transmission

In vibration-mediated suppression mode, the fabric could reduce sound transmission up to 75 percent.

This result from a study by Western researchers, published today in the high impact journal PNAS, contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.

"It can be broadened to achieve various functions similar to other metasurfaces. These functionalities encompass sound focusing, unconventional sound reflection, sound transmission manipulation, and more."

However, the scientists said changes to ocean temperature and chemistry also can change sound transmission.

Sound transmission through shared walls is a common problem, so it’s no surprise that there are many products available to help.
