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 ...

We've come a long way since the days of pouring wax into our ears to block out siren songs. A team of researchers at Hong Kong University of Science and Technology have developed a sound-cancelling ...

Absorbing low frequency sound is a big job, or at least, a job for big things. Acoustic absorption systems require big resonant cavities with large amounts of heavy damping material and significant ...

Researchers have engineered a silk fabric that can suppress noise by either generating sound waves that interfere with the noise or by blocking vibrations that are key to the transmission of sound.
