A system that absorbs 99.7% of all sound
Sound Absorption
Science and technology never stops advance towards the future…
And particularly in the field of sound absorption and/or isolation.
Here is a new development from Hong Kong University of Science and Technology that absorbs 99.7% of all the sound!
The new technique uses a pair resonators, built as a single layer and designed to naturally vibrate at the frequency of whatever they’re attached to (every object has a natural frequency, a function of its physical and material properties). Sound is largely cancelled out by one of the resonators: it provides a route for sounds to dissipate through, made possible by tuning its natural frequency to that of the thing it’s attached to.
Who is gonna silent the remaining 0.3% ?
