Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous ...

The fixed acoustic characteristics of unit-cell cavities fundamentally limit the broadband sound absorption performance of cavity-type sound-absorbing metamaterials. This study identifies that the ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

Long-term exposure to low-frequency noise can cause numerous health problems, but the solution may be found in an unexpected object, a pingpong ball. Conventionally thought of as the hollow plastic ...

While most sound-dampening panels are all function and little form, these acoustic panels from Dekiru actually look great. These one-foot hexagonal panels fit together neatly for noise reduction in ...

The quality of home TV sound has improved with DSP trickery and soundbars plus a large pool of younger consumers who have invested in better sound for their gaming experience. So there is no doubt ...
