Abstract: We report sub-wavelength resonant panels for low-frequency sound absorption by using the accumulation of cavity resonances due to the slow sound phenomenon. The panels are built by bricks of ...

Build a powerful subwoofer from scratch and unlock deep, punchy bass for your home setup. This video walks through the key steps, materials, and tips to get clean low-end sound on a DIY budget. If you ...

This paper reports an investigation of a new kind of material and its acoustical performance. The main component of this porous absorber is the ground tyre rubber (GTR) with different particle sizes, ...

THERE are two methods of measuring the amounts of sound absorbed by various materials. One is the reverberation method of W. C. Sabine, in which a specimen of the material to be tested is mounted on ...
