Acoustic absorption is a fundamental parameter in the evaluation and optimisation of noise control within various environments. Recent advances have improved our ability to characterise how materials ...

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 ...

This latest accomplishment joins the company’s previously secured ASTM certifications, enhancing the features and expanding the end-uses for its microalgae-based bio-cement and bio-concrete. BOULDER, ...

Sound absorption Incoming acoustic waves induce relative movements among the fibres, initiating the triboelectric effect within overlapping regions. The generated charges are dissipated through ...

Good acoustics in the workspace improve work efficiency and productivity, which is one of the reasons why acoustic materials matter. The acoustic insulation market is already expected to hit 15 ...

Recently, National Science Review publishes the latest study led by Prof. Daining Fang (Beijing Institute of Technology), Prof. Li Cheng (The Hong Kong Polytechnic University), Prof. Yue-Sheng Wang ...

Acoustical comfort is a critical element of interior design that should never be neglected, especially in shared spaces such as restaurants, convention centers, museums, sports halls, and many others.

Sound, when emitted by a source — whether a person or a piece of equipment — propagates in all directions through space, being reflected, absorbed, transmitted, or diffracted as it encounters surfaces ...
