Acoustic microscopy and impedance analysis have emerged as pivotal tools in the non‐invasive investigation of biological tissues. By utilising high-frequency sound waves, these techniques ...

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 ...

Recently, the research teams from Tongji University and The Hong Kong Polytechnic University demonstrate that a compact broadband acoustic absorber can be achieved with coherently coupled 'weak ...
