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 deliver ...

Deep-subwavelength acoustic absorbers have received great attention due to their scientific and application values. Porous materials and micro-perforated absorbers, as the most conventional solutions, ...

With increasing demand for exploration and utilization of marine resources, achieving direct and efficient communication between water and air has been an urgent need. Sound waves, as the only ...

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 ...
