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 ...

Acoustic Impedance: The complex ratio of sound pressure to particle velocity at a surface, reflecting how much resistance a material offers to the passage of sound waves.

Quantitative acoustic microscopy (QAM) uses ultra-high-frequency ultrasound (>200-MHz) to create two-dimensional maps of acoustic and mechanical properties of tissue at microscopic resolutions (<8μm).

In pursuit of a broadband sound-proofing yet airflow-permeating performance, the mechanism of acoustic consecutive Fano resonances was presented to broaden the sound insulating bandwidth [31–36]. For ...

Continuous infrasound (low-frequency acoustic energy) monitoring is now established in Yellowstone. And the method is detecting activity that goes beyond geyser eruptions.

The impedance of the NS-2000A, as measured by Newport Test Labs and shown in Graph 4, shows why Yamaha has elected to specify a nominal impedance of six ohms for the design, because the impedance ...
