Fundamental Concepts In Acoustic Transducer Array Design

Abstract Ceramic strip resonators with rectangular cross-section have been made with aspect ratios (width to height ratios) from 0.1 to 30 . The short and open circuit resonant frequencies have been plotted as a function of aspect ratio and show good agreement between experiment and a simple coupled mode theory. The effect of loading these resonators acoustically with solids and liquids has also ...

A survey of wheel tyre cavity resonance noise

Noise, vibration, and harshness (NVH) are synonymous with quality factor in automotive engineering. This quality factor is influenced by the internal noise such as engine noise, and external noise ...

Hail and Ice Pellet Add-on Sensors

HIP-100 is an acoustic sensor developed as an add-on option to the OWI-series Weather Sensors, giving an even greater range of weather data collection. It is difficult to discriminate a solid ice particle from a water droplet using optical techniques alone. When an ice particle hits a metal surface, the noise caused by the impact is clearly distinguishable from the impact of a water droplet. ...
