The dual-axis air speed sensor from FT Technologies adopts a digital anemometer-based solution by being able to estimate airspeed incoming from any direction using an innovative acoustic resonance-based technology. The airspeed magnitude and direction allow the INS to estimate horizontal air speed in the longitudinal and lateral axis. ...
Abstract Ceramic strip resonators with rectangular cross-section have been made with aspect ratios (width to height ratios) from 0.1 to 30 . ...
Wheel–tyre structure and tyre acoustic cavity resonances have been identified in literatures as the culprits. In this paper, a comprehensive review will be made to tyre–road noise studies and specifically to the acoustic cavity resonance effects and countermeasures.Keywords: tyre–road noise, modelling, tyre ...
The effect of flow on the acoustic characteristics of a Helmholtz resonator is investigated experimentally. An impedance tube set-up has been modified to facilitate the measurement of transmission loss in the presence of mean flow. Acoustic impedance of the resonator is also measured with and without flow, enabling the analysis ...
Impact of mean flow on the acoustic attenuation performance of a Helmholtz resonator is investigated computationally. ...
The booming noise in an all-terrain tractor cabin is studied in this research via a numerical structural-acoustic approach. Cavity acoustic resonances of the cabin are evaluated, and the acoustic resonant frequencies are identified and quantified in the research. ...
