  • Personal Noise Solutions for Miners

    Throughout the working day, miners are continually exposed to varying levels of noise which can result in hearing loss. For safety reasons it is important to monitor employees’ noise exposure and Cirrus Research has created such a device in the form of the CR: 110A doseBadge. The Cirrus Research doseBadge is the original wireless personal noise dosemeter. It is the ideal tool to carry out ...

  • Reduction of roof rack noise and vibration

    The noise and vibration design of automotive add-on component roof rack was investigated. Different modification options were evaluated which include mounting location alteration, mounting damping change and material revision. Results from experimental modal analysis and sound pressure spectrum measurement in a wind tunnel indicate the direction of design modification for reduction of the roof ...

  • Recent research on vehicle noise and vibration

    Vehicle noise, vibration and harshness (NVH) is usually among the top five attributes in terms of its priority in the design of automotive vehicles. Its priority in other types of vehicles (e.g., aerospace) is also important. Like other attributes of safety, performance, dynamics, fuel economy, NVH has to be considered closely in the design process. This manuscript presents a summary of recent ...

  • Prediction of noise from track systems

    A practical approach is presented for the prediction of noise level generated by a track system at the design stage of a tracked vehicle. Rayleigh's surface integral is adopted for relating the acceleration of a track link chain in the time-domain to the radiated acoustic pressure of the exterior noise. The sound pressure levels of the noise generated by the vibrating track system are calculated ...
