  • Verification of CFD tool for simulation of cavitating flows in hydraulic systems

    Cavitation is an undesirable phenomenon in hydraulic systems, as it causes erosion and noise. The main difficulty in cavitation prediction when using Fluent software is lack of an openly accessible tool for implementation of a freely chosen homogeneous cavitation model. In this paper the main challenge is to make such a tool, user defined function (UDF). The second challenge is to use a ...

  • Determining the Right Cable Length and Output for a Sensor

    If you’re monitoring a bridge or automating a machine, a high precision sensor is a great solution, but it’s no good if the output signal can’t reach the data logger. Depending on what you need to measure and what environment you’re in, determining how long your cable must run can be crucial. High precision sensors offer three common output types: analog, digital and ...

  • Is a background noise survey worth doing? - Case Study

    As a plant owner or designer you will logically try to keep construction costs down wherever possible. So noise control features can easily be sidelined as an “optional extra” to be added later if the need arises. You might also be confident a new industrial plant will comply with all regulations on completion, but that doesn’t mean a future neighbour won’t complain about ...

  • NoiseNews: Something Fishy Going on in British Waters?

    The seas around Britain may be getting too noisy. So noisy in fact that fish species such as cod and haddock are having difficulty communicating with each other. If their chatter is being obscured, it could affect their ability to breed at a time when stock numbers are recovering. It has long been recognised that large marine mammals are susceptible to noise pollution – as ...

  • Mitigating the effect of weather on environmental noise measurements

    Many factors play a part when creating a reliable environmental noise assessment. This paper provides a practical look at the effect of weather conditions on sound levels to raise awareness of the importance of meteorology in noise measurements. It references requirements for measuring meteorology in BS-4142:2014 and compares them to legislation from other countries. It also covers how variations ...

  • How does living with aircraft noise affect wellbeing? A study of UK airports

    Airports are associated with air and noise pollution and may, therefore, reduce the quality of life of local people. This study assessed the link between aircraft noise and subjective wellbeing, using data from 17 English airports. The authors conclude that living under flight paths has a negative effect on people’s overall wellbeing, equivalent to around half of the effect of being a ...
