    For an external source, the noise level equation is   Leq=LW-20Log(r)-11dB(A)   where r is the distance and LW the source power. However, for an industrial complex, the next equation will be used: ...

  • Canarina CUSTIC software · environmental noise modeling · algorithms 4

    In the railway case, we shall calculate the noise level in a similar way. For airports, we shall use the next equation Leq=Leq(300m)-20Log(r/300) where Leq(300m) is the noise level at 300m from the airport. This model performs satisfactorily for simple sound ...

  • Noise monitoring system appeals to Reno-Tahoe Airport`s neighbours

    Noise monitoring and reduction has been top priority for Krys Bart ever since she took the helm of the Reno-Tahoe Airport Authority (RTAA) a decade ago. As RTAA president and CEO, Bart wants Reno-Tahoe International Airport to be a ‘good neighbour’, as it serves more than 4.4 million domestic and international passengers each year. The airport’s location right in the centre of ...

  • What is Long Term Noise Monitoring?

    It might sound simple, but long term noise monitoring can mean different things to different people. There is no standard definition for what long term noise monitoring is, but here is a summary that covers the basics. I first presented this presentation at the IOA Eastern Branch meeting and wanted to share my thoughts on what classes as long term noise monitoring. I’ll also discuss ...

  • Noise Planning Software Used to Map Major EU Roadways

    Most countries have a national noise policy to protect citizens from undesirable environmental noise levels from road, rail and air traffic and industrial sources. The European Noise Directive for the Assessment and Management of Environmental Noise outlines a coordinated method to achieve noise reduction in large cities as a first step, followed by smaller cities as a second step. The ...

    Noise power (dB): This is the noise power at source position in decibels.   Airport options: We have two options: An aircraft landing/taking off at 300m or Daily average (number of airport operations in a day). ...

  • Airport Construction and Aircraft Monitoring example application – CR:243/1 case study

    Project Summary In this application a number of noise monitors were installed to measure the noise from a new international airport both during the construction and also when the airport opened. The noise monitors were located on buildings, in and around the centre of a large city. The Invictus Permanent Noise Monitor was chosen as each location was different and each installation needed ...

  • Accelerating with Bugatti

    When the Bugatti Owners’ Club established itself in 1929, its members didn’t really have too much to worry about when it came to issues such as road congestion and noise. But just as cars have moved on with the times so has the Club. The Club applies a strict noise level threshold for competing cars at their renowned meetings on Prescott Hill near Cheltenham, ...

  • Helping Volvo maximise uptime

    With the many challenges facing the automobile industry, such as shortened development times, Volvo is increasingly moving its Noise, Vibration and Harshness (NVH) development into computer simulation and modelling, with less traditional prototyping. A well-established customer of Brüel & Kjær, Volvo benefits greatly from the value added to their systems in terms of the minimised ...

  • PULSE FRC – frequency response correction compensation is a good thing

    Furthermore, increased flight operations can be conducted around more restrictive airports. The determination of an aircraft type’s noise is a complex process guided by documents such as: International Civil Aviation Organization(ICAO) Annex 16 – Environmental Protection, Volume I – Aircraft Noise Federal Aviation Administration (FAA)CFR14 PART 36 – Noise ...
