Bouncing Off Walls: Industrial Fan Noise Directivity Specification
What is Industrial Fan Noise Directivity? Industrial fan noise directivity is an indication of how the fan surroundings contribute to the sound level in the field. It is a small but important factor in specifying the right accessories, insulation, housing, and enclosures for noise reduction in your application. Because proximity to reflective surfaces amplifies sound, where you put your fan ...

Acoustic camera and beampattern
Abstract—The wavenumber-frequency response of an array describes the response to an arbitrary plane wave both in time and space. When the input consists of a single monochromatic plane wave, the response of the array is referred to as the array pattern or beampattern. Through the design of the array our goal is to have a directivity of the array as high as possible in a given direction, ...

Modelling of broadband noise radiated by an airfoil-application to an axial fan
In this paper, a modelling of the broadband noise radiated by an axial subsonic fan is presented and validated. It is an extension of Amiet's model predicting the broadband noise generated by an isolated airfoil. Two sources are analysed, incident turbulence interaction noise and trailing edge noise. It shows the dominance of the leading edge noise. The broadband noise directivity for axial fans ...

Ready for the future with CNOSSOS-EU!
The Environmental Noise Directive 2002/49/EC which appeared in 2002 raised the question among those who are “experts in noise” how noise mapping and noise action planning should be implemented throughout Europe. They all agreed that, in view of the completely different calculation methods in the European countries, the calculation results reached and exposure figures collected would ...

END noise mapping – the sustainable solution of the german federal railway authority, review to an outstanding
The Federal Railway Authority of Germany was tendering 2006 a sustainable noise mapping system to fulfil the needs of the END (European Noise Directive). The aim of the project was to develop a system which contains all required model data and results for the first level of the EU noise mapping. In addition the system should be an integrated software solution to explore the model data. It should ...

Controlling combustion noise in direct injection diesel engine through mechanical vibration measurement
The next generations of direct injection diesel engines have greatly improved their performances compared with petrol engines. However, one of the pending subjects is the noise and vibration levels, due to working cycle itself. The design effort to reduce the emissions of noise and vibration transmitted to the vehicle's driver could be lessened because of the assembly process variation. In this ...

Procedures to analyse noise maps in connection with noise action plans
After finishing of the noise mapping of the European Noise Directive1” the noise action planning follows. This part of the END-projects concerns with measures for noise reduction in general and in detail and information and collaboration of the public. In this process a huge amount of measures and alternatives accumulates. Therefore automatic working tools for evaluation of the measures and ...

Integrated noise calculation and evaluation according to the EU directive on environmental noise
The model data for acoustic calculations already contains essential characteristics for more in depth evaluation of the results (i.e. building heights, number of storeys, or ground space per storey). With additional information such as building usage and number of inhabitants, the evaluation and graphical representation of the results can be completed with only a small increase in expense. ...

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 ...
