  • Weather Data for Noise Monitoring

    “Weather conditions are the single largest variable factor in how sound travels over large distances,” says Steve Bilawchuk principal partner and engineer at ACI Acoustical Consultants Inc. “Wind speed and wind direction are of crucial importance.” ACI is an acoustical engineering consulting company based in Alberta, Canada, which uses ...

  • Case study - Wall leakage testing in the lab with acoustic camera

    Problem Facade insulation testing is usually performed by using a loudspeaker in the sending room, and record the sound pressure level (SPL) with microphones in both the sending and receiving room. The difference in SPL adjusted for the size of the dividing wall element will then give an estimate of the sound reduction quality of that element. However these measurements will not say ...

  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

  • Noise Mapping in Lille

    Lille, with a population of 1091 million inhabitants is the 4th largest agglomeration in France after Paris, Lyon, and Marseille. Situated at the heart of a network of 464 km motorways connecting six European cities (Brussels, Bonn, the Hague, London, Luxembourg and Paris), the metropolis of Lille also has the densest railway network of France after Paris. Pascal Thomas and his team of 8 ...

  • Noise mapping of roads in England

    Landmark Solutions, the UK provider of geospatial information, solutions and services, was selected by DEFRA as the prime contractor to carry out noise mapping for the Potteries area of the West Midlands. This work forms part of the Government’s National Ambient Noise Strategy (NANS), part of which is focused on mapping noise levels from roads, railways, aircraft and industrial sites across ...

  • Measuring Road Traffic Noise

    As part of an overall measurement programme to monitor road traffic noise in Århus (Denmarks second largest city), the Local Authority set up a noise measurement station on one of the major approach roads to Århus Harbour. This noise measurement station continually measures noise levels and can give a round-the-clock picture of noise level variations. Like most other districts, Århus Local ...

  • Urban Noise Monitoring in Madrid

    Dynamic mapping helps Madrid improve the quality of life for her citizens and visitors alike. With its 3 000 000 inhabitants and 2500 km of streets, Madrid is an excellent example of what can be done to improve human comfort related to urban noise. Since the late 60s, Madrid City Council has been working on noise problems. During this period, global environmental analysis has focused on how ...

  • Noise mapping of industrial sources

    Noise is often one of the environmental variables where it seems more difficult to guarantee full compliance with legal limits in complex industrial situations and/or in other multi-source environments. This paper describes the application of noise mapping techniques to industrial sources, such as factories, power plants, wind farms, showing the potential of its use, both at the design stage as ...

  • Autonomous data acquisition system for Paks NPP process noise signals

    A prototype of a new concept noise diagnostics data acquisition system has been developed recently to renew the aged present system. This new system is capable of collecting the whole available noise signal set simultaneously. Signal plugging and data acquisition are performed by autonomous systems (installed at each reactor unit) that are controlled through the standard plant network from a ...

  • Methods for Removing Signal Noise from Helicopter Electromagnetic Survey Data

    A geophysical analysis was conducted over the abandoned T&T subsurface mines and portions of the Muddy and Roaring Creek watersheds in northeastern Preston County, West Virginia. The data were collected using helicopter-borne measurements of frequency-domain electromagnetic (FDEM) conductivity (390, 1555, 6254, 25,800, and 102,680 Hz). Noise was a significant issue in the lowest frequency EM ...

  • Environmental Noise (Booklet)

    About this booklet This booklet deals with environmental noise − for example, noise from industrial sites, road and rail traffic, airports and fairgrounds. It does not cover related issues such as building acoustics, building vibration or domestic noise. Neither does it cover human response to vibration nor industrial uses of sound and vibration measurements. Please contact ...

  • Noise in Europe 2014

    Noise pollution is a growing environmental concern. It is caused by a varied number of sources and is widely present not only in the busiest urban environments, it is also pervading once natural environments. The adverse effects can be found in the well-being of exposed human populations, in the health and distribution of wildlife on the land and in the sea, in the abilities of our children to ...

  • Noise Monitors and Meters

    Sound level meters Description and ApplicationsThe sound level meter is a lightweight instrument for the measurement of sound pressure level (SPL) in decibels. All ANSI-approved meters meet minimum requirements that include an A-weighted network, a slow-response meter characteristic, and a fully graduated scale with measurements ranging from 80 to 130 dBA. The Type II meter is most frequently ...

  • 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. ...

  • 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 ...
