    Noise monitoring solutions for sound intensity mapping

    Sound Intensity is the measure of acoustic energy passing through a unit area. By integrating over a surface enclosing an object under test, you can calculate the object`s sound power. This can be done regardless of background noise, allowing convenient, in situ measurements of sound power. Other advantages of sound intensity measurements include the ability to determine the directionality of sound, and to quickly localise noise `hot spots`. Mapping software takes this a stage further by providing you with a contour map of noise levels to provide intuitive documentation of noise problems.

  • Noise and vibration monitoring for city monitoring

    Noise has become the primary source of environmental disturbance. In 2002, the European Union took decisive action in the form of directive 2002/49/CE relating to the assessment and management of environmental noise. Through the use of strategic noise mapping, every urban community must implement an action plan to combat noise pollution. The monitoring of noise levels in urban environments is therefore an essential factor.

  • Environmental Noise Monitoring

    The XL2 Sound Level Meter provides the dedicated solution for monitoring environmental noise in industry and communities. It measures levels and detailed spectral information in parallel and stores the data on an SD card for post-processing and reporting. A linear audio file (wav-file) may be recorded for detailed simultaneous analysis. The type approved class 1 sound level meter offers a flexible handheld instrument with accurate and reliable measurements. Data recording can be scheduled to occur at pre-determined times or automatically triggered when pre-determined levels are exceeded. Applications: Unattended noise monitoring stations (mobile or fixed installations) Annoyance assessment of noise according to ISO 1996-2 Construction noise measurements meeting the Section 61 notice (UK) Urban noise monitoring and noise mapping according to directive 2002/49/EC Verifying boundary noise level emission Advantages Handheld and compact design for field applications and stand-alone oper

  • noise3D online

    noise3D online enables commercial and industrial users to assess noise levels with the latest available propagation programs, without having to purchase expensive software. Instead, the 3D modeling software Trimble Navigation SketchUp or Google Earth (Pro) are used as interface. You can use your own planning documents, such as scanned maps for digitization, or transfer data from Google Earth for a simpler option.
