Urban Noise Monitoring Applications

Noise monitoring solutions for urban noise

The sounds in a city are central to our quality of life. Constant exposure to noise effects both our physical and psychological health, and our ability to learn and communicate.

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

Noise and vibration monitoring for race circuit monitoring

Certain leisure activities, and motor sports in particular, are a source of elevated noise levels. They cause significant disturbance for nearby residents, particularly as such sites are being developed in increasingly densely populated urban areas.

Noise monitoring for railways and trains

Controlling and monitoring railway and train noise in residential and urban areas is a critical function of a railway. The noise generated can be dependent upon the engine, rail cars, rail construction, train speed, and the horn. Modern high speed trains have also created new levels of high frequency noise that create an acoustic disturbance that sounds like an aircraft going by.
