Possible Solutions

Construction

Construction activities can be a significant source of noise and vibrations and as a consequence lead to complaints by residents or damage to buildings or sensitive equipment. Our systems are very well equipped to monitor noise and vibrations (3 directions) and presenting the results in real time. With Noisenet's interactive internet pages governing bodies, construction companies, consultants and residents can be properly informed with information geared specifically to each group. Our experience has taught us that with appropriate communication the number of complaints can be decreased and problems can be prevented.

For the construction company the systems provide peace of mind and being able to focus on core activities. Due to MP3 recordings and warnings via email or SMS of threshold exceedances, causes for complaints or potential damage can be instantly addressed and mitigated.

Governing bodies can keep a close eye on whether construction projects adhere to their bylaws and regulations and show that they take the interests of all at heart.

Due to more transparency residents feel that their interests are taken seriously and will be less prone to complain.

Industry

In certain situations the proximity from residents or noise sensitive assets to industry can be cause for unwanted situations or annoyance. Continuous unmanned noise monitoring could be a tool to assess whether noise limits are respected and whether complaints are valid. Since industry consists of a broad range of companies, made to measure solutions are required taking into account quality, know how and a fair price. We do not only know a lot about monitoring, but are also experienced in industry and regulations so we can provide you with a well though out approach. Reports can show instantly whether companies are complaint with their noise limits and as a result whether complaints are valid. This provides clarity.

In cases where complaints arise due to noise incidents, unmanned real time monitoring is a great solution. Since incidents do not occur at a planned moment, using our systems will reduce man cost and will capture the actual events when they occur. Including simultaneous sound recordings provide a valuable tool to pinpoint what actually happens during the incidents.

Rail Traffic

Noisenet can provide monitoring services for Trains and Light Rail Transportation, not only to assess noise at receptors but also as part of Asset Management. It is possible to design smart systems in which train movements can be pinpointed and coupled to specific train stock. Changes in noise emission of certain train stock could be an indicator that maintenance is required. This could ensure timely maintenance, reduced cost due to less breakdown and downtime of equipment and improved longevity. These systems would be designed to measure including the way the data are reported. Of course vibration sensors, weather sensors, audio, video or photo recordings could be integrated in such a system if required or desired.

Wind Power Facilities

Wind power facilities are seen as “green” because their source of power is renewable and that is considered a good thing for the environment. However if placed near dwellings, residences might have a different point of view. Residences in the vicinity could raise concerns about noise in the planning stage or once operational.

Noise concerns due to wind turbine noise are strongly linked to weather conditions (wind speed and wind direction). Combining noise monitoring with simultaneous weather monitoring could provide the solution to monitor the local situation. Complaints can be matched to specific weather conditions and thus be addressed more adequately. Long time noise monitoring can also provide inside in the actual operating conditions of the wind turbines.

Vibrations

Vibrations can cause damage to buildings and equipment and are a cause of annoyance. Vibrations are not always preventable, but could be monitored so action can be taken before damage occurs and/or complaints and litigations arise. Noisenet systems measure three directional vibrations and use robust vibration sensors instead of geophones. Geophones have the disadvantage that they their intrinsic frequency is between 5 and 10 Hz, which is a frequency that is important in many cases. The monitored values can be linked to regulatory threshold values and alarms via email or SMS can be generated in case of exceedances. Report can be made to measure to report the values and periods that are of interest to you. Combining the vibrations measurements with simultaneous audio and video recordings will provide clarity over the source of the exceedances or incidents.

Vibration monitoring can be performed as part of regulatory compliance but is also a valuable tool in cases where constructions or part of constructions radiate noise and the pathways need to be detected to resolve the issues. Also in buildings that house very sensitive equipment like medical instruments, precision weighing, electron microscopes, precision lasering and eye surgery for instance minute vibrations can have grand effects. Industrial equipment like large pumps or construction activities, trains and light rail applications are all examples of areas where vibrations can have a significant impact on the process or surroundings.

Weather Data

Measured noise data can be enhanced by connecting it with simultaneously measured weather data. In certain cases that would also be a requirement and it is for certain an aid in the interpretation of data. Some common parameters that are monitored are temperature, windspeed and wind direction, precipitation, air pressure and relative humidity.
