In some municioalities noise pollution is becoming a severe problem. Many citizens are exposed to various different source of noise, which affect their quality of life as well as their health.
One typical example example for such noise events are open air concerts. Often noise exposure occurs during night and therefore not within the authority's regular working hours. Only suitable automatic monitoring stations allow for an effective method to capture such events.
The web-based long-term monitoring system MUNISENSE provides authorities, administrations and companies with all means to atomatically and continuously measure the current noise pollution level as well as further environmental parameters, if needed, at a large number of long-term measuring locations. The measured values are stored centrally and in real time using the internet technology. In this, safety is provided by storing the data as well as by protecting the personal interests and privacy of the individual citizens.
The MUNISENSE monitoring network consists of an arbitrary number of autonomous outdoor noise mornitoring station in permanent operaation, which are connected to a central server through a wireless network.
The measured values are continuously transferred to the server and are accessible to the different users through a web portal and the administration of useres' righs allow protection of the interests and the rights of each individual user.
A pubilc presentation of current noise measurements is an efficient means to improve acceptance of noise emitting events such as open air concerts or major sports events wihin the municipality. Combined with background information on the events this helps to de-escalate possible conflicts with the residents.
For noise measurement the SINUS MUNISENSE system uses the modified hardware platform of the Tango sound level meter, offering accuracy class 1 according to IEC61672.
The Tango Monitoring station meets all requirments of the following fields of application:
- Monitoring traffic and industrial noise
- Monitoring neighbourhood noise / noise from recreational activities
- Monitoring noise at work.
The low power consumption of the sound level meter and the additional communication units allow battery operation on the internal battery for up to 100h. The measured data are send to the central server via ZigBee wireless network (for several stations in the immediate vicinty) or via 3G moderm.
The data are available for further use through a web interface. An individually designed website offering the possibility to grant differentiated user rights allows to display and analyse the data anywhere. Apart from the instantaneous sound level values at each measuring location, the level values of the preceding days as well as the audio data – for listening in – are provided. An SMS or e-mail alert in the event of level exceedance is an integral part of the system.
Apart from the purchase cost, the installation costs are a major factor.
The Tango_NMS stations allow permanent outdoor installation. Due to their low weight and small dimensions installation on public lamp poles is possible. The low power demand combined with the integrated battery and charger unit enables direct feeding from the street lights. Alternatively the stations may be powered by a small solar panel (30 x 40 cm).
Due to wireless data transmission no wiring or earthwork costs incur ! Additional stations may be integrated into the system without problems at any time.
PTB Type approval for the device Tango_NMS has been requested (for German legal calibration). The INSIGHTNOW™ server created by the company Munisense is used. The optional installation of the server at the customer is possible.

The combination of the monitoring system MUNISENSE and the post-processing software AUDITOR allows the convenient analysis of noise pollution levels according to the German Technical Instructions on Noise Abatement (TA Lärm).
