Applications
Besides developing products and services, Munisense also handles the operational processes to keep applications running, like network monitoring and maintenance. We also develop OEM (Original Equipment Manufacturer) products. Please find some examples of our projects below:
The city of Leuven in Belgium limits noise nuisances from nightlife for its citizens and prevent damage to the hearing of the nightlife participants. The city has issued regulations that require establishments that play loud music to limit the sound levels and monitor these levels continuously. Munisense supplied the noise monitoring system to about 100 establishments and provides their management and the city with compliance data. The system consists of a sound meter, a display that shows the real-time sound levels, and an on-line portal to view violations and historical data.

The Wareco Water Data (WWD) is a turn-key service from Wareco Ingenieurs in the field of managing groundwater networks and monitoring groundwater during construction and replacing sewer lines.
Our equipment, cloud platform and services is Wareco's added value to their engineering services.
Noise monitoring in combinatie met nudging technieken heeft geluidsoverlast voor bewoners in het uitgaansgebied van Leuven sterk gereduceerd.
Onze noise monitoring stations (geluidmeters) die naast alle
gebruikelijke geluidparameters ook geluidsherkenning leverden werden gekoppeld aan nudging systemen. Het ingestelde geluidniveau in combinatie met gedefinieerde
geluidherkenningsparameters werd
gebruikt als trigger voor een scala aan nudging technieken.
Het meest effectief bleken de nudging boodschappen die direct op straat werden geprojecteerd aan de overlast veroorzaker(s).
Deze lichtprojecties zorgden voor een verlaging van de geluidsoverlast
met 30%. Deze slimme technologie helpt de Leuvenaars aan een betere nachtrust en een gezonder leefklimaat.
News
In vervolg op de eerdere projecten bouwen Leuven en Gent verder in "Nudging down night noise".
De twee grootste studentensteden gaan op verschillende locaties het nachtlawaai meten en herkennen om een breed zicht te krijgen op nachtelijke geluidsoverlast. Hiervoor wordt een geluidsherkenningsmodel gebruikt.
Daarnaast zoeken beide steden ook naar een gemeenschappelijke basis om nachtlawaai te meten en te beschrijven. Stad Gent legt hiervoor de objectieve data uit de metingen van onze noise monitoring stations naast de akoestische modellering.
Bovendien gaan beide steden nachtlawaai preventief aanpakken met nudgingtechnieken. Leuven kijkt naar de opschaling van de projecties en het aansturen van de openbare verlichting. Daarnaast worden ook nieuwe nudgingtechnieken onderzocht.
Beide steden gaan, naast de objectieve data uit de metingen, aan de slag met subjectieve data van bewoners over geluidsoverlast.

We relieve many provinces, municipalities and institutions -
with or without a partner - of the management and maintenance of
groundwater networks.
The Municipality of Haarlem also awarded us the management and maintenance of their groundwater network.
Socotec Geotechnics, our
partner for the field work for this project, has now equipped the 113
measuring points of the Haarlem municipal water network with our
telemetric groundwater meters.
Our equipment measures
the groundwater level at least once every hour and sends the measurement
data to our powerful data portal at least every four hours.
Taking
into account the current barometric pressure at that location and the
relevant data from the KNMI weather stations, the measurement data is
automatically converted to mNAP.
The measurement data is then
automatically validated and visible to the Municipality of Haarlem in
their user portal. Naturally, this groundwater monitoring data will then
be supplied to the Dutch governmental "BRO" (basic subsurface
registration).
Thus we accurately monitor groundwater levels so
that the Municipality of Haarlem has a good indication of when and
where measures must be taken.

The first group of field workers received the certificate for our Fieldworker Day 2024 on October 16: For consistently good quality installations and groundwater measurements.
Source holders (water well owners) are becoming increasingly strict with regard to data guarantees and data quality. Because we realize that fieldwork is crucial for this quality and guarantees, we initiated the Day of the Fieldworker.
We also used this day to present techniques that we expect to improve quality and guarantees, without taking more time.
Specifically, this concerns TritoSense with manual measurements at mm level, improved air pressure compensation and monitoring well caps that keep rainwater and dirt out while manual measurements are possible without disrupting the measurement setup.
The group of field workers who participated in the Day of the Field Worker on October 16 have at least taken a step forward towards better water data.
Day of the Fieldworker: For consistently good quality installations and groundwater measurements.
Over the past 10 years, managers of groundwater monitoring networks have imposed stricter requirements on the accuracy with which groundwater levels are measured.
One of the aspects where qualitative gains can be achieved from water data is during the installation of the now very accurate equipment in the field.
We noted that with current measurement methods it is difficult for field workers to meet current tender requirements.
Because how do they ensure the smallest possible deviation between the actual and the manually or automatically measured groundwater level of a measuring point in your measuring network?
Tomorrow, during our Fieldworker Day, we will inform and train fieldworkers.
For consistent and high-quality installations and groundwater measurements.
More about this tomorrow!
Our meters will be moved from the Floriade to event locations in the Municipality of Almere (NL). Permanent noise monitoring gives government and residents control over noise.
How?
Permanent monitoring of noise pollution can lead to a reduction in the most important forms of noise pollution. It enables competent authorities to get a grip on noise pollution, while it contributes to citizens' feeling of being heard and their involvement contributes to a healthier noise environment.
Why?
In the Netherlands, government agencies receive more than 500,000 noise complaints every year. A significant number of these are related to current nuisance caused by music events, catering, industry, construction, night noise, tourists, sports, loading/unloading and animal sounds.
An effective reduction of more than 30% of this nuisance is possible under the following conditions:
- Awareness of the perpetrator: It is essential that the perpetrator is immediately aware of the nuisance that is being caused.
- More than 90% of the perpetrators, such as catering visitors, music event organizations, industrial companies, motorcyclists, sports facilities and entertainment venues, are prepared to take measures as soon as they are aware of their impact.
- Transparency and continuous insight: All parties involved must have transparency and continuous insight, not only into trends but also into the direct effect of measures taken. Objective insight into the nuisance contributes to a new sense of standards.
- Encouraging self-regulation: Active stimulation and facilitation of self-regulation, for example by making noise transparent and open to discussion, promoting participation and including it in local regulations. The new Environmental Act offers opportunities for this approach.
In addition to self-regulation, permanent monitoring speeds up your complaint handling processes. After all, you always have measurement data available. Advanced functions in the measurement platform, such as identification of noise sources, location and the degree of exceedance or nuisance at homes, support the analysis and enable you to directly address noise generators, such as industry, about the nuisance they cause. And all this affordable and with a very low cost of ownership.
Would you like to know more about how you can achieve this reduction of noise complaints and a healthier living environment?
Call or email us, we are happy to brainstorm with you about this.
