Munisense expands NL Alert
Every first Monday of the month the warning siren sounds at noon. Everyone in The Netherlands recognises the sound, but is it still sufficiently effective in the current digital world? Read more.
Quick and cost-effective integration of measurements and system control for businesses, governments and authorities. 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. For more information please see www.horecasense.nl (in Dutch).
Intelligent Smart City Lighting. The Eurel system, as implemented at the Havenspoor bicyclepath in Rotterdam, is an innovative real-time on-line dynamic light management system. The system transforms static lighting into on-line controllable lighting with the ability to adjust light levels to real-time needs. The result is energy efficiency by allowing low light levels when there is no need to illuminate, and safety by increasing light levels when necessary. The Eurel system uses all functionalities of our INSIGHTNOW™ platform.
The City of Amsterdam has investigated the indoor climate of its 360
schoolbuildings with our indoor climate meters. Based on the data from these CS4 measurement
sets, improvement priorites have been set.
Results of implemented improvements are also monitored based on objective measurement data from the CS4 meters in our INSIGHTNOW™ cloud platform.
The Rijn en IJssel Water Board will be measuring groundwater levels with Munisense water meters that use T-Mobile's NB-IoT infrastructure.
The Rijn en IJssel Water Board manages the groundwater and surface water in East Gelderland, the south of Overijssel and the southeast of the Veluwe. T-Mobile is one of the first nationwide coverage in the Netherlands and was closely involved in the integration of NB-IoT into our online platform.
The NB-IoT communication protocol is part of 4G and is ideal for monitoring groundwater. The NB-IoT protocol provides much better accessibility in places that are difficult to reach by radio. NB-IoT equipment can deal with lower signal strength compared to GPRS equipment. For the groundwater meters, which are often placed below ground level, NB-IoT is ideal. An additional advantage is that, thanks to NB-IoT, the meters use even less electricity and therefore the battery lasts longer.
This month, 47 NB-IoT groundwater meters will be active in the area of the Waterschap of some 200,000 hectares divided over 22 municipalities. The groundwater meters deliver measured values every hour and send them real-time via the T-Mobile NB-IoT network to our cloud platform. Thanks to the NB-IoT groundwater meters, the Water Board is given thorough insight into their groundwater levels. Simple, fast and real-time.
Every first Monday of the month warning sirens sound at noon. Everyone recognises the sound, but is it still sufficiently effective in the current digital world? The current national warning sirens will disappear in 2020.
Commissioned by the Ministry of Justice & Security, the DITSS Foundation in collaboration with Munisense, started developing a warning system that expands the current smartphone project NL Alert.
Warn, alert and inform
Behind the scenes work is being done on a new version of the warning system, that also clarifies the nature of the alarm situation. The system we developed was tested in the center of Eindhoven at the beginning of June. In addition to a number of signaling alarms, spoken messages were also broadcasted.
The loudspeakers can be controlled individually or by using cell broadcasting. Specific alarm messages can be broadcasted very locally - in just one or several streets or neighborhoods. Both residents and passers-by in that area get precise information about the nature of the alarm situation even when no smartphone is available.
Later this month the audibility and intelligibility of the system will also be tested at night. Then it will become clear whether the alarm system is also suitable for awakening people from their sleep and then informing them.

The much-discussed experience flight that took place on 30 May gave residents of the areas under the future flight paths of Lelystad Airport an idea of how much noise an aircraft will make.
Our noise meters registered the noise of the Boeing 737-800, comparable to the aircraft that will depart and arrive from 2020 at Lelystad Airport. The passages of the airplane could be followed live via munisense.live/belevingsvlucht.
The first results were reported to the ministry of Infrastructure on friday June 1: Results noise measurements (pdf file in Dutch).
This experience flight was also the topic in the media. A selection from the news:
NOS - 8 uur journaal 30 may 2018; the meters and measurements of our noise meters were shown on our online platform.
Nu.nl - 30 may 2018; one of the three articles that nu.nl published today.
RTL Nieuws - 30 may 2018; varying reactions about the noise level.
AD.nl - 30 may 2018; interview with the chairman of the control group belevingsvlucht and with the Ned. Stichting Geluidshinder.
Trouw - May 31 2018; Fingers point in the air. There is the 'belevingsvlucht' - with map with measurements (see below)
On 30 May a.s. the experience flight of Transavia takes place. In this way residents and other stakeholders also gain insight into the noise production of a Boeing 737 at low altitude.
The real-time noise measurements are carried out with Munisense meters at 16 measuring points in Gelderland, Overijssel and Flevoland right under the flight paths of Lelystad Airport.
At each measuring point a noise meter is installed that transmits the measured values in real time to our online INSIGHTNOW platform. The noise meter continuously measures the sound from the moment of installation. In this way the background noise is also well mapped. The maximum noise level is determined during the passage of the aircraft. After the passage, the measured values are once again checked (in some cases the recorded noise files will be listened) and validated.
The ideal balance between noise, noise and health. That is what many events struggle with. Obtaining a permit is more difficult due to stricter regulations. What to do?
A handy system that can provide stakeholders - ie organizer, DJ, municipality, enforcement and local residents - with live insight into noise levels during an event. Our mobile, wireless and affordable sound measurement system offers a solution.
The DJ or organizer can, thanks to the prediction function, vary within the limits and thus maintains a good deal of creativity. The usual complaints from local residents are decreasing and the visitors have a top event.
A win-win situation.
We are happy to tell you more about the possibilities of purchasing such a system or renting it.
The magazine Events & Showbizz 1 of 2018 devoted an article to our system. You can find it here.
