Solutions for environmental and immission control - software, simulation, analysis

"Awareness of health, quality of life and sustainable development is on the rise. At the same time, growing cities, dense traffic and new technologies are increasing the demands placed on noise control. With our cloud-based software solutions IMMI Hub and dBEL, we are driving the digital transformation of noise protection – delivering measurable improvements in precision, efficiency and accessibility. This is how the next generation of noise control is taking shape: smarter, more connected and accessible to new user groups. For an environment where people and technology coexist in harmony."

SUCCESS STORY

STIEBEL ELTRON: "dBEL.HVAC makes visible how quiet our heat pumps are"

_____________

“The heat pumps work so quietly that even your neighbor will like them.” This statement can be found on the website of one of the largest heat pump manufacturers in Germany: STIEBEL ELTRON. What could previously only be proven in consultation with standard values and complicated tables or only after an installation, the company and its specialist trade partners will in future be able to prove and illustrate with just a few clicks – with the help of the dBEL.HVAC cloud application.

"We have been using IMMI since 2000. Before purchasing, we compared all relevant products on the market.
The decision to purchase IMMI was based on the very logical setup and technically clear program operation.
We also appreciate the competent, quick and effective problem solving via hotline inquiries – definitely a big plus for Wölfel.
To summarize: IMMI – We would definitely go for it again."

"For almost 25 years now, the IMMI software package has been an extremely useful and helpful support
for me in the computer-aided solution of a wide range of sound-related problems.
It also fills me with pride to see that a few of my suggestions have been incorporated into IMMI.
All the time you and your colleagues have been helpful not only to me but to all IMMI users in case of questions and needs."

“We frequently use the IMMI model to predict the sound pressure level effect on the nearest houses
to new industrial activities, crushers, gas engines,... Afterwards we always take measurements
to check the results. The IMMI model is well suited to make these predictions (in other words
the measured sound pressure levels are almost equal to the calculated sound pressure levels).”

“We use IMMI to evaluate the effectiveness of noise barriers where the possibility to import a wide range of input
data is necessary. The simulations made in IMMI are presented very clearly and are visually appealing.
This means the results can be understood by both professionals and people who are new to the subject.
The user friendly interface is easy to work with and allows for a fast learning curve for new users.”

“The biggest advantage for us is that we can now visualize the acoustic benefits
of our heat pumps thanks to dBEL.HVAC – this is a huge benefit in sales discussions with
prospective customers.The conformity of the forecast with all applicable standards creates trust and
the noise maps make the results understandable for everyone.”
