In the early days of noise protection, expert noise reports were still processed with a pocket calcuator.
Due to their interest in computers, Dipl.-Ing. Gert Braunstein and Arne Berndt, while working in an engineering office, came up with the idea that these calculations could be made easier with the help of a computer program. They put the idea into practice, with Gert Braunstein working on the technical side, and Arne Berndt on the programming.
They soon founded their own business, the "Engineering company for environmental protection - traffic planning - data processing Gert Braunstein Arne Berndt", in the house of Gert Braunstein in Leutenbach, Germany.
The computers used are computers of the 8088 series with mathematical co-processor, MS-DOS operating system, approx. 20 MB hard disk, a digitizer for input, dot-matrix printer and pen plotter for tabular or graphic output.
The identification mark is the "level chart" - a diagram that visualizes total noise and reflected noise. This was the inspiration for the company logo.
Presentation of the first coloured noise map at the annual conference of the German Society for Acoustics, "DAGA" in Bochum. At that time, the maps were printed with an electrostatic printer. Since then annual participation at the conference.
After the German reunification the number of customers in the "New Federal States" is growing.
Challenge to perform the nationwide noise mapping of the federal railways; successful realisation for the years 2007, 2012 and 2017. The second and third round of noise mapping 2012 and 2017 was carried out as a powerful team together with the project partners disy Informationssysteme GmbH and Pöyry Deutschland GmbH.
Since 2011 a cooperation with d&b audiotechnik GmbH, Backnang, one of the world's leading manufacturers of professional sound systems for concert halls/operas as well as for open air concerts.
The international distribution is now managed from SoundPLAN GmbH in Germany. Arne und Elizabeth Berndt withdraw from the operative business.
Building bridges to go together even stronger into the future! We remain true to this philosophy and continue to expand our solutions in the field of room acoustic planning in order to become even better for our customers.
Sarooma still stands for the fast room acoustic planning of simple rooms according to many national regulations. SoundPLAN's sound particle model allows deeper analysis in this area. Linkage between both products: the state-of-the-art sound absorber database from Sarooma.
