The Sarooma Team

Florian Fordermaier

Florian Fordermaier

Managing Director

I have been supporting Sarooma from a programming point of view for many years, working with Jörg Hunecke in the beginning and now having another strong partner at my side with SoundPLAN. Sarooma’s continued existence is thus assured and it can move into the future with further innovations.

Michael Gillé

Michael Gillé

Managing Director

Through my active involvement in standardization work and committee activities, I am close to development and also contribute my knowledge to Sarooma.

Thanks to my many years of experience in quality assurance at SoundPLAN, I can use this knowledge, transfer it to Sarooma and thus also guarantee the quality of Sarooma.

Jochen Schaal

Jochen Schaal

Managing Director

From attending many acoustics conferences over the years, I have been able to build an extensive network. Among others, this has led to cooperations with d&b Audiotechnik, the Fraunhofer Institute for Building Physics and the Stuttgart University of Applied Sciences. This is also one of the reasons¸ why Sarooma fits so well with SoundPLAN.

Product Support

My first steps into room acoustics planning 20 years ago were to upgrade the rehearsal rooms of my own and friends’ bands. Since then, acoustics, good sound, has been my passion and profession. My scientific work dealt with the validation of room acoustics prediction methods together with SoundPLAN. At Sarooma, I take care of data maintenance, support industry and planning customers, organize trainings and contribute ideas for the development of the software.

Product Support

Working in different fields of acoustics, I was able to build up a versatile expertise and a good network. When creating content for Sarooma’s social media presence, as well as working on the new Sarooma website, I am able to not only share my expertise, but also put my creative side to work.
