After Christian Simmons has worked for 25 years building up the database with sound data for more than 1300 construction products, it is now time to hand over to Klas and Erik, who will intensify the work in the future. Christian will remain as technical support to Sonusoft in 2023 and 2024, to facilitate a smooth transition.
Advertising products in the database is a quick and effective way to reach out to and support acoustic consultants in Sweden, Norway, Finland, Denmark, exactly where & when they operate.
Using quality reviewed input data relieves consultants from the tedious task of checking all products before carrying out a calculation. Subscription to those databases means a substantial increase of efficiacy at work.

Christian would like to thank you for a long and pleasant collaboration with advertisers as well as subscribers!
Klas and Erik look forward to continuing to work with you in the future!
