During this time, several patents have been filed under his co-operation, among others a patent for the method of delta stereophony.
In 1990, he founded the office ADA Acoustic Design Ahnert, initially with only two employees in the old location of the former institute. In January 1993, the office moved to a new location in the Berlin Innovation and Start-Up Center (BIG) in the former industrial area of AEG in the district of Wedding.
