Acoustics and RF

The purpose of this page is to keep track of my activities within acoustics and RF technology.

The rough division is this: whatever concerns acoustics, speech sciences, and applied mathematics is work-related. All that concern radios (amateur and broadcast) as well as electronics in general is something I do not get paid for doing it.
