This website is dedicated to the solution of acoustical problems. And to the propagation of theory and good practice in the acoustical field.

The site is created and maintained by Jan Voetmann, an acoustical consultant with  more than 40 years of experience in the design of room acoustics and in the interaction between room acoustics and sound systems.

My work over the years has been for theatres, cinemas, concert halls, multipurpose halls, sound studios, control rooms, broad cast facilities etc.
