Teaching

Teaching activities comprise courses on Fundamental Acoustics and Noise Control, Building Acoustics, Room Acoustics and integrated courses on design methods in Architectural Acoustics with emphasis on co-operation between engineers and architects.

Research

Research activities include theoretical and experimental sound insulation, acoustic modelling techniques, reflection of sound from curved surfaces, diffraction effects of reflectors, development of room acoustic computer models (Odeon), design for acoustic quality in buildings, including sound classification of buildings and new building technology with high sound insulation. Development of measurement methods for reverberation time and scattering from surfaces.

Consultant work

Consultant work comprise the development of a new open telephone box for the City of Copenhagen, the development of new sound absorbing materials, and renovation of the concert hall of the Danish Radio in Copenhagen. From 2001: Renovation of the Alberta Jubilee Auditoria in Calgary and Edmonton, Canada (with Jordan Akustik).
