our people

Glenn LeembruggenGlenn Leembruggen is the principal of Acoustic Directions.  Glenn is one of the world’s leading experts in the acoustic design of sound systems for important buildings that have demanding requirements for music and speech amplification.

Glenn’s holistic understanding of the interdependence of architecture, acoustic environment, sound systems and sound quality brings great value to projects.  His approach to acoustic design is unique, combining knowledge of music, high-level acoustic and electrical theory, practical knowledge and measurement skills along with a high listening acuity.

In recognition of his industry work and support of their Audio and Acoustics program, Sydney University has appointed Glenn as an Associate of the Architecture and Design Faculty.
 
His current research areas are measurement and prediction of speech intelligibility, prediction of acoustical absorption and transmission loss, loudspeaker array design and the optimisation of sound in listening rooms.

Glenn has presented papers at international conferences on the prediction of speech intelligibility and the design of innovative loudspeaker solutions for problem spaces.  He has authored a number of journal papers and is a member of the maintenance team for the standard issued by the International Electrotechnical Commission (IEC) relating to the measurement of speech intelligibility by Speech Transmission Index.

For relaxation, Glenn plays saxophone in two performing rock and roll bands.
