Adrian,

Thank you for the warm wishes. I am quite looking forward to the next 30 years. The past 30 years has certainly been both fun and exciting. Fredk was commenting in a different thread that it must have been an exciting time during the 80s when I was a part of all the ground breaking research going on at the NRC; and it really was. Prior to that research it was generally accepted that sound was perceived differently by each person and they had to search out the speaker that suited their individual taste (some of you may remember the days of the east coast sound, the west coast sound, etc). However, it became apparent early on that this was not the case and that when the visual cues were removed the personal differences also went away. This opened the door to the development of a set of measurements that could be consistently relied on to produce proper sound while at the same time allowed us to identify and discard the ones that did not impact performance. The shear size of this plate of measurements means that after 30 years of pursuing the goal we are still working to this end today; and there is no doubt lots left to do.

Thanks,
