Progress in product sound quality

R.H. Lyon was a pioneer in several areas of acoustics, vibrations and noise control. His development of sound quality as an integral part of noise control engineering and product sound design is just one of many examples of his significant contributions to areas of importance in noise control engineering. In this presentation an overview of the Product Sound Quality workshops he organized in 1997 and 2002 will be given together with a summary of how the field has developed over the last 20 years, due, in no small part, to his leadership. The presentation will conclude with some personal memories of working with him.
