Robert M Unetich, PE

Bob is the founder PSM Consulting LLC.  He is a registered professional engineer and he has worked in consulting for over 40 years.  In 2014, he became an avid pickleball player and was asked to investigate ways that the sound of pickleball might be reduced in level at residences near his winter home in Florida. That work involved careful analysis of work done by acoustics engineers and at methods of reducing the level of annoyance experienced by neighbors of pickleball courts. This led to a study of how pickleball sounds are generated and propagated.

He has now been working in pickleball sound mitigation for over 8 years and he frequently offers advice and formal consulting services to communities, pickleball clubs and those living near pickleball courts and courts being converted to pickleball.
