What do firearms, industrial machinery, and pickleball all have in common? They produce impulse noise — sudden, high-intensity sounds that can cause serious hearing damage and carry major insurance liabilities.

In this episode, we sit down with Dr. Rob Agnew, Technical Director at Liberty Mutual Insurance, to explore the world of impulse noise and risk communication within the field of Industrial Hygiene. From gunshots and industrial machinery to paddle pops, Rob helps break down what makes these sounds so harmful or not — and why communicating their risks is often just as challenging as m...

 Dj and Lauren Fotsch have worked with the likes of  @Apple ,  @Netflix ,  @Samsung , and  @humane . 

We covered a variety of topics from marketing to family life, forensic failure analysis to artificial intelligence. The topic of Ai really stuck with us... why do we fear Ai? Could we think of it as a benevolent "Assistive Intelligence" as opposed to a malevolent "Artificial Intelligence? ...and whats the difference? 

Here's what we came up with... 

Assistive intelligence: AI systems specifically designed to augment human abilities, providing support in tasks like decision...
