In this episode, the bald guys sit down with Paul Delderfield, a noise and vibration specialist from the UK's Health and Safety Executive. Paul shares how his automotive background led to a fulfilling second career regulating workplace noise, and why hearing loss is one of the most underestimated occupational health risks. The conversation explores the social impacts of noise-induced hearing loss, misconceptions around PPE as a first line of defense and real-world examples of how engineering controls can dramatically reduce risk.
