Workplace noise is one of the most common hazards in the industry today, yet its real-world impact is staggering. According to the World Health Organization (WHO), over 5% of the world’s population—or 430 million people, including 34 million children—require rehabilitation to address disabling hearing loss.
Protecting people from this massive, invisible threat is not just a regulatory box to tick; it is an essential, must-have skill for any ambitious Health and Safety professional.
This July, Gradi Health & Safety Limited is hosting our next premier training course: OHTA 503 – Noise: Measurement and Its Effects.
Why This Course Matters
We understand that the science of sound and acoustics can seem intimidating at first. That is why our expert instructors break it down into simple, highly practical steps.
Whether you are building your occupational hygiene foundation from scratch or updating your technical skills to stay sharp in the field, this course gives you the confidence you need. Instead of just guessing if a workplace is too loud, you will leave this course knowing exactly how to prove it, measure it, and fix it.
(Plus, completing this course is an excellent way to earn your required Continuing Professional Development (CPD) points!)
