Lectures / Noise Exposure and Hearing Conservation
Noise Exposure and Hearing Conservation
Hearing loss is permanent and preventable. This session explains how daily noise exposure is measured and calculated, when hearing protection becomes mandatory, and how to select protectors that reduce noise to a safe level without over-attenuating.

Managing noise exposure and hearing conservation on site.
What you will take away
By the end of this session you will understand the key principles behind health hazards and be able to apply them to your own workplace with confidence. The lecture keeps the theory practical and connects every point back to the relevant EN standards and tools available across SafetyOrbit.
Watch and follow up
Live sessions are announced on the Training Calendar, and recordings are added to the Lectures library afterwards. To go deeper on the standards referenced here, visit the EN Standards Library.
Daily exposure combines measured noise level with time spent in it.
Frequently asked questions
How is daily noise exposure measured?
It is calculated from the measured noise level and the duration of exposure to it, combined into a single daily personal exposure value that can be compared against action and limit values.
At what point does hearing protection become mandatory?
Once daily exposure reaches the lower or upper exposure action values set in workplace noise regulations, protection must be made available and then made mandatory as exposure rises further toward the limit value.
Can hearing protection provide too much attenuation?
Yes – over-protecting can isolate a worker from alarms, warnings and colleagues, so protectors should be matched to actual measured exposure rather than always maximised.
Is hearing loss from noise exposure reversible?
No, noise-induced hearing loss is permanent, which is why prevention through exposure control and correctly selected protection matters more than any after-the-fact remedy.
Where can I watch this lecture?
Live sessions appear on the Training Calendar, with recordings added to the Lectures library afterwards.
