Consistent and correct use of hearing protection is critical when exposed to high noise levels in any loud environment.
As a rule of thumb, if you need to raise your voice to be heard by someone an arm's length away, the noise level is likely hazardous (typically above 85 decibels), and hearing protection is necessary.
According to experts at the Mayo Clinic, comfort is key to ensuring hearing protection is worn consistently. Earplugs or earmuffs should fit well, be easy to insert and remove, and feel comfortable during extended use.
Earmuffs
There have been quite a few advancements in earmuff technology. Today you can find passive earmuffs and noise-cancelling earmuffs.
If your primary need is noise reduction for loud, consistent noise: A high-NRR (Noise Reduction Rating) passive earmuff is more than sufficient and often less expensive than noise-cancelling earmuffs.
If you need to hear conversations and alarms: Choose an electronic model. These actively let you hear what you need to while protecting against loud noises. However, they don't replace passive earmuffs if you need a very high NRR.
Advanced electronic earplugs and earmuffs are ideal for dynamic tasks involving forklifts or working near automated systems. These devices use allow safe sound levels like conversations or warning signals to pass through while instantly blocking harmful noise spikes. They're particularly valuable for workers who need situational awareness while staying protected.
Earplugs
Disposable earplugs are cost-effective, widely available, and often provide an adequate seal when properly inserted into the ear canal. Modern designs, such as foam earplugs with improved materials, offer enhanced comfort and better noise reduction ratings (NRR). Custom-molded earplugs are tailored to your ear shape, offering superior comfort and protection, which can make a significant difference in consistent use.
In extremely loud environments, such as near heavy machinery, combining earplugs with earmuffs provides maximum noise reduction.
