Earplugs or earmuffs?
Selection depends on noise exposure, wearing time, other PPE and communication. Earplugs, headband earmuffs and helmet-mounted protectors have different fitting requirements. Poor fit or discomfort can reduce consistent use.
Understand EN 352 parts
EN 352-1 covers earmuffs, EN 352-2 earplugs and EN 352-3 earmuffs attached to head or face protection. Other parts cover additional functions. EN 352 alone therefore does not describe every property.
Understand attenuation data
SNR and H/M/L data support assessment using exposure information and an appropriate method. They are not universal values to subtract from any noise level. Selection must also consider warning signals and communication; excessive attenuation can interfere with these.
Prepare for use
Send exposure measurements or requirements, tasks, wearing time and helmet or eyewear combinations. Request instructions, attenuation data and compatible accessories. Fitting training and care contribute to real-world performance.
Start with exposure information
Selection needs noise measurements, exposure duration and an understanding of communication and warning signals. Appearance, price or a headline attenuation value alone cannot determine suitability.
