Latest plugs get a grip
August 1st 2005 Push-In earplugs with grip rings integrated into the foam have been developed by Aearo. They are said to afford excellent protection, with an SNR of 34dB and come with or without a cord.
The foam cone can be inserted deep into the ear canal to form a low pressure seal against noise.
The ‘mouldable’ shape,combined with the softness of the EAR form foam helps to provide all-day comfort.
When earplugs slip in the ear, the attenuation level also slips. Aearo has incorporated grip rings into the foam. These help the wearer position the plugs for optimum protection and help to ensure that the fit remains optimal.
No roll-down is required and the company says there is no need for the user to wash their hands as the plug’s no-touch stem eliminates the need to touch the foam tip. Push- Ins are ready to use straight from the pack. More articles from 3M UK Ltd: |
