Please note most ear plugs are available corded and uncorded in a variety of individual packs.
Classic, easy, and effective protection.
Inserts easily and molds to the ear canal for extra comfort. No roll-down needed.
Reduce waste with durable, easy-to-use ear plugs that are premolded for your comfort.
Developed for food processing and other industries where it is critical to keep ear plugs from contaminating products and processes. Implanted stainless steel ball bearing is encased in each earplug.
A comfortable, effective, lightweight alternative to ear muffs. (Please note: Banded hearing protectors can be worn in various positions or with different protection tips which may affect the NRR or CSA class.)
The 3M™ E-A-R™ One Touch Dispenser delivers ear plugs to workers on the move with each turn. Reusable and free-standing, the base can be re-stocked with One Touch refills of your choice: Classic, SuperFit, E-A-Rsoft, and more. The versatile design includes tabletop or wall-mount options so that grabbing ear protection on the go is as easy as it should be.
Hearing Protection Devices (HPDs) are selected based on the noise exposure at the workplace. Other important considerations are comfort, fit, ability to communicate, compatibility with other personal protective equipment and the workplace environment. The following methods can be used to select the most appropriate HPD: Noise Reduction Rating (NRR), CSA Class, Octave Band or Fit Testing.
The NRR is a single number method that describes the overall sound level reduction across frequencies (attenuation) of a HPD in decibels (dB) based on a laboratory test. Since the NRR is a laboratory test it is recognized that it may overestimate the protection achieved by users in their workplace settings. Therefore, it is recommended that the NRR be derated in order to better estimate workplace protection. The NRR derating scheme can be found in CSA Z94.2-14 Hearing Protection Devices Standards, Table 2: Effective rating calculations for the NRR.
The CSA Class describes the sound level reduction (attenuation) of a HPD using the letters A, B, or C which pre-assigns the HPD according to defined attenuation ranges. The CSA Class can be found in CSA Z94.2-14 Hearing Protection Devices Standards, Table 3: Assignment of class based on the octave band attenuation values measured according to ANSI S3.19. It is important to note that the Class pertains only to level of attenuation of the HPD, not to any of its other characteristics.
