3M Peltor X4A Over-the-Head Noise-Cancelling Ear Muffs

Low frequency sounds require specialist ear protection, which is expertly provided by the innovating sealing ring and new ear cushion technology of the 3M PELTOR X4A Over-the-Head Noise-Cancelling Ear Muffs. In addition, the ear muffs are dielectric and impact resistant for multi-hazard environments.

Key Information

  • EN 352 - 1
  • SNR (Simplified Noise Reduction): 33dB
  • One universal size
  • Price is per pair of ear muffs

What Are the Key Features of the Over-the-Head Noise Cancelling Ear Muffs?

  • Noise-Reduction: Reduces noise levels up to 33dB for protection
  • Low Frequency Protection: The innovative sealing ring and new ear cushion technology provides fantastic protection against low-frequency noises
  • Electrical resistance: Flat headband is electrically insulated, so earmuffs are 'dielectric'
  • Comfortable: Optimises weight distribution with wide soft ear cushions for maximum comfort
  • Breathable: Twin headband design provides heat dispersion for breathable wear
  • Impact Resistant: ABS plastic cups are rigid and impact resistant, thermoplastic polyurethane outer cup coating protects from abrasions

What Are the Safety Specifications of the 3M Over-the-Head Noise-Cancelling Ear Muffs?

The 3M PELTOR Noise Cancelling Ear Muffs have been tested in accordance with a number of specifications to ensure your safety. They offer particularly protection against low frequency noises, as well as being dielectric or electrically-resistant for additional safety in hazardous environments. The cups of the ear muffs are resistant to knocks, impacts and abrasions.

SNR (Simplified Noise Reduction)

The Ear Defenders achieve an SNR score of 33dB. Further attenuation ratings are as follows:

  • High frequency = 36
  • Medium frequency = 30
  • Low frequency = 22

EN 352 - 1

This standard certifies that the ear muffs have been approved for providing hearing protection as part of protective workwear.

What Are the Uses of the 3M Peltor X4A Over-the-Head Ear Muffs?

The noise cancelling ear muffs are ideal for use in extremely loud environments. Following are some suitable applications:

  • Agricultural
  • Pharmaceutical
  • Utilities
  • Metal processing
  • Automotive
  • Manufacturing
  • Printing
  • Foundry
  • Heavy engineering
  • Mining

How Comfortable Are the 3M PELTOR X4A Ear Muffs?

The twin headband design of the ear muffs will disperse heat, and the stainless steel design offers consistent pressure for a comfortable, breathable fit over 8 hours of wear. The wide soft ear cushions will remain comfortable and evenly distribute weight.

Impact Resistant and Dielectric

The ear muffs are designed for multi-hazard environments, with rigid ABS plastic cups to protect against knocks and impacts. In addition, the ear muffs are electrically resistant thanks to the electrical insulation on the wide, flat headband.

What Is Signal to Noise Ratio (SNR) and Noise Attenuation?

The SNR ratio of ear-protection indicates the amount by which background noise will be reduced, or attenuated. So if you work around machinery with a background noise of 100dB, then ear muffs with an SNR of 32 will reduce the background noise to 68dB, protecting your ears. Ear muffs will reduce the overall background noise by differing amounts depending on whether the noise is medium, low or high frequency.

Sizing of the 3M PELTOR X4A Noise Cancelling Ear Muffs

The ear muffs are available in one size that should suit most users.
