Description

The 3M™ PELTOR™ H540A Optime™ III Earmuff has been developed for effective hearing protection in the most demanding noise environments where noise exposures are expected to reach as high as 105 dBA.

  • Features unique “double-shell” earcup design (two cups connected via foam inner layer) to boost the noise reduction throughout the full range of low and high frequencies
  • Durable stainless steel headband resists bending and warping and distributes weight for a low-pressure fit
  • Lightweight headband works in conjunction with earcup pivot points that tilt to maximize wearer comfort
  • Soft, liquid & foam filled replaceable cushions help the earmuffs fit comfortably against the head to help provide an effective noise-blocking seal
  • High protection level: SLC80-33db, Class 5

Key certifications:

SLC80 33dB

This hearing protection product complies with the Australia/New Zealand standard and has been tested in accordance with AS/NZS 1270.

It has an SLC80 rating of 33 (which in rough terms means it blocks about 33dB of noise) and is a Class 5 hearing protector.

  • Class 1: SLC80 10–13 - Suitable for <90 dB noise levels
  • Class 2: SLC80 14–17 - Suitable for <90-95 dB noise levels
  • Class 3: SLC80 18-21 - Suitable for <95-100 dB noise levels
  • Class 4: SLC80 22-25 - Suitable for <100-105 dB noise levels
  • Class 5: SLC80 ≥26 - Suitable for <105-110 dB noise levels

SLC80 Explained

Under AS/NZS 1270:2002, hearing protection is tested for its Sound Level Conversion (SLC80) rating, which indicates the difference between the environmental noise and the sound reaching the wearer’s ears. This rating helps determine the appropriate Class of hearing protection for specific noise levels.

Australian and New Zealand workplaces are obligated under AS/NZS 1269.3:2005 to:

  • Conduct noise level surveys to assess exposure (measured as LAeq,8h).
  • Provide suitable hearing protection for workers exposed to noise above 85 dB(A).
  • Ensure hearing protection is maintained and properly fitted to achieve effective attenuation.

Employers must select hearing protection suitable for the measured noise levels, ensuring compliance with occupational noise management regulations.

NRR 30

An NRR of 30 means that the hearing protection is estimated to reduce noise levels by an average of 30 decibels across various frequencies.

'NRR' in hearing protection stands for 'Noise Reduction Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the NRR value, the greater the noise reduction level is considered to be.

NRR is primarily used as a rating system in North America, while Europe often uses 'SNR' (Single Number Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.

SNR 34

An SNR of 34 means that the hearing protection is estimated to reduce noise levels by an average of 34 decibels across various frequencies.

'SNR' in hearing protection stands for 'Single Number Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the SNR value, the greater the noise reduction level is considered to be.

SNR is primarily used as a rating system in Europe, while North America often uses 'NRR' (Noise Reduction Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.

Product Care

Cleaning

  • Wipe the ear cups and headband with a soft, damp cloth to remove dirt and oils.
  • Avoid using harsh chemicals, bleach, or submerging the earmuffs in water, as this may damage the materials.
  • Allow the earmuffs to air dry completely before storing or reusing them.

Storage

  • Store the earmuffs in a cool, dry place away from direct sunlight and extreme temperatures.
  • Use the original packaging or a protective case to prevent dust accumulation and physical damage when not in use.
  • Avoid placing heavy objects on top of the earmuffs to maintain their shape and effectiveness.

    Really very useful

    Excellent! I needed it so much since there were frequent false alarms during the mid-night weeks ago. It was caused by the breakdown of the electricity system that affected by the construction site near my home. After putting on this important gadget(Earmuff) for sleeping , those noises from the shocking , horrifying and annoying alarm reduced (at least 50%) and I could then handle the evacuation process calmly. It is so great to have it! Thanks a lot!

    Best Purchase Ever!

    Got these to block out my noisy neighbours and the street noise around my apartment and I could not be happier! They fit well over my earbuds and are comfortable with glasses on as well - I've been wearing them several hours every day and have not had any issues. They muffs are bigger than they look in the pictures though - I was expecting a slimmer design that could potentially be mistaken for a pair of headphones but these are pretty hefty.
