Highlights

  • Represents the ultimate in earmuff technology by combining extreme noise protection with exceptional wearer comfort
  • A high visibility option is available for dangerous work environments
  • Patented liquid & foam filled cushions provide a quality noise seal with low pressure for all day wearer comfort
  • Stainless steel headband wires with four point suspension helps distribute cushion pressure evenly & earcups pivot for consistent fit

The H10 Series is a high performance hearing protector and has been developed for use in extremely noisy environments. The protection is based on a technology with a double casing minimising esonance in the casing giving optimum high-frequency attenuation. An acoustic connection between the inner and outer casings provides maximum low-frequency attenuation. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure.

Unique double-shell cup design provides high attenuation for eight-hour TWA noise exposures up to 105 dBA

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.
