Description

The right earplug should feel comfortable in the ear canal without compromising protection. With over 30 years of expertise in advanced earplug development, Howard Leight®energises its unique Bilsom 300 series single-use earplug for a new experience of in-ear fit and increased comfort that your employees deserve. Bilsom® 304’s unique foam formulation delivers both in-ear comfort and visibility with the introduction of the Leight Stripe, a skilled blend of yellow and white polyurethane foam that feels softer in both your hand and in your ear, but does not feel too tight in your ear canal. It is easier to roll-down, and once inserted properly, resists the tendency to back out of the ear canal - ensuring a tight seal for optimal protection. Its smooth, soil-resistant skin prevents the build-up of dirt on the earplug, promoting proper hygiene. Plus, its distinct yellow end is highly visible outside the ear canal for compliance checks!

FEATURES

  • New yellow and white Leight Stripe delivers high degree of comfort and visibility when worn
  • Patented polyurethane foam expands gently in the ear canal, reduces tendency to back out of the ear canal
  • Less expansion pressure creates a more comfortable seal, wears more comfortably than other foam earplugs over long periods of time
  • Smooth, soil-resistant skin prevents dirt build-up, promote proper hygiene
  • Tapered bullet-shape design easier to roll-down and insert, adapts more evenly to shape of the ear canal
  • SLC80 24dB (Class 4) - ideal for medium/high noise environments
  • Comes with 100 pairs
  • Corded
  • Large sized ear plugs
Key certifications:

SLC80 24dB

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 24 (which in rough terms means it blocks about 24dB 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 29

An NRR of 29 means that the hearing protection is estimated to reduce noise levels by an average of 29 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 33

An SNR of 33 means that the hearing protection is estimated to reduce noise levels by an average of 33 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.
