Description

Featuring level-dependent Aware Technology™, ISOtunes LINK Aware is an over-ear hearing protector built to be worn all day long. Communicate with colleagues and listen for warning signals all while enjoying nonstop certified protection.

UNDERSTANDING AWARE TECHNOLOGY™

ISOtunes Aware products are best suited in environments that are not consistently loud. If your environmental noise is above 85dB, the Aware volume will shut off to protect your hearing. When Aware Technology is off, products will block noise passively similarly to a standard earmuff.

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 25

An NRR of 25 means that the hearing protection is estimated to reduce noise levels by an average of 25 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.

Ear muff aware
Only gripe I have is it doesn’t come with a secondary rechargeable battery solution. Also I do feel the headband impression due to being a short trimmed hairstyle if I wear them all day. Phone calls are awesome and Bluetooth works well. Sound suppression is a bonus and the aware function is the best thing about these. It is quite difficult to hear conversation while in a noisy area as the muffs cut the sound due to ambient noise making it easier to hear colleagues when the muffs are switched off. Overall, extreamely satisfied about my purchase and addition to tax time deduction.
Also, I do find them a bit fiddly when hitting the answer phone call button as it is smooth and hard to locate. It should have an impression for easier navigation.
