The effectiveness of your Cotral Lab ear plugs

An effective attenuation is based on four key pillars:

Hearing protector compliance

A customized hearing protector is comprised of an earplug and an acoustic filter. The standard requires the compliance of both in combination. Cotral Lab's plug and seven different filters are fully compliant with Standards AS/NZS 1269.3:2005 requirements.

Ear mold quality control before manufacturing the best custom ear plugs

The first step in manufacturing your device is the ear impession or mold. A high-quality ear mold is the key to having an exceptional custom ear plug.

This is why each Hearing Protection Specialist at Cotral Lab:

  • Follows a specific protocol
  • Receives continuing training of the highest standard of the British Society of Audiology (BSA)
