Best Custom hearing protectors 3D scanning process

A comfortable, molded earplug

The manufacturing process for a custom earplug is done in these comprehensive steps:

  • For each employee, impressions of both ear canals are taken
  • 3D printing is used to manufacture a set of custom earplugs based on the impressions

This comprehensive process ensures that both hearing protectors fit perfectly, with 100-micron precision (the width of a strand of hair). They are so comfortable that they can be worn all day.

Protected, but not isolated.

The hearing protection device is personalized for each employee.

SAPAN®, in compliance with OSHA 29 CFR, considers the noise level, level of perception, and the unique traits of each employee to select the right hearing protector.

Qeos offers two ranges of filters, each providing a different level of attenuation.

Your employees' working conditions change; their hearing protection devices should evolve as well!

Is your employee transitioning into a different position? Perhaps working with a new, quieter machine?

Use SAPAN® and, if necessary, change the ear protectors' filters, using the Filter Box. It takes less than two minutes!

Opt for:

  • Safety and convenience: Your employees are always protected, as filters can be changed in-situ. It's easy and fast.
  • Timeliness: Employees can change their filters whenever necessary, on their own.
