3M™ PELTOR™ MT13H221P3E PROTAC™ III BLACK EARMUFF.

What it is and why choose it

The 3M™ PELTOR™ MT13H221P3E ProTac™ III Black Earmuff is a helmet-mounted electronic hearing protector designed for work in high-noise environments where it is still important to hear surrounding sounds. Its level-dependent ambient listening function helps protect against harmful noise while allowing you to hear warning signals, approaching vehicles and machine sounds up to 82 dB. With high attenuation, automatic power-off and the option to connect external audio devices, it is a robust solution for industrial, construction and railway applications.

Main features

• Helmet-mounted electronic earmuff version (P3E attachment), black.
• Noise-attenuating hearing protector with level-dependent ambient listening.

Applications and use cases

The 3M™ PELTOR™ ProTac™ III MT13H221P3E earmuff is intended for work in noisy environments where communication and awareness of surroundings are important. Typical applications include:

• Industrial areas with continuous or intermittent high noise levels.
• Construction sites.
• Railway work and trackside operations.
• Other noisy workplaces where ambient sounds such as alarms, warning signals, vehicles and machine processes must be heard.

The level-dependent ambient listening function helps users maintain situational awareness while the high-attenuation design provides effective hearing protection.
