NOISE

OVERVIEW

Our Noise Monitoring Series combines the power of the NM20 (Noise Sensor) and the NM60 (Noise Hub) to provide a scalable, real-time noise monitoring and alerting system for industrial, manufacturing, and high-noise work environments.

This integrated system is ideal for large-scale noise management, allowing real-time monitoring, proactive hearing protection enforcement, and seamless expansion as operational needs grow.

INDUSTRY APPLICATION

NM60

CENTRAL MONITORING HUB

The NM60 acts as the primary tracking point of all connected NM20 sensors, processing real-time noise levels from the connected NM20 sensors into visual alerts.

OVERVIEW

The NM60 functions as a central noise monitoring hub that aggregates real-time data from up to 10 x NM20 Sensors simultaneously via wireless communication (up to 100 meters per sensor), providing a central visual warning point for employees before they enter high-noise zones, such as workshops, plants, or large production areas.

Central Noise Tracking & Display:
- Primary point for real-time noise level tracking, reporting, and system-wide awareness from all connected NM20 sensors.
- Positioned at access points of large areas to warn employees of high noise levels before they enter.
