SoundEar® 4-4XL

Rugged, High-Precision Noise Monitoring Built for Heavy Industry.


*When ordering in bulk, please contact us for bulk pricing.


The SoundEar® 4 XL is a ruggedised, high-precision noise monitoring system built for the most demanding industrial settings. A high-strength aluminium core, shock-absorbing rubber bumper and shockproof acrylic front panel handle the knocks that come with a working production floor. The visual alert tells staff when hearing protection is required, and the integrated dosimeter tracks what they were actually exposed to across the shift.


IMPORTANT: Cloud and Modbus integration requires additional configuration. We will need to touch base with you to go through the finer details of your requirements.

    • 🔴 RED – warning: noise level has exceeded the configured safe threshold

    • 🟡 YELLOW – caution: noise levels are approaching the preset limit

    • 🟢 GREEN – safe: sound levels are within the acceptable range and actively monitored

    • 🔢 Live dB readout on the front panel alongside the colour signal

  • For use in:
    • Large factories, workshops and industrial settings

    • Plant and facilities with varying noise levels or intermittent noise
