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.
