In many work environments, whether it’s on a construction site, inside a factory, or deep in a mine, noise is constant. It’s part of the job, part of the process. But over time, that everyday exposure can quietly become a long-term risk. Understanding when noise levels move from acceptable to harmful isn’t always clear in the moment, yet it makes all the difference in protecting workers and maintaining safe operations.
Staying ahead of noise exposure risks means seeing the data as it happens—without disrupting work. The Edge 8 makes that possible with real-time monitoring you can access remotely, helping teams stay productive while staying protected.
Built with four independently configurable virtual dosimeters inside a single device, it can track exposure against multiple standards at once, ideal for worksites where different regulations or roles require different thresholds.
Monitoring doesn’t have to mean standing still. With built-in Bluetooth® connectivity, the Edge 8 syncs effortlessly to the Edge dB mobile app, letting you view and manage data remotely and safely.
Paired with Detection Management Software (DMS), you can configure setups, automate studies, lock settings, and generate reports—all from a single platform that supports your entire team.
The Edge 8 doesn’t just tell you how loud things are. It helps explain what’s behind the numbers.Its 1/1 Octave Band analysis breaks down noise by frequency, making it easier to identify specific sources like machinery, ventilation, or tools.
When a sudden spike occurs, the device can automatically record a short audio clip and lets users add voice notes to explain what was happening at that moment. Instead of sorting through confusing data later, you get useful context right away, saving time and making reports more accurate and meaningful.
Every worksite is different, and so are the rules that govern them. The Edge 8 is built to meet that challenge with precision and flexibility. It comes preprogrammed with OSHA and ACGIH standards, so you’re ready to monitor compliance right out of the box. But when you need more control, it delivers by allowing you to adjust exchange rates, thresholds, and criterion levels to fit your exact needs.
At the same time, its broad measurement range (70 to 140 dB RMS, up to 143 dB Peak) and support for multiple frequency and time weightings ensure that your data isn’t just compliant. It’s accurate and actionable. Whether you’re addressing routine exposure or sudden spikes, you’ll have the information you need to make informed decisions.
The Edge 8 is available in both a Single Dosimeter Full Kit and a 5-Pack Full Kit for rent, ideal for teams with short-term monitoring needs or rotating project sites. Each kit includes essential accessories, with the appropriate single or multi-bay docking station to support fast deployment and streamlined data collection.
Take control of your noise monitoring program with a tool that meets your standards—without compromise.
