A sound level meter measures noise at a specific moment or location. A noise dosimeter measures personal exposure over time, which is what regulations require.
A noise dosimeter is a small wearable device that measures a worker’s total noise exposure over a full shift. It calculates dose automatically based on both noise level and exposure time, eliminating the need for manual calculations or assumptions.
Using only spot measurements requires estimating time and exposure, while a dosimeter:
In short: dosimeters give you answers, not estimates
If your employees are exposed to high noise levels throughout the day, a dosimeter is the most accurate and efficient way to determine compliance and protect against hearing loss risk.
Spartan is designed for fast, large-scale deployment:
Modern wearable noise dosimeters should support fast deployment and multi-device setup to ensure consistent data across teams. This is especially valuable when monitoring across multiple workers or shifts.
No.
With Spartan:
All core tasks—setup, monitoring, and reporting—can be completed from a mobile device without traditional docking workflows.
This eliminates one of the biggest frustrations with older dosimeters.
Spartan Noise Dosimeters support major occupational noise standards, including:
You can measure and report according to multiple standards simultaneously, ensuring compliance across different requirements.
Spartan reports key occupational noise metrics, including:
It can also include:
These metrics help you understand both exposure levels and root causes of noise.
Spartan is designed to deliver reliable, defensible measurements:
Features like audio and motion detection help confirm that measurements reflect real working conditions and haven’t been tampered with.
This is critical for audits, compliance reporting, and internal validation.
Data access is immediate and streamlined:
Spartan enables on-the-spot reporting, reducing delays and manual data handling.
While all basic measurement functions from setup to reporting can be done from your Bluetooth-connected mobile device, G4 LD Utility Software, included with your dosimeter purchase, that broadens post-measurement analysis options. G4 automatically download data from all nearby devices and allows “what-if” analysis by allowing you to modify results to “try out” potential noise control methods, while preserving the original data for compliance purposes. In addition, data easily exports to Microsoft Excel for further analysis.
What G4 LD Software enables:
Because your needs are unique our team will contact you to listen to your specific situation and help customize the right solution for you.
You don’t have to purchase.
Short- and long-term rental options are available, allowing you to:
Rental flexibility is a recommended consideration when selecting a dosimetry solution.
Yes.
An intrinsically safe noise dosimeter (Model 730IS) is available for use in environments like:
This version includes certifications such as ATEX, MSHA, and IECEx.
