Overview
The EDGE Personal Noise Dosimeter is a compact, wearable occupational noise monitoring instrument engineered for high-fidelity, real-time assessment of time-weighted average (TWA) noise exposure in accordance with OSHA, NIOSH, and EU Directive 2003/10/EC requirements. Utilizing a 1/4-inch pre-polarized electret condenser microphone mounted directly on the shoulder—positioned near the ear reference point—the EDGE implements true RMS detection with selectable A- or C-weighting, fast/slow integration, and peak capture up to 143 dB. Its measurement architecture complies fully with ANSI S1.25-1991 (R2021) and IEC 61252:2017 standards for personal sound exposure meters, ensuring metrological traceability and regulatory acceptability in GLP-compliant industrial hygiene programs.
Key Features
- Ultra-compact form factor: 3.5″ × 2.1″ × 0.75″ (89 × 53 × 19 mm), weighing only 85 g (3 oz)—designed ergonomically to conform to shoulder contour without impeding worker mobility or comfort.
- Intrinsically safe certification: Certified to UL 913, CSA C22.2 No. 157, MSHA 30 CFR Part 18, AS/NZS 60079-0 & 60079-11, and ATEX II 2G Ex ib IIB T4 Gb (pending final approval), enabling deployment in hazardous locations including oil & gas, mining, and chemical processing facilities.
- Dual-channel data logging: Records LAvg, LEq, LMax, LMin, Peak, LC-AF, exposure duration, and runtime at user-defined intervals (e.g., per-minute sampling).
- Configurable dose parameters: Independent threshold (70–140 dB), exchange rate (3 dB, 4 dB, or 5 dB), and criterion level (70–140 dB in 1 dB steps) support global regulatory frameworks including OSHA 1910.95, ISO 1999, and EU Physical Agents (Noise) Directive.
- Rechargeable lithium-polymer battery: Delivers ≥60 hours of continuous operation per charge; managed via EdgeDock cradle with simultaneous charging and data transfer capability.
- Intuitive 4-button interface and multi-parameter OLED display: Shows SPL, MAX/MIN, Leq/Lavg, LC-AF, Peak, elapsed exposure time, memory status, battery level, and overload indication—all without requiring external software during field use.
Sample Compatibility & Compliance
The EDGE is designed exclusively for human-worn personal noise exposure assessment. Its fixed windscreen and robust IP65-rated enclosure ensure reliable operation under demanding environmental conditions—including dust ingress resistance and protection against low-pressure water jets. It meets the physical and electroacoustic requirements of ANSI S1.25-1991 (R2021) Class 2 and IEC 61252:2017 for personal sound exposure meters. All calibration routines are traceable to NIST standards via compatible acoustic calibrators (e.g., 711-type coupler). The device supports audit-ready data export compliant with FDA 21 CFR Part 11 when used with QSP II software configured for electronic signatures and audit trails.
Software & Data Management
Data acquisition and analysis are performed using QSP II software—a validated, Windows-based platform supporting multi-language UI (English, German, French, Spanish, Italian, Portuguese). QSP II enables batch configuration of multiple EDGE units, automated report generation (PDF/CSV), dose trend visualization, and compliance gap analysis against configurable exposure limits. Raw logged data includes timestamped LAeq,T, instantaneous SPL, and event-triggered peak events. The software enforces role-based access control, full audit trail logging, and secure encrypted storage—facilitating adherence to ISO/IEC 17025 and GxP-aligned quality management systems.
Applications
- Occupational health surveillance in manufacturing, construction, transportation, and utilities sectors.
- Noise mapping and task-based exposure profiling for hearing conservation program (HCP) development.
- Regulatory compliance verification for OSHA PEL/Action Level assessments and EU workplace noise risk evaluations.
- Hazardous area monitoring where intrinsic safety is mandated—e.g., refinery maintenance crews, offshore platforms, underground mining operations.
- Academic and industrial research requiring high-temporal-resolution personal dosimetry with minimal wearer burden.
FAQ
What certifications does the EDGE hold for hazardous area use?
The EDGE carries UL 913, CSA C22.2 No. 157, MSHA 30 CFR Part 18, AS/NZS 60079-0 & 60079-11, and ATEX II 2G Ex ib IIB T4 Gb (under final review) certifications.
How is calibration verified and maintained?
Calibration is performed using a 711-type acoustic coupler traceable to NIST; QSP II software logs all calibration events with operator ID, date/time, and deviation values.
Can the EDGE operate without the EdgeDock cradle?
Yes—the device functions autonomously for up to 60 hours; the EdgeDock is required only for charging and data download.
Is the microphone replaceable in the field?
Yes—the 1/4-inch pre-polarized electret condenser microphone is user-replaceable without tools or recalibration.
Does the EDGE support real-time wireless transmission?
No—it stores data internally and transfers via wired SIR interface through the EdgeDock; no Bluetooth or Wi-Fi functionality is implemented to preserve intrinsic safety integrity.
