Hearing Protection Detection
Detects whether ear defenders or plugs are worn inside designated high-noise zones, and logs how long each person spends in those zones.

Hearing protection detection in designated noise zones
What it detects
Harvested from the computer-vision use-case columns of the Q3 industry papers. Every item below is a rule you can switch on, tune per zone and report on.
Earmuffs and earplugs
Flags people inside a noise zone with no visible hearing protection in place.
Press, stamping and machining areas
Applies the rule where the Q3 papers name noise exposure directly — presses, welding, machining and test cells.
Compressor and pump houses
Covers rotating-equipment rooms and process units where sustained noise exposure is the reason the zone exists.
Time in high-noise areas
Logs dwell per person and per zone, so exposure duration is measurable rather than estimated.
Combined zone PPE rules
Correlates hearing protection with helmet and eye protection where the area requires the full set.
Contractors and visitors
Surfaces non-permanent personnel entering a noise zone without the protection issued at induction.
Noise-zone boundary crossings
Detects the crossing itself, so the event is flagged at the threshold rather than after the fact.
Correlation with noise sensors
Lines up detections with noise, temperature and air-quality readings where that sensor data is available.
Where it applies
The sub-sectors below are the ones the Q3 industry papers name for this detection. Each links to the industry hub.
In Oil & Gas
Required in high-noise zones around drilling operations. Compressor and pump houses on offshore platforms. Refinery process units with elevated noise exposure.
How it works
01
Runs on the cameras you already have
Inference happens at the edge on your existing CCTV and IP streams. No new camera estate, no video leaving site, no cloud round-trip in the detection loop.
02
Thresholds and zones you configure
Draw the zone, set the rule, set the dwell, count and confidence thresholds. Rules differ by area, shift and task, because sites do.
03
Evidence, not just alerts
Every event is logged with camera, zone, timestamp and a clip, so the record is reviewable afterwards and usable in a corrective action.
04
Integrates with what you already run
Events push into your VMS, alerting and reporting stack through Fogsphere Manager, with dashboards broken down by area, shift and crew.
Risk & control objective
Noise-induced hearing loss is cumulative and silent, which makes it one of the few occupational exposures where the record matters as much as the moment. Occupational health and safety management systems require the employer to identify the hazard, define the control and show that it operates — and hearing protection zones are the clearest case of a control that is either worn or not.
What the operator is managing is exposure over time, not a single violation. Detection gives two numbers that were previously unavailable together: how often protection is missing, and how long people actually spend inside the zone. Those two figures drive rotation planning, zone boundaries and engineering-control priorities far better than a periodic dosimetry sample.
