What it is
What a warehouse noise survey assesses
A warehouse noise survey is an occupational assessment of the noise exposure received by employees working inside warehouse and logistics operations. It focuses on workers — not on the noise emitted from the site to neighbours — and is delivered under the Control of Noise at Work Regulations 2005.
Warehouses combine slow, steady noise (HVAC, conveyors, refrigeration) with short, intense events (pallet drops, reversing alarms, vehicle movements, impact loading) inside large reverberant spaces. The survey is designed to characterise both, and to attribute exposure correctly to the workers actually affected.
The survey is distinct from community vehicle-noise studies or boundary-noise assessment. For wider service context see workplace noise surveys and our workplace noise monitoring page.

- HGV and trailer movements at loading bays
- Reversing alarms and vehicle horns
- Pallet drops and impact loading
- Strapping and shrink-wrap machines
- Conveyor systems and rollers
- Sortation and automated handling lines
- Automated storage and retrieval systems
- Refrigeration units and chillers
- HVAC and roof-mounted fans
- Air-curtain heaters at bay doors
- Compressors and air-line discharge
- Maintenance and cleaning tasks
- Tannoy, alarms and PA systems
- Cardboard balers and waste compactors
When you need a survey
When warehouse noise monitoring is required
- Workers wear hearing protection in some warehouse areas
- Difficulty hearing reversing alarms or PA systems
- New conveyors, sorters or automation installed
- Site layout has been reconfigured
- Increased volumes or new shift patterns
- Hearing concerns reported by workers
- Outdated or missing noise risk assessment
- Frequent loading-bay impact noise
- Customer or contract H&S requirement
- HSE inspection or internal audit
Vehicles & forklifts
Vehicle and forklift noise
Mobile equipment is one of the dominant exposure sources for warehouse workers, particularly forklift and HGV operators.
- Internal combustion forklifts
- Electric forklifts and reach trucks
- Powered pallet trucks
- Tugs and tow trains
- Yard shunters and trailer movements
- HGV manoeuvring at bays
- Cab interior noise for drivers
- Hydraulic mast operation
- Tyres on warehouse flooring
Loading bays
Loading-bay and material-impact noise
Loading bays concentrate many exposure sources at once — vehicle movements, alarms, dock-leveller operation and impact noise from material handling.
- Pallet drops onto bay flooring
- Roller-shutter and dock-leveller operation
- Strapping and crashing of metal banding
- Cage and roll-cage handling
- Steel-on-concrete impact
- Cross-dock activity
- Trailer floor reverberation
- Air-curtain noise at open doors
Reversing alarms
Reversing alarms and warning systems
Audible warning systems contribute both to exposure and to site safety. Hearing protection has to attenuate without removing the worker's ability to hear them.
- Tonal reversing alarms
- Broadband (white-noise) reversing alarms
- Vehicle horns and proximity warnings
- Pedestrian alert systems
- PA and tannoy announcements
- Fire and evacuation alarms
- Equipment fault buzzers
- Audibility against background noise
Conveyors & automation
Conveyors and automated systems
Automated lines often produce moderate but continuous noise punctuated by short transition events at merges, diverts and sorters.
- Roller and belt conveyors
- Slat and chain conveyors
- Merge and divert points
- Sorters and tilt-trays
- Cross-belt sorters
- Automated guided vehicles
- AS/RS cranes and shuttles
- Robotic pick stations
- Drive motors and gearboxes
Mobile worker exposure
Mobile worker exposure
Pickers, drivers and supervisors are rarely exposed to a single environment for any length of time. Their exposure is built up from many short periods in different conditions.
- Forklift and reach-truck drivers
- Order pickers across multiple aisles
- Goods-in and goods-out staff
- Yard marshals and bay staff
- Cross-dock operatives
- Supervisors and team leaders
- Engineering and maintenance staff
- Cleaning and waste-handling staff
Area vs personal
Area readings versus personal exposure
Area readings characterise the warehouse environment; personal exposure characterises individual workers. Both are useful, neither is a substitute for the other.
- Area readings for fixed workstations
- Area readings for hearing-protection-zone definition
- Personal exposure for mobile workers
- Personal exposure across similar groups
- Comparison of static and mobile values
- Cross-check of dosimetry with area data
Personal dosimetry
Personal dosimetry in warehouses
Background on dosimetry method is on the personal noise dosimetry page.
- Shoulder-worn dosimeters on representative workers
- Coverage of full representative shift
- Sampling across each similar exposure group
- Mobile activity captured naturally
- Loading and unloading covered as part of shift
- Calibration before and after deployment
- Notes correlating peak events with observed tasks
Shift & demand
Shift and peak-demand variation
Logistics demand varies hour-to-hour, day-to-day and season-to-season. The survey is planned around the periods that actually drive exposure.
- Day, evening, twilight and night shifts
- Goods-in versus goods-out peaks
- Seasonal volume peaks
- Promotion and event-driven spikes
- Weekend and overtime working
- Reduced staffing periods
Reverberation
Large-space reverberation
Tall, hard-surfaced warehouses sustain sound for longer than smaller spaces, raising background levels and reducing speech intelligibility.
- Tall hard-surfaced internal volumes
- Concrete floors and steel decking
- Limited absorptive surfaces
- Background noise build-up across the shift
- Reduced speech intelligibility
- Degraded alarm audibility
Communication
Communication and alarm audibility
Hearing protection must attenuate noise without preventing workers from hearing safety-critical signals or normal communication.
- Background-to-signal ratio for alarms
- PA and tannoy intelligibility
- Forklift and pedestrian warning audibility
- Risk of over-attenuation
- Suitability of protectors for mobile workers
- Need for level-dependent protectors in some roles
Noise mapping
Warehouse noise mapping
A workplace noise map can support zone boundaries and contractor briefings, but is not a substitute for personal exposure assessment.
- Identification of higher-noise zones
- Support for hearing-protection-zone signage
- Visualisation for contractors and visitors
- Source contribution review
- Comparison before and after controls
- Records to review after layout change
Hearing protection
Hearing protection suitability
Detailed product-level review is delivered through hearing protection assessment.
- Matching attenuation to measured exposure
- Avoiding over-protection that masks alarms
- Compatibility with hi-vis, hats and eyewear
- Level-dependent protectors for mobile workers
- Defined hearing-protection zones
- Training, fitting and supervision

FAQ
Warehouse noise survey FAQs
What does a warehouse noise survey cover?+
A warehouse noise survey is an occupational assessment of the noise warehouse and logistics employees are exposed to during normal operations. It covers vehicle and forklift movements, loading and unloading, reversing alarms and warning systems, conveyors and automated handling, picking and packing activity, and warehouse maintenance. The survey combines area measurements, personal dosimetry on mobile workers and task-based measurements where specific activities dominate exposure.
Is warehouse noise really high enough to need a survey?+
Steady-state noise in many warehouses is moderate, but exposure can still approach or exceed the lower exposure action value (80 dB(A) LEX,8h) once forklift movements, reversing alarms, impact noise from material handling, conveyors, automated systems and large reverberant spaces are taken together. Peak sound pressure from dropped pallets or impact loading can also exceed action values. The survey identifies whether action values are reached, where, and for whom.
Does this page cover community vehicle-noise complaints?+
No. This service concerns employee occupational exposure inside warehouse and logistics operations under the Control of Noise at Work Regulations 2005. It is not a community or residential nuisance survey, environmental noise impact assessment or boundary-noise study for planning purposes.
How is exposure assessed for forklift drivers who move across the site?+
Forklift drivers and other mobile warehouse workers are typically covered by personal noise dosimetry over a representative shift, supplemented by task-based measurements during loading, unloading, picking and maintenance activities. The combination captures both the steady noise of driving and the short, higher-noise events that punctuate a typical day.
Should reversing alarms be measured?+
Yes. Reversing alarms, vehicle horns and audible safety devices contribute to total exposure for workers in their vicinity and influence overall warehouse soundscape. Their levels, frequency content and audibility are reviewed both as exposure sources and as safety-critical communication signals.
Can the survey help with noise-mapping the warehouse?+
Yes, where useful. Warehouse noise mapping can illustrate where steady-state noise is highest, support hearing-protection-zone boundaries and inform contractor or visitor briefings. A noise map complements but does not replace personal exposure assessment.
What about communication and alarm audibility?+
Reverberant warehouses can degrade speech intelligibility and mask safety-critical alarms. The survey can include observations on background noise levels relative to communication needs and alarm audibility, supporting hearing protection that does not over-attenuate at the expense of safety.
Will it cover automated and conveyor systems?+
Yes. Conveyors, sorters, automated guided vehicles and automated storage and retrieval systems are increasingly common in modern warehousing. Their steady operating noise, transition points and maintenance access are all assessed where workers are exposed.
How is shift and seasonal variation handled?+
Warehouses commonly run different patterns across day, evening and night shifts, with peak periods around seasonal demand. The survey is scoped so measurements either represent peak activity or, where this is not possible, the report makes clear how exposure may vary outside the measured period.
Are area readings enough, or do you need personal dosimetry?+
Area readings alone usually under-represent exposure for mobile workers because they cannot follow a worker through their varied tasks. Personal dosimetry is the primary tool for forklift drivers, pickers and supervisors; area readings are useful for fixed workstations and to characterise the warehouse environment as a whole.
Can the survey recommend acoustic treatment for large reverberant spaces?+
Yes — where reverberation is contributing to exposure or to alarm and communication problems, the report can identify candidate areas for acoustic treatment, including suspended absorbers or surface treatment. Detailed acoustic specification work is delivered through our workplace acoustic surveys service.
How often should a warehouse noise survey be repeated?+
Warehouse operations change frequently — new vehicles, layout changes, conveyor extensions, automation upgrades and changed product mix can all alter exposure. A focused review after material changes, or routine review every three to five years, keeps the noise risk assessment and hearing protection arrangements current.
