Salon environments generate noise from multiple sources including hair dryers, clippers, vacuum systems, background music, client conversations, and mechanical equipment. OSHA establishes permissible noise exposure limits for workers, and local noise ordinances regulate sound levels that affect neighboring properties. While individual salon noise sources may not seem dangerous, the cumulative effect of multiple sources over a full workday can approach or exceed regulatory thresholds. Health and safety inspectors may assess noise levels during workplace inspections, and excessive noise exposure creates liability for hearing damage claims. This guide covers noise level inspection requirements for salon businesses.
Salon owners typically do not consider noise a significant workplace hazard because individual noise events seem moderate. However, studies measuring salon noise levels have documented exposures that can exceed safe thresholds during busy periods. Professional blow dryers can generate noise levels of 85 to 95 decibels at the operator's ear. Clippers produce 70 to 85 decibels. When multiple dryers, clippers, and other equipment operate simultaneously in an enclosed space, the combined noise level increases significantly. Background music played at levels sufficient to be heard over equipment noise adds to the total exposure.
OSHA's permissible exposure limit for occupational noise is 90 decibels averaged over an eight-hour workday using A-weighted measurement. The action level, which triggers hearing conservation program requirements, is 85 decibels averaged over eight hours. At the action level, employers must implement a hearing conservation program that includes noise monitoring, audiometric testing, hearing protectors, training, and record-keeping.
The relationship between noise level and safe exposure duration is not linear. For every five-decibel increase above 90 decibels, the permissible exposure duration is halved. A noise level of 95 decibels is permitted for only four hours, 100 decibels for two hours, and 105 decibels for one hour. A stylist operating a blow dryer at 95 decibels for several hours while also being exposed to ambient salon noise could exceed the permissible exposure limit.
Local noise ordinances establish maximum allowable noise levels at property boundaries. Salons in mixed-use or residential areas may need to manage exterior noise from HVAC equipment, exhaust fans, and interior noise that transmits through walls and windows. Noise complaints from neighbors can trigger inspection and enforcement action.
Client comfort is also affected by noise levels. Excessive noise in the salon creates an unpleasant experience that may drive clients away, interfere with communication between stylists and clients, and create an environment that feels stressful rather than relaxing.
Noise requirements come from OSHA workplace safety standards, local noise ordinances, and building codes.
OSHA noise standards under 29 CFR 1910.95 establish permissible exposure limits and require hearing conservation programs when exposure reaches the action level. The permissible exposure limit is 90 dBA as an eight-hour time-weighted average. The action level requiring a hearing conservation program is 85 dBA as an eight-hour time-weighted average.
Hearing conservation program requirements at the action level include baseline and annual audiometric testing for exposed workers, noise monitoring to identify employees at or above the action level, provision of hearing protectors to exposed employees, employee training on noise hazards and hearing protection, and record-keeping of monitoring data and audiometric results.
Local noise ordinances establish maximum sound levels at property boundaries, typically measured in decibels at the property line or at specified distances from the building. Different limits may apply during daytime and nighttime hours. Commercial zones generally have higher allowable noise levels than residential zones.
Building code requirements may specify minimum sound transmission class ratings for walls between commercial and residential spaces, required sound insulation for mechanical equipment, and noise attenuation requirements for HVAC systems.
Equipment noise standards established by manufacturers provide rated noise levels for professional salon equipment. These ratings can be used to select quieter equipment and to estimate cumulative workplace noise exposure.

Noise management reflects the workplace safety standards that the MmowW assessment evaluates. Salons that control noise exposure protect both staff health and client comfort.
Assess noise levels in your salon during peak operating periods when multiple dryers and other equipment are in use. Use a smartphone sound level meter application for an initial screening. If readings approach or exceed 85 decibels, consider professional noise monitoring. Identify the primary noise sources and consider whether noise reduction measures are needed. Check whether you have received noise complaints from neighboring properties.

Measure noise levels at key locations in the salon during typical and peak operating conditions. Take measurements at stylist stations, the shampoo area, the reception desk, the break room, and near major equipment. Measure both peak noise levels and average levels over representative time periods. Use a calibrated sound level meter or a professional noise survey for accurate results.
Step 2: Identify Primary Noise Sources
Rank noise sources by their contribution to overall exposure. Common high-noise sources in salons include blow dryers, clippers and trimmers, vacuum and extraction systems, HVAC equipment, background music systems, and laundry equipment. Determine which sources are controllable and which are inherent to salon operations.
Step 3: Implement Engineering Controls
Reduce noise at the source and along the transmission path. Select low-noise models when replacing blow dryers and other equipment. Install sound-absorbing materials such as acoustic ceiling tiles, wall panels, and carpet or rubber flooring. Isolate noisy mechanical equipment with vibration dampening mounts. Maintain equipment regularly, as worn bearings and loose components increase noise output.
Step 4: Implement Administrative Controls
Adjust work practices to reduce noise exposure. Stagger the use of blow dryers so that fewer operate simultaneously. Set maximum volume levels for background music systems. Rotate stylists between high-noise and low-noise tasks. Schedule noisy maintenance activities during off-hours when possible.
Step 5: Provide Hearing Protection If Needed
If engineering and administrative controls cannot reduce exposure below the action level, provide hearing protectors to exposed employees. Select comfortable protectors that reduce exposure to safe levels while still allowing communication. Ensure that protectors are properly fitted and that employees are trained on their use and care. Hearing protection should be a last resort after other noise reduction measures have been implemented.
Step 6: Monitor and Document
Establish a schedule for periodic noise monitoring to verify that control measures remain effective. Monitor noise levels when new equipment is introduced or when salon layout changes. Maintain records of noise assessments, control measures implemented, hearing protection provided, and any audiometric testing conducted. Review records annually and update the noise management plan as needed.
Research has shown that noise levels in busy salons can approach or exceed levels associated with hearing damage over prolonged exposure. Individual blow dryers typically produce 85 to 95 decibels at the operator's ear, and multiple dryers operating simultaneously in a confined space can generate combined levels exceeding 90 decibels. The OSHA permissible exposure limit of 90 decibels over eight hours assumes continuous exposure, and salon stylists who spend significant portions of their shift blow-drying may be at risk. The risk is cumulative, meaning damage develops gradually over years of exposure without obvious symptoms until hearing loss becomes significant. Salon owners should not assume that noise is not a concern simply because no one has complained. Noise-induced hearing loss is preventable with proper monitoring, noise reduction measures, and hearing protection when necessary.
You are required to provide audiometric testing if your salon's noise monitoring indicates that any employee's noise exposure equals or exceeds the action level of 85 decibels as an eight-hour time-weighted average. At the action level, OSHA's hearing conservation standard requires baseline audiograms within six months of the first exposure at or above the action level and annual audiograms thereafter. The employer must compare annual audiograms to the baseline to identify significant threshold shifts that indicate hearing deterioration. If a standard threshold shift is identified, the affected employee must be notified, hearing protectors must be refitted or replaced, and a referral for audiological evaluation may be appropriate. Even if your noise levels are below the action level, providing periodic hearing screenings as part of a wellness program demonstrates proactive health management.
Several practical measures can reduce salon noise without major construction. Replace older blow dryers with newer low-noise models, as technology has improved significantly. Install acoustic ceiling tiles, which absorb sound and reduce reverberation. Add soft furnishings such as upholstered seating, fabric window treatments, and area rugs that absorb rather than reflect sound. Place rubber anti-vibration pads under equipment. Set background music at lower volumes and use speakers positioned to distribute sound evenly rather than requiring high volume. Stagger blow-drying schedules so fewer dryers operate simultaneously. Maintain all equipment regularly, as worn bearings, loose housings, and clogged filters increase noise. These measures collectively can reduce ambient noise levels by several decibels, which represents a meaningful reduction in exposure.
