Salon environments generate noise from multiple sources including hair dryers, clippers, music systems, ventilation equipment, and conversations. When combined, these sources can produce noise levels that exceed occupational safety thresholds and local noise ordinances. OSHA regulates workplace noise exposure to protect employee hearing, while local ordinances govern noise that affects neighboring businesses and residents. Inspectors may evaluate noise levels during OSHA workplace inspections or in response to noise complaints. This guide covers the noise standards applicable to salons, how to measure your noise levels, and how to achieve and maintain compliance.
Noise-induced hearing loss is permanent, progressive, and entirely preventable. Salon professionals face daily exposure to noise levels that, while not immediately painful, can cause measurable hearing damage over months and years of cumulative exposure. The danger is insidious because hearing loss from occupational noise exposure occurs gradually without obvious symptoms until significant damage has occurred.
Hair dryers are the primary noise source in most salons, producing between 80 and 95 decibels depending on the model and speed setting. Stylists who use dryers for multiple hours per day accumulate substantial noise dose. Clippers and trimmers add 70 to 85 decibels. Background music, client conversations, and equipment noise contribute additional decibels that compound the total exposure.
The decibel scale is logarithmic, meaning that a 3-decibel increase represents a doubling of sound energy. A salon with multiple dryers operating simultaneously, background music, and normal conversation can easily reach 90 to 100 decibels in certain areas. At these levels, OSHA standards limit permissible exposure duration significantly.
Beyond employee hearing protection, noise affects client comfort and satisfaction. Excessive noise makes it difficult for clients to communicate with their stylist, creates stress, and degrades the overall salon experience. Clients with hearing aids are particularly sensitive to loud environments.
Noise that travels outside the salon can trigger complaints from neighboring businesses and residents, particularly in mixed-use buildings, shopping centers, and buildings with shared walls. Local noise ordinances set limits on the noise level measured at the property boundary or at the neighbor's location, and violations can result in fines and orders to reduce noise output.
Noise regulations affecting salons come from OSHA workplace safety standards, local noise ordinances, and building codes that address sound transmission between spaces.
OSHA permissible exposure limits set the maximum noise dose an employee may receive during a work shift. The standard permissible exposure limit is 90 decibels averaged over an eight-hour shift. For every 5-decibel increase above 90, the permissible exposure time is halved. At 95 decibels, the limit is four hours; at 100 decibels, two hours. OSHA also requires a hearing conservation program when noise levels reach or exceed 85 decibels averaged over eight hours.
A hearing conservation program includes noise monitoring, audiometric testing for exposed employees, hearing protection availability, training on noise hazards and protection methods, and recordkeeping. While full hearing conservation programs are more commonly associated with manufacturing and construction, busy salons with sustained dryer use can reach the 85-decibel threshold that triggers these requirements.
Local noise ordinances vary significantly but typically set maximum allowable noise levels at the property boundary or at the nearest noise-sensitive receptor. Commercial zones generally allow higher noise levels than residential zones. Time-of-day restrictions may impose lower limits during evening and nighttime hours. Music and amplified sound may have separate, more restrictive limits.
Building code sound transmission requirements specify minimum Sound Transmission Class ratings for walls, floors, and ceilings between different occupancies. These requirements are most relevant during construction or renovation and affect the amount of noise that can travel through building elements to adjacent spaces.

Workplace safety conditions including noise exposure contribute to the comprehensive safety evaluation the MmowW assessment provides. Protecting staff health supports your salon's long-term quality and stability.
Download a sound level meter app on your smartphone for a preliminary assessment. While not as precise as professional equipment, these apps provide a reasonable estimate of noise levels. Measure noise at each workstation during peak activity with dryers running, music playing, and normal conversation occurring. Note areas and times when noise levels seem highest. If your measurements suggest levels approaching or exceeding 85 decibels, consider arranging a professional noise assessment.

Conduct noise measurements at each workstation and common area during typical operating conditions. Measure during both peak and off-peak periods. Record the noise level, the sources contributing to the measurement, and the duration of exposure at each level. If preliminary measurements suggest levels at or above 85 decibels, engage a qualified industrial hygienist for a professional noise assessment.
Step 2: Identify the Loudest Sources
Rank your noise sources by their contribution to overall levels. Hair dryers, music systems, ventilation fans, and clippers are typical primary sources. Note which sources are continuous versus intermittent. Focus noise reduction efforts on the sources that contribute most to overall exposure.
Step 3: Reduce Noise at the Source
Replace older, louder hair dryers with newer models designed for reduced noise output. Many modern professional dryers operate at 75 to 85 decibels, significantly quieter than older models. Maintain equipment regularly, as worn bearings and motors generate increased noise. Set music system volumes to levels that allow normal conversation without shouting.
Step 4: Modify the Environment
Install sound-absorbing materials on walls and ceilings to reduce reflected noise. Acoustic panels, ceiling tiles with high noise reduction coefficients, and soft furnishings absorb sound energy and reduce overall noise levels. Position noisy equipment away from walls to reduce sound reflection.
Step 5: Provide Hearing Protection
Make hearing protection available to staff who are exposed to elevated noise levels. Foam earplugs reduce noise exposure by 15 to 30 decibels and are inexpensive. Custom-molded musician's earplugs reduce noise while maintaining speech intelligibility, which is important for client communication. Train staff on proper earplug insertion and the importance of consistent use.
Step 6: Document and Monitor
Maintain records of noise measurements, equipment purchases, hearing protection availability, and any employee audiometric testing. Monitor noise levels periodically, especially when equipment changes or salon layout modifications occur. Update your noise control measures as needed based on ongoing monitoring.
Yes. Research confirms that sustained exposure to noise at or above 85 decibels can cause permanent hearing damage. Hair dryers commonly produce 80 to 95 decibels, and a busy salon with multiple dryers operating simultaneously can exceed 90 decibels in stylist work areas. Stylists who use dryers for several hours daily accumulate noise exposure that meets or exceeds levels known to cause gradual hearing loss. The damage occurs to the hair cells in the inner ear, which do not regenerate. Early signs include difficulty hearing conversations in noisy environments and tinnitus, a persistent ringing in the ears.
OSHA requires a hearing conservation program when employee noise exposure reaches or exceeds an eight-hour time-weighted average of 85 decibels. Many salon owners assume this threshold only applies to manufacturing or construction environments, but a busy salon with continuous dryer use can reach these levels. The program requirements include noise monitoring, annual audiometric testing for exposed employees, hearing protection provided at no cost, training, and recordkeeping. Even if your noise levels fall below the mandatory threshold, implementing hearing protection practices proactively demonstrates good employment practices and protects your staff from gradual hearing damage.
Address noise complaints promptly and constructively. First, measure your noise output at the property boundary or at the complainant's location to determine whether you exceed local ordinance limits. If you do exceed limits, take immediate steps to reduce noise transmission. This may include reducing music volume, adjusting operating hours for noisy equipment, installing sound-absorbing materials, or adding sound barriers. If your noise levels are within ordinance limits, document your measurements and communicate them to the complainant. In either case, maintain records of the complaint, your measurements, and any corrective actions taken. Cooperating with neighbors and local enforcement demonstrates good faith and may prevent escalation.
