Salons are noisy workplaces. A single professional blow dryer produces 80 to 90 decibels, and during peak hours, multiple dryers operating simultaneously combined with background music, conversation, and equipment noise can push ambient levels above 90 decibels. At these levels, the National Institute for Occupational Safety and Health recommends hearing protection because sustained exposure causes irreversible noise-induced hearing loss. Salon professionals who work in these conditions for years develop gradual hearing damage that they attribute to aging rather than to occupational exposure. Noise exposure management training teaches staff to recognize hazardous noise levels, reduce noise at the source, and protect their hearing throughout their careers.
Noise-induced hearing loss develops so gradually that most people do not notice it until significant damage has occurred. The initial damage affects the ability to hear high-frequency sounds, which means that early hearing loss is masked in normal conversation because most speech occurs at lower frequencies. A stylist may work for years with progressive hearing damage, compensating unconsciously by turning up the volume on devices and asking people to repeat themselves, before recognizing that hearing loss has occurred.
The damage is caused by the destruction of hair cells in the inner ear that convert sound vibrations into nerve signals. These cells do not regenerate. Once destroyed, the hearing loss they cause is permanent and irreversible. No medical treatment, hearing aid, or surgical procedure can restore hearing lost to noise damage. Hearing aids amplify remaining sound but cannot replace the clarity of natural hearing.
In salons, the noise hazard is compounded by duration. NIOSH recommends that unprotected exposure to 85 decibels be limited to eight hours. For every three-decibel increase above 85, the safe exposure time is halved. At 88 decibels, the safe exposure time is four hours. At 91 decibels, it is two hours. A salon with multiple blow dryers operating simultaneously can exceed these levels during peak periods that last several hours every day.
OSHA's occupational noise exposure standard at 29 CFR 1910.95 requires employers to implement a hearing conservation program when employee noise exposure equals or exceeds an eight-hour time-weighted average of 85 decibels.
The hearing conservation program must include noise monitoring, audiometric testing, hearing protection, training, and recordkeeping.
OSHA requires employers to make hearing protectors available to all workers exposed to an eight-hour time-weighted average of 85 decibels or above.
NIOSH recommends a recommended exposure limit of 85 decibels for an eight-hour time-weighted average, with hearing protection required at or above this level.
State OSHA plans may have additional noise exposure requirements that apply to salon environments.

Noise management reflects the environmental safety awareness that the MmowW assessment evaluates.
Download a sound level meter application on your smartphone and measure noise levels during peak blow-drying periods. If levels exceed 85 decibels, your salon has a noise hazard. Ask staff whether they experience ringing in their ears after work, difficulty hearing in noisy environments, or a sense that their hearing has changed since starting salon work.

Conduct noise level measurements during different periods of the workday using a sound level meter or calibrated smartphone application. Measure during peak blow-drying periods, during quiet periods, and during average activity. Measure at each workstation because noise levels vary by location. Stations near the blow-dry area experience higher levels than those at the far end of the salon. Record measurements and compare them to OSHA and NIOSH exposure limits. If any measurement exceeds 85 decibels, noise controls are warranted.
Step 2: Reduce Noise at the Source
Replace older, noisier blow dryers with newer models that incorporate noise reduction technology. Modern professional dryers rated as quiet operation typically produce 70 to 80 decibels compared to 85 to 95 decibels for older models. Maintain all equipment to prevent noise from worn bearings, loose components, or clogged filters. Position background music speakers to provide even coverage at moderate volume rather than concentrating sound from a few loud speakers. Set a maximum volume level for the music system and communicate it to all staff. Consider acoustic treatments such as sound-absorbing ceiling tiles, wall panels, or partitions that reduce sound reflection and lower overall ambient noise levels.
Step 3: Organize Work to Reduce Exposure
Schedule appointments so that the number of blow dryers operating simultaneously is distributed throughout the day rather than concentrated during peak periods. If possible, designate a specific blow-dry area that is acoustically separated from other stations, allowing stylists not actively blow-drying to work in a lower-noise environment. Rotate blow-dry duties among staff to distribute noise exposure rather than assigning one stylist to perform all blow-dry services. When not actively blow-drying, move away from the blow-dry area to reduce exposure during other staff members' drying services.
Step 4: Provide and Train on Hearing Protection
Make hearing protection available to all staff who are exposed to noise levels at or above 85 decibels. Options include musician's earplugs that reduce volume evenly across frequencies, maintaining the ability to hear conversation and music at reduced levels. Standard foam earplugs that provide maximum noise reduction but may muffle conversation. Custom-molded earplugs that provide comfort for extended wear with specified noise reduction ratings. Train staff on proper insertion and use of hearing protectors. Provide multiple options because fit and comfort determine whether staff actually wear protection consistently. Emphasize that hearing protection during blow-drying does not prevent communication because blow dryer noise makes conversation difficult regardless of whether earplugs are worn.
Step 5: Monitor Hearing Health
If noise levels in your salon consistently reach or exceed 85 decibels, consider implementing baseline and annual hearing tests for staff. Baseline audiograms establish each person's hearing level when they begin work. Annual audiograms detect early hearing changes before they become symptomatic, allowing intervention before significant damage occurs. If a significant threshold shift is detected, evaluate the staff member's noise exposure, verify that hearing protection is being used correctly, and consider additional noise controls. Even without a formal hearing conservation program, encouraging staff to include hearing evaluation in their annual health checkups raises awareness of hearing health.
Step 6: Educate on Cumulative Exposure
Help staff understand that noise exposure is cumulative across all sources, not just salon noise. A stylist who works in a noisy salon for eight hours and then uses earbuds at high volume during their commute and attends a loud concert on the weekend is accumulating total noise exposure that exceeds safe levels even if the salon exposure alone is within limits. Encourage staff to protect their hearing outside of work as well, using volume-limiting settings on personal audio devices, wearing hearing protection at concerts and sporting events, and recognizing that their occupational noise exposure reduces their safe tolerance for recreational noise.
OSHA requires hearing protection to be available at 85 decibels time-weighted average. NIOSH recommends hearing protection at the same level. In practical salon terms, if multiple blow dryers are operating simultaneously and you need to raise your voice significantly to be heard by a person standing three feet away, the noise level likely exceeds 85 decibels and hearing protection is advisable. A sound level meter measurement during peak blow-drying periods provides objective data. Even below 85 decibels, staff who experience symptoms such as ringing in the ears after work, a temporary sense of muffled hearing, or difficulty hearing in noisy environments should use hearing protection as a precautionary measure.
Client exposure to salon noise is typically much shorter than staff exposure, which significantly reduces the risk. A client who sits through a 30-minute blow-dry service experiences a fraction of the cumulative exposure that a stylist who blow-dries multiple clients per day accumulates. However, clients with existing hearing conditions, hearing aids, or noise sensitivity may experience discomfort or temporary threshold shift from even brief exposure to loud blow-drying. Offer clients the option of hearing protection during blow-dry services. For clients who wear hearing aids, ask whether they prefer to remove them during blow-drying to avoid amplified noise exposure and feedback.
Active noise-canceling headphones can reduce perceived noise levels but present safety concerns in a salon environment. They may prevent staff from hearing important sounds such as client communication, fire alarms, equipment malfunction sounds, and verbal warnings from colleagues. Noise-canceling headphones also create an isolated experience that may appear unprofessional to clients. Musician's earplugs are a better choice for salon use because they reduce volume evenly while maintaining the ability to hear speech and environmental sounds at reduced levels. If noise-canceling headphones are used during non-client tasks such as cleaning or stocking, staff should ensure they can still hear alarms and communication from colleagues.
