Salon Noise: Measure the Day, Not Just the Dryer
The dryer switches off and the room suddenly feels quiet. You return to scissoring, answer a question and prepare the next dog. By the end of the day, it can be difficult to remember how much time you actually spent in the noise.
That missing time is worth measuring. Noise exposure depends on level and duration, including the noise around you while someone else is drying.
A small dryer study found a substantial range
Researchers measured four professional forced-air dryers at one metre under typical operating conditions. Average A-weighted levels ranged from 94.8 to 108.0 dBA. Each dryer was sampled for five minutes using calibrated equipment. Read the original research.
The study was published in 2012 and assessed those particular dryers. It is not a current ranking of every dryer, a measurement of your salon or a VUNRO product test. It also did not establish a safe exposure threshold for dogs. Its practical contribution is showing why grooming noise deserves a measured assessment.
Three decibels is a meaningful change
NIOSH recommends an occupational exposure limit of 85 dBA averaged over eight hours, using a 3 dB exchange rate: each 3 dB increase halves the exposure duration for the same recommended daily dose. Under that model, 85 dBA for eight hours, 88 dBA for four hours and 91 dBA for two hours each represent the same dose. Read the current NIOSH explanation.
Those examples explain the relationship; they are not a promise that exposure below a particular number is harmless to every person. They are human occupational recommendations, not dog-hearing limits or a substitute for the requirements that apply in your country.
Measure the person’s day, not just one machine
Begin with a simple task map. Note where the bather works, where finishing takes place, which neighbouring dryers are running and where breaks are taken. Include the periods when a person is exposed to equipment they are not operating.
For a proper assessment, involve someone competent in occupational noise measurement. A spot reading can identify a concern; it does not automatically describe a whole day's dose. Measurements should represent actual positions, settings and tasks rather than the quietest moment you can find.
A useful salon log records the station, task, approximate duration, nearby equipment and any change made. Keep customer names out of it. The purpose is to understand the work environment, not to judge a groomer by how many noisy minutes they can tolerate.
Make quiet work genuinely quieter
Look for avoidable overlap. Is a dryer left running during a pause? Does finishing take place immediately beside the loudest wet-work station? Are staff taking their break in a room that still receives the same noise?
Turn off equipment when it is not needed. Consider how drying and finishing areas are arranged, while preserving ventilation, supervision and safe access. Review proposed changes through the actual noise assessment; a partition's appearance tells you little about its acoustic performance.
Correctly selected and fitted hearing protection can be part of the plan. NIOSH recommends providing suitable options and enough attenuation for the exposure, while recognising the importance of communication. Read the hearing-protection guidance. Ordinary music headphones are not automatically hearing protection.
Use finishing tools for the finish, not to compensate for poor preparation
Once a coat is properly prepared, organise the manual finishing stage so you can work without unnecessary dryer running time. Keep the tools you need ready at that station.
The VUNRO 7.5-inch Precision Straight Scissors and 5-inch Coarse and Fine Straight Comb support different parts of outline setting and checking. A suitable additional pair or comb can be useful where several groomers share a station and tool turnaround interrupts the work.
These tools do not protect hearing or solve a noisy-room problem. Their role is to support a clearly organised finishing stage. If preparation still needs attention, resolve it rather than using extra scissor work to disguise the result.
