There are many reasons you may need a commercial toilet hand dryer to have a low noise level. Especially if you are choosing a hand dryer for a school where the age of the child or acoustics of the building are a factor in selection. Reported dB levels are not always accurate in reality due to so many variables in testing. That's why we offer a demonstration service where you can try hand dryers in your location to get a feel for the noise level before you make a purchase. Contact us here to find out more. Mitsubishi Jet Towel hand dryers are often selected by noise-sensitive locations as they are not only high speed hand dryers, they are also easy on the ear. We also have a number of hand dryers with the Quiet Mark accreditation including the popular Dyson V blade hand dryer which have been approved by the Noise Abatement Society.

The main reasons for this are the speed of motor and the characteristics of the air outlet. First and foremost the job of a hand dryer is to of course dry the hands, and the quicker the better. Some blade hand dryers were the original fast drying but high noise units. They have now come a long way in being great performing with reduced noise. There's always going to be a trade off between dry time. energy efficiency and noise level. The key is to find a unit that has the perfect balance for your unique requirements. Also, some hand dryers have a higher pitch than others, which means that noise transfer through walls is lessened, so may be an important consideration in libraries, offices, care homes etc. As stated above, it's best to actually get a unit in the place it is going to be located before making a decision, so please do not hessite to book a demonstration with us to try before you buy.
This is all dependent on the demographics of the user and the type of building. As yet, there is no such thing as a completely silent hand dryer. But there are ones that produce very little noise. The problem with these is that they usually take a very long time to dry the hands, with low motor speed and reliance on energy-hungry heater elements to evaporate water off the hands. There are many low energy hand dryers that have sacrificed a little motor speed to reduce noise levels as well as utilising modern design and technology. However, we understand there may be a need to compromise totally on other characteristics for the lowest noise possible, as even the old style conventional hand dryers will still save significant amounts of money and reduce carbon production compared to the constant use of paper towels. A great hand dryer that is one step up from the conventional hand dryer that is worth consideration is the Dryflow Elite hand dryer, a favourite with schools and installed in the Eureka National Children’s Museum.
Some hand dryers like Dryflow G-Force MKII, Mitsubishi Jet Towel hand dryers, Turboforce hand dryer, Jet Force Junior HEPA hand dryer, Dryflow Viper and EcoSlim HEPA hand dryer have settings and dials to manually adjust the motor speed. These are ideal because you can customise to your own requirements and are great for buildings that require the same looking hand dryer throughout a building but have some areas of the location which are noise sensitive and others that aren't.
Can you trust the decibel (dB) number stated by manufacturers? Hand dryer manufacturers measure sound levels in terms of decibels dB(A) at a distance of 1 or 2 metres, in a sound proof chamber. This does not take into account the increase in noise when hands are positioned under/in the dryer or when the sound bounces off walls. Therefore you can not always rely on the figure presented to you and need to actually get the hand dryer in location to test for yourself. Contact us here to book a demo to try before you buy.
Quiet Mark certification is the unique consumer and trade champion mark of approval for products, providing reliable and independent information about the sound a product makes and approved noise reduction performance before purchase. If a product has the Quiet Mark it can be considered as quietest in its class whilst still performing the job it was intended to do very well.
Quiet Mark works in association with the noise abatement society. They state that the level of declared decibels is often not easily interpreted as to how loud something will actually be experienced. Sound is perceived differently in different places, at different times, and often dependent on an individual’s emotional response to that particular sound.
Quiet Mark conducts assessments and acoustic measurement of products in the purpose-built Quiet Mark test laboratory and specialist acoustic lab partners for specific product categories. They don't publish decibel levels because the level of a product may change considerably depending on the room it is working in. They state that giving out the definitive dB level of a product may be confusing. In addition, two similar functioning products may emit the same decibel level, however, one may sound pleasant and the other sound unpleasant and irritating. This will not be reflected in the decibel measurement.
