Tumble Dryers – Sounds and Vibration
If you want an undisturbed evening or a peaceful night’s sleep, quiet appliances can be very important, particularly in a small home.
As tumble dryers can be fairly loud, paying close attention to the noise level is vital when it comes to picking the right one for you.
Using the Listed Decibel Level
When talking about the sound levels of an appliance, people often use decibels (dB).
The higher on the decibel range an appliance is, the louder it sounds. As a few points of reference, 15- 30 dB is approximately the noise level of a whisper, 60 dB is around the level for a normal conversation, and a lawnmower is around 90 dB.
Different tumble dryers come in at very different sound levels on the decibel range. The lower end tends to be around the 40 dB level, while some go up to 80 dB or more. Tumble dryers that are claimed as super silent are often below 45 dB.
Using the listed decibel sound level can be a very good way of picking a quieter product, but it’s worth noting that appliances that have a lower dB level can sometimes sound louder than models higher on the scale. This is because the dB range only measures sound intensity, not frequency. Tapping a table surface and tapping a glass or tin could have the same dB level, but because the frequency is different, one can sound louder than the other.
Tumble dryers are also tested in “ideal” environments, and chances are your utility room or kitchen is not that ideal. As such, appliances may sound louder than the number of decibels suggests, depending on the amount of reverberation or echo in the room.
Designed to be Quiet
As tumble dryers have lots of moving parts, they tend to be quite noisy, but there are some that have features which reduce the noise level.
Models that come with inverter motors tend to be much quieter than those that don’t. This is because a lot of inverter motors don’t have brushes, which means less friction is generated when the motor is running. With less friction there is less sound made by the appliance, resulting in less disturbance for you.
Some tumble dryers have built-in insulation too, which reduces the amount of sound that escapes.
Models that come with inverter motors tend to be much quieter than those that don’t.
As the tumble dryer spins, a lot of the sound comes from the appliance vibrating. Some brands have developed technology which helps reduce the amount of vibration.
Siemens have incorporated AntiVibration technology in the side walls of some extraKlasse models. This helps stabilise the dryer, reducing noise.
You can also do a couple of things to limit how noisy the vibration is yourself.
Investing in anti-vibration feet pads or a mat can be very effective. These absorb and isolate a lot of the vibrations generated by a tumble dryer, reducing noise and stopping it moving around. They can also help address wobbly dryers as they cushion the floor, reducing the likelihood of rocking.
Extras to Bear in Mind
Noise can be very personal and subjective. If you tend to be quite sensitive to noise, investing in a tumble dryer that has a lower dB level and some sound reducing features is probably a good idea.
It’s also worth noting that there can be other factors that make your appliance much louder. If a zip comes into contact with the glass of the door, for instance, the tumble dryer will sound much louder than it should.
Understandably, the most effective way of being undisturbed by your tumble dryer is to locate it suitably. Positioning it in a utility room or garage reduces the chance of you hearing it. If you have to keep it in your kitchen or have a small home, investing in a super silent model is much more important.
