How much noise does a vacuum make?
Sound is measured in decibels. The more decibel, the louder the sound is. On average, as people we hear noise between 0 and 120 decibels. 0 decibel does not mean that there is no sound, only we do not hear this. Above 120 decibels we hear clearly, but can damage our hearing. Manufacturers of vacuum cleaners measure this in the average suction position, with the most regular brush head. The sound can therefore differ when you use a different attachment or switch on a turbo mode.
It seems like a clear story, but unfortunately that is not entirely true. Decibels are in fact quite difficult to interpret. Because how much noise is 64 decibels? And what is the difference with 67 decibels? Or 84? Most companies use situations to compare decibels. For example, a starting aircraft makes a sound of 140 decibels, the music in a nightclub stands at 105 decibels on average and a dripping tap creates 20 decibels of noise.
What do I think of that?
To be honest, I still found it very difficult to understand how hard my 67-decibel vacuum cleaner sounds when a starting aircraft produces 140 decibels. With these examples I still did not understand how much noise my vacuum cleaner makes. In theory, a vacuum cleaner of 85 decibels is comparable to 'noise in the schoolyard' or 'a busy road with cars'. Because this was still too vague for me, I started testing myself.
Vacuum cleaner test, 1, 2, 3.
Vacuum cleaners that produce less than 60 decibels of noise are called silent. This does not mean that they are noiseless, but you can still hear the TV or sing easily with the radio.
We normally call a noise level between 61 and 70 decibels. The TV or radio you have to put a bit harder but a conversation at 2 meters distance from each other is still good to do.
Vacuum cleaners with a noise level between 71 and 75 decibels are loud. To have a conversation with someone 2 meters away you have to raise your voice considerably. It is also not possible to hear the TV without raising the volume.
More than 76 decibels of sound we call very loud. It is then no longer possible to have a conversation without raising your voice and you hardly hear the TV or radio anymore.
Vacuum cleaners with different decibels of sound I tested separately in the average suction position, armed with a decibel meter. Being able to hear the TV or having a conversation at 2 meters distance were the starting points. This seemed to me the most relevant when you are vacuuming. On the basis of this test we have divided all vacuum cleaners into 4 categories: quiet, normal, loud and very loud.
Vacuum cleaners make noise, even the quietest vacuum cleaner you hear when it is switched on. Vacuum cleanse regularly when the children sleep or on a Sunday morning, then a silent vacuum cleaner is recommended. In addition, 64 decibels with one vacuum cleaner is not annoying, although another vacuum cleaner of 64 decibels seems louder with a higher beep. So be aware of the fact that a vacuum cleaner makes noise, then the risk of disappointment is a lot smaller. And that's what we want.
