"Silent" Vacuum Cleaners?

[transatlantic]

I happened to flick over to one of the sales channels on TV the other night and noticed they were selling a "Silent" vacuum cleaner. Not sure how new this concept is, but it certainly hasn't been in the affordable market as far as I know.

With the focus on Health and Safety these past few years, inparticular the trend for better dust collection, I wonder if this could mean the beginning of much quieter tools? I know the situation is completely different between the two cases in that the vacuum cleaners can be contained, as opposed to a spinning blade that needs to be exposed to contact the material to be cut, as well as the fact that most of the noise comes from the cutting action itself.

Still though, the noise pollution issue has to be tackled at some point.

I would'nt say 66db was "Silent".....compared to what? For example, a Festool Midi dust extractor is rated at 72db, only 6 db more and I bet that has a lot more suck/air flow than that Bosch.

72dB is around 3 times louder than 66dB, decibel is not a liner scale, instead it's log base 10.

Marketing ****. Just like "High Definition" or "Ulta High Definition"

..ridiculous names

I'm not having that, HD v UHD, it's 50% more letters, it's got to be better.

I'm with you DB, and my UHD TV volume turns up past 11.

We've had an Electrolux vacuum cleaner for a number of years and it's very quiet. Trouble is we now use a Dyson portable which is more convenient but much more noisy!

72dB is around 3 times louder than 66dB, decibel is not a liner scale, instead it's log base 10.

True in energy terms but not in perceived loudness - c10dB to double perceived loudness.

 

[novocaine]

fair point Jake, but I'm basing it on amplitude not energy. happy to agree that my back of the *** packet calculation is wrong though, double the perceived loudness is still a considerable louder.

cheers.

 

[Jake]

But half again as loud (in perception terms) is closer to the mark

I've had that vacuum for 2 or 3 years, it's not bad at all. Turbo brush for it is rubbish though.

Not really. There's a marked improvement in picture quality and other benefits of UHD over HD, as there was between SD and HD.

 

[RobinBHM]

It doesnt how high the definition, it doesnt improve the carp content on tv.

I meant the names are silly, I know the resolution is better. It's like calling a 128GB hard drive 'ultra high storage', when you know that 256GB is just down the road. Just give them self descriptive names that can be incremented, like 2k, 4k, 8k etc.

Again though, it's just marketing **** as the names High and Ultra I guess will appeal to people

I have used that bosch vacuum, they are NOT silent, also the build quality left a lot to be desired..
the new updated henry model they make now is a lot less noisier than that bosch ''silent'' one.
waste of $ for a junk item if you ask me..

strange how that word got through the filter but less offensive ones don't

anyway it's not marketing hype at all - I've done quite a lot of research into sound muffling, deadening, absorbtion of different frequencies et al and I can tell you that 66db is a lot quieter than you might realise, especially if it's in the lower Hz range.

As for Hi def and Ultra High Def: High def is 1080p - ultra high def is 4k (3840p) or 3.55x higher resolution. I'm pretty sure those with reduced eyesight would argue that 3.5x better is worth having.
