loud can be peaceful, shril can be nerve-wrecking
This thread is highly entertaining (speaking of how one person perceives the same vacuum a different way than another).
For my own vacs I found the loudest:
- Hoover Celebrity single speed UFO (and unpleasant)
- Siemens B series standard canister (yet pleasent)
- Vortech Force old model (loud, yet very pleasant)
Somewhat in the middle:
Kirby G4 (quite loud but not loudest, yet very unpleasant esp. in shampoo mode)
AEG 1960s stick vac (may compare to Regina quickbrooms) loud, unpleasant
Vorwerk Kobold 117 with PB (quite loud, yet handsomely pleasant)
Low-voiced or "silent" (if that goes for vacuums at all):
All Electrolux / Lux /Volta machines (and pleasant, too).
Older Kirbys (to some extent at least)
Been thinking for some while to find out how "loud" vacs can sound ok, yet "somewhat loud" vacs sound entirely terrible to me.
Bad guys:
Rainbow E2
All high-amp Hoovers
Black&Decker cyclone cheapo
Newer Electrolux shop models
Dysons
Midways:
All Miele, Bosch, Siemens
Best:
Older Electrolux (door-to-door) and newer Lux models
Metal body Nilfisk bin type (old style)
All Vorwerks before VK 118 (so the older "big-bag" variety)
It all boils down (for me at least) to this:
- the more rectangular the wave of vibration, the nastier (which rules out ALL brushless reluctance motors: Black+Decker bagless, Rainbow E2, newest Vorwerk stick).
Feels like biting on a stuck-up dentist drill in a molar. (NASTY!)
- the more sinusoidal the vibration, the smoother it gets.
(All brush type motors, better yet: induction motors on commercial units.)
Then the dampening between motor and casing:
- The harder the connection the nastier: Hoover Celebrity (the whole body conveys the sound, same with older Juniors and Seniors, worst on all Hoover hardbody uprights as well as ALL Regina canisters with tuna can shape (all that I have seen so far)
- Some dampening rubbers may help (Siemens canisters of the 90s and 80s)
Once the airstream sound is stronger than the motor sound, it feels more "deluxe"
(ALL Electrolux, Lux, Volta, Trident, Vortech Force), so pleasant
Finally, once the different speeds of bearing balls, commutator, brush roll, attached extra devices play a harmonic "chime" within real musik notes (triple or quadruple notes) it can feel VERY pleasant even when loud. There is a tendency towards outer-bag machines, but not always.
Vacs of this kind: Older Vorwerks (1950s to 1970s, the effect vanishing after they had introduced smaller and higher speed motors with the 118 and later models)
Hoover Juniors have the same effect, yet their rattling "hard" vibration transport from motor to casing is dampening this effect.
Kirby models of G4 and up are completely out of this: On carpet mode, they sound somewhat ok (still), but when in shampoo mode, they are a nuisance: This shrill, choked-off air stream fighting its whine against the likewise shrill commutator sound (just a few half notes underneath) and all this combined with the weeet-weet of the gear transmission, that is too much for me.
I deliberately use ear plugs on Black&Decker, Rainbow E2 and Kirby shampooers.
(Btw. all reluctance type motors produce a similar shreaking and grinding voice without any extra attachments at all).
I refuse them, the have a ban in my house.
Musicians here? What do you think?
Not a musician myself, but I just LOVE this medium-level harmonic hum (say "ooommmm", the one that makes you hum along and zone out) together with a FAT rush of air (to tell you it is the AIR that does the job, not a fire siren). Dampened of course (you have to have the feeling the beast is WITHIN, but outside (where you are) there is just stealth work (and a very powerful one!).
"It's the tone that makes the music" (saying)
Opinions?
