Psychological effect caused by spin noise

[thomasortega]

Guys, I have a little question for you.

On modern machines, does the spin noise cause any impression about it's "spin performance"?

For example, a machine that spins at 1400 RPM silently will make you think it extracts exactly the same amount of water than the same machine making a jet engine noise ou the noisier machine will cause some psychological efect that makes you think that the clothes are better spun?

No, also because in my experience faster spinning machines are less noisier than slow spinning ones, all that changes it the pitch (or tone).

no

at least I always feel like it is faster when sounding like a jet xD

All I know is the is the noisier the machine the faster I want to get rid of it. If it is noisey on the spin I do not want it.

A potential psychological effect would be the relationship between spin noise level and perceived build quality - the lower the spin noise, the better the build quality. As for the spin speed itself, I think it's sufficient to see on the fascia how fast the washer is supposed to spin.

Sound design is a science to itself. I saw an interview on TV several years ago, where Miele people said they could design a washer that makes no sounds at all. However, people would want to *hear* their laundry being washed and spun so washers and dryers etc. are designed to give off just the right sounds during each phase of the cycle. Thinking about it, Miele washers actually do make a nice filling sound - not the usual shhhhhh but more like.... like water gentle being poured into a cup.

Personally, I prefer quiet appliances and crunchy cornflakes, which, of course, are sound designed to give the right crunch... ;-)

Logixx, that's exactly the point.

I'm trying to reach the exact point.

If the it sounds like a dentist drill, the machine will cause the psychological effect of cheap, low quality and annoying.

It it sounds too stressed, like a truck engine, the psychological effect is thinking that something is getting jammed and the motor is suffering some kind of overload.

The idea is create the perfect sound (using the cooling turbine on the motor) loud enough to cancel the intermitent and random noises from the pump, suspension, water splashing agains the outer tub, etc. without being too louder. AFAIK, 1db louder on the right frequency is enough to cancel other noises and make the machine quieter.
After that, the question, can a certain sound cause the psychological "better spun" effect mentioned above?

but... how can we discover the proper sound?

My favorite spin noise was the old Bendix with two speeds and the old Kenpool combos. Currently, I have a couple newer Frigidaire Infinities that spin 1100 RPM and sound a tad bit similar to either of the previous said models.I always prefered a major high speed spin because it cuts down the drying time and holds the aroma of the detergent used.I just got off line looking at the new L.G. 5.1 cu ft front loaders. Gotta get one!!They now have three spay nozels. Two on either side and one up top that thoroughly rinses the clothes.
