We're looking at two Bosch dishwashers - one claims a noise level of 50 db,
and the other a noise level of 53 db - the features and functionality are
pretty much the same - there's about a $100 price difference.

Bosch has other, more expensive dishwashers in the mid-40 db range - they
are beyond my price point, but with a noise level that goes that low, maybe
the difference from 53 db to 50 db will be enough to justify the extra $100.

Is there an perceptable noise difference that I'll notice when the 50 db
machine is running versus the 53db machine?

Thanks!

a 100W stereo is 3 db louder than a 50W stereo

However, 10db is perceived as twice as loud.

Do you have a stereo with a volume control marked out in db?
Play some thing at medium-low volume. Move down three db.
3db isn't worth $100 in my opinion, but if you have such a stereo then
you can make your own decision.

You'd never notice a 3db difference.

I'd rather use that $100 for a bunch of teaks to make dirty dishes. You
won't hear much of a difference at all.

In addition, think about how the machine will be used. Most are in the
kitchen where you start the DW after dinner and then go to a different part
of the house while it runs. Unless you are putting yours in the bedroom and
run it at night, who cares about the slight noise difference?

I think there is more than decibels to an annoying sound. The one
with lower decibels might have a different pitch or pattern making it
more annoying than the 'noisier' one.

That said- I doubt Bosch makes a really annoying one as that is one of
the key features folks will comment on to their friends.

I'd buy on features that I can see.

Yes. Depends on how sensitive your ears are. Sound measurements are
not a linear function. Read up on the topic in any standard physics
textbook. If you were a music major, buy the pricier machine.
Otherwise, you may be annoyed or not, so why not get the most cost
effective machine and just close the kitchen door when it's running?

Not everyone has a kitchen door. I can almost turn around and see
the dishwasher from where I sit on the sofa in the living room.
The builder of my little 1948 ranch gave me a pretty open plan for the
time period. My next dishwasher will be the quietest one I can find.

We had a Bosch installed about 5 years ago. They said it was going to
be quiet, but I had no idea just how quiet. We can eat dinner a few
feet away from it and not know it's running until it empties water
into the drain under the sink. We were eating dinner one night and I
heard a gurgling sound in the sink and asked my wife, "What's that?"
She replied that she was running the diskwasher. Noises normally
drive me crazy, so this thing is amazing. I don't know what the noise
spec was. It's model number is SHX46A05UC/14 if anyone can look it
up.

Anyway; with apologies for all the technical stuff, you won't hardly
notice the difference between 53 dbs and 50 dbs.

The tech stuff is interesting. One thing not mentioned though, is the
pitch. The loudness is only of factor in determining if a noise is going to
annoy you. High pitched squealing type noises can drive you nuts no matter
how quite as apposed to a low toned louder rumble.

Yes, there is a detectable difference. "Quiet" has a price, you're
unlikely to find a quiet dishwasher under $800. You can fix
fibererglass insulation or batting around the unit to help even more.
I can barely hear mine until the drain start to gurgle.

This is an item you are going to be using for 10 years plus. Spend the extra
and get something you will love.
Skip going to four movies over the next year to pay the difference. You won't
miss the movie, but you sure will enjoy the quieter dishwasher for the nine
years afterwards.

3dB difference is equivalent to one half of the sound level. You'll hear
it, but it'll not be dramatically lower. It also depends on where its
located (near people having quiet conversations, TV etc). I opted for
50dB and haven't regretted it.

I can't speak to db except to note that the db scale is logarithmic -
i.e. 50 vs 51 is a lot bigger than it sounds.

Our old dishwasher, which lasted a looooong time, made enough noise to
wake the dead. You couldn't watch TV in the kitchen without earphones
when it was running.

OTOH, the Bosch Ascetia that replaces it is so quiet that, at first, I
used to get creeped out: if I listened close enough there was *some*
kind of water-like noise coming from *somewhere*.... and it turned out
that the wife had turned on the dishwasher when I was not looking.

This thing is *quiet*.... and I'm kind of neurotic about noise.

Well, it's been over 6 years since the date of the original question. I
wonder how many movies the OP has missed. 4 years to go on the DW.

i had a bosch dishwasher for perhaps 2 years, it was so quiet i had to feel the machine to see if it was running...

however it was a unreliable piece of junk.

you trade off quiet for cost and huge expense getting it serviced. replacing anything but the fill valve requires disassembling everything.....

after 2 out of warranty failures i took it to the scrap yard. that was its rightful home

how would you express the age of the OP in dB?

One Db is not vety much in sound level. To the ear it should be just
the minimum change that you can detect with average hearing. To get a
an idea about db, for 3 db of change double the distance. Say listen to
something at 2 feet away and then back up 2 more feet. At 8 feet it
would be 6 db of difference and to get to 10 db you have to back up to
20 feet.

I was considering Bosch but my local appliance dealer no longer carries
them. He said it was a good machine for washing, very quiet, but meeded
a lot of service calls.

Bought another KitchenAid and continue to be happy with it. We also use
Cascade Platinum and everything is perfect when it comes out.

Double the distance and the sound level should fall 6db as it falls off
by the 'square' of the distance.

No, 3 dB is 3 dB less. 1/2 sound level us -6 DB. Actual ear 1/2 volume is
-10 dB. Trouble with reading is unknown frequency band. Frequencies between
2-3kHz are more audible. So it's harder to compare different readings,
since the meter is not your hearing response.

Doubling original distance should be 6 dB change. 3 dB is a change of power
by 1/2 or double. SPL is a level specified by power. To double intensity,
like a voltage level, it takes 6 dB or four times the power. Similar to car
acceleration. It takes four times the HP to double acceleration.

Yes, I was off by half or double. Anyway for sound that the ear hears,
going only a few DB will not sound much different.
