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.
Ralph Mowery brought next idea :
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.Greg
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.
+1
I'm glad to see that the political rants in this newsgroup didn't drive everyone away.
still some good posts
