How loud is 43Db when compared with 52Db. Sorry to ask what seems to me as a slightly daft question but our kitchen is open plan and noisy appliances are not welcome.
I obviously do not own a decibel meter (I am sure they are not called that). So could anyone offer a comparison.
Christian, thanks. It is a 20% reduction which I agree would be very noticeable. My quandary is whether or not 52db would be invasive in an open plan kitchen/dining area, but this could be subjective anyway.
Appliance in question is a dishwasher (we do not have one currently). The comparison is between an AEG (43db) and a Bosch (52db). I have no data on our existing Hotpoint washing machine to see what noise rating that has.
Bob, thanks for that. I have been googling all afternoon comparing prices and spec of kitchen appliances search as you have never crossed my mind. Thanks.
It's almost 10 times quieter. However, the figures, and the behaviour of the ear are logarithmic (approximately).
The difference between the figures is important, as is the method of measurement and the distance. Unless these are the same, you can't compare the figures.
Assuming that the conditions are the same, then if noise is a concern, this is a difference worth having.
If you give the average person a volume control and get them to set it to half the level, and then measure it, it will be about 10 dB, so the difference between 43 and 52 is, in practice, a great deal.
It isn't a 20% reduction. The different between 52 and 43 is the same as the difference between 10 and 1. It is even the same as reducing 5 to -4. It is reducing the power of the noise by a factor of 8. Ears have an amazing dynamic range, so it won't actually be perceived as an 8 times reduction. I would guess it will sound about half as loud.
Missing from the table shown previously in thread is a garden vacuum cleaner (for sucking up leaves etc). It is about 250db (oh yes it is - especially at
8:30 in the morning and I work nights sometimes). Nice neighbours eh! :-)
9dB difference. 3dB is a doubling, which is also roughly the smallest level that you'll notice. So this is about "3 subjective notches" louder.
43 dB is a "typical room" sort of level. 52dB is "outdoors on a city street".
(Yes, and I _know_ that dB aren't an absolute measure)
We have a 46dB Dishwasher (Bosch) and its very quiet - much quieter than the one it replaced - this was also a Bosch but 20 years older (never went wrong) and we gave to a friend 30 months ago, who still runs it twice a day in a B and B !! (its well shagged though now !)
46dB is quiet enough to have a normal conversation 4 feet away in a quiet room and only notice its on when someone points out it is on - not even obtrusive - it was selected for its quietness as its in the kitchen / diner where the family seem to spend most of their time !!
One decibel is DEFINED as teh smallest difference in sound you can hear volume wise. Or was, Then they took the results of teh tests and expressed it in energy per squarte foot or something.
Nah, thats more lke 85dB
43dB is quite. 52dB is quiet converstaion when you don't want to be overheard.
db sometimes ...dBA at others ....the dBA is used more often as the human ear is not as receptive at some frequencies as at others. The dBA values take this into account. There are also other db variations.
We got the model below that one - 51db - and most of the time you don't really know it's on, and the kitchen is the quietest room in the house in relation to traffic and other noise. We get more noise in the front room from someone passing in the street :)
That's *passing* for any of you that might think summat else :oD
If the dishwasher is anything like their washing machines then go for a different make. We have a Bosch and it's VERY noisy. Even Which magazine points that out even though they recommend it.
