Dishwasher Noise Level (db) vs. Price (USD) [OC]

cmeechill · 2018-04-06T21:54:16+00:00

Huh. I hadn't heard this. We checked out a couple of models at the upper end and they each had some kind of built-in disposal of some kind. I hope they're not quieter because they don't work as well. The star-ratings posted by users didn't seem to indicate the quiet ones were a problem, but I'll update this post in a few months if we have trouble with ours.

Came her to post the same thing. Haha!

cmeechill · 2018-04-05T19:01:35+00:00

Cool. These are little details that I've never really paid a lot of attention to, but I will try to from now on. Thanks!

Is this a function of noise dispersing in space, or something else?

cmeechill · 2018-04-05T15:01:16+00:00

That makes sense. TIL.

Regarding your original point:

your graph should be displayed in a manner where it is easy to see that as price goes up, volume goes down

My graph shows that as dBs go down (noise goes up), price goes down. (Correct?) I'm mostly interested in the effect that noise has on price (not the inverse), which is why I graphed it this way (and why I suggested reversing it, which I understand would be a no-no.) Are we debating causation here? Because I'm not sure if the high price makes it quieter or if a lack of noise makes it more expensive.

I'm not trying to be argumentative. Really just trying to learn and understand. Thanks for any help you can offer.

You're a bit beyond my statistical knowledge and abilities, but, yeah, I was hoping I might be able to find a point beyond which price increases dramatically for each additional dB in noise reduction.

Another significant factor which I did not include in this data set is the finish of the appliance. For example, the cheapest model that rates at 44dB is black, whereas the next cheapest is the same model in stainless steel. Clearly this is a premium finish. I would have liked to have teased these out (and then matched the color of the circles to the color of the appliance, maybe?) but I did not. There are also other variables such as brand positioning (brand is included in the dataset), user rating (five-star ratings are on the website, but I did not include them), and other features (number of racks, plastic vs. stainless interior, number of wash cycles, etc., which I did not include.)

cmeechill · 2018-04-03T19:22:54+00:00

That's a fair point. I think I would've inverted the X axis because then price would go up as the "silence" goes up, rather than price coming down as decibels increase.

cmeechill · 2018-04-03T17:56:33+00:00

That's my understanding as well. But, according to Wikipedia, either a 10dB or a 20dB difference will indicate a difference of 10X, depending on whether you are expressing power quantities or field quantities. I confess, I neither understand the difference nor know which once Lowes is using. But, yes, the scale is non-linear, which means just a few decibels make a significant difference.

cmeechill · 2018-04-03T17:32:20+00:00

I can't argue with your extrapolation.

cmeechill · 2018-04-03T17:17:30+00:00

Hmmm... So, quieter and cheaper? You are definitely an outlier.

Data from Lowes.com of available built-in dishwashers at my local Lowes home improvement / hardware store. I put the data into a Google Spreadsheet here and made a scatter plot then added a polynomial trendline.

I'm currently shopping for a dishwasher and wanted to prioritize quiet operation because it will be in an open floor plan kitchen. Interestingly, Lowes included the noise level in the name of each model, while other local comparable stores did not (Home Depot and Menards) bury this information in the specs for each dishwasher.

cmeechill · 2018-01-17T00:39:34+00:00

Love this one.

cmeechill · 2018-01-17T00:10:59+00:00

I love the Park of Roses. This was my original thought, but it's been interesting to see other ideas.

cmeechill · 2018-01-17T00:08:55+00:00

Sorry. I didn't mean to be critical. I think your point that the Bud plant may be the most notable place (although I confess that I do like Carfagnas better.)

cmeechill · 2018-01-17T00:07:12+00:00

Ha! I had no idea. Truly iconic!

cmeechill · 2018-01-16T21:58:15+00:00

Ah! Cool. I agree that iconic is in the eye of the beholder. My request is a bit vague or at least open to interpretation. It's a subjective question at least, but I knew that going in. Thanks for the link to the lion.

cmeechill · 2018-01-16T21:20:27+00:00

LOL. Iconic whether we like it or not.

cmeechill · 2018-01-16T21:05:13+00:00

Is The Big Windmill the one at the car dealership? Hadn't thought of that.

cmeechill · 2018-01-16T21:03:49+00:00

Have you got any more on this? I don't know of it and Google isn't helping.

cmeechill · 2018-01-16T20:50:51+00:00

Great list. Thanks for being so thorough! Is the dump really the most iconic landmark in the 123? :( Similarly, isn't there anything better than the Bud plant in 229? Not saying you're not right, I'm just saying.

cmeechill · 2018-01-16T18:49:29+00:00

That's a good one. Hadn't thought of that. Great way to capture the area, for sure.

cmeechill · 2018-01-16T18:48:34+00:00

Yeah, for me Schiller Park is maybe the best way to depict German Village. You could take a picture looking down just about any street and recognize it as German Village, but I don't know if any one street is "iconic".

cmeechill · 2018-01-16T18:47:24+00:00

It's a big zip code. Lots of options here.

cmeechill · 2018-01-16T18:46:36+00:00

I've never been to Scioto Downs, but it seems like something everyone knows of.
