Help me understand the difference between 28dB, 38dB and 48dB.

Help me understand the difference between 28dB, 38dB and 48dB. I'm thinking about buying a fridge, and the fridges I'm considering have noise levels ranging from 28dB to 47dB (according to the latest fridge assessment in Choice). Fridges with a 28dB noise level rating are too expensive for me, though, so I'm trying to find something I can afford but which won't annoy me too much (I'm sensitive to the noise of a buzzing fridge). What I can afford tends to be somewhere in the mid-30s dB range. But it's no use going into a noisy showroom and trying to properly gauge how a fridge will sound in my quiet home. So I'm wondering if there's a way I can test these different noise levels at home before I buy, to see what's the difference.

Earplugs/muffs to block out a crying baby

In the next two weeks, there will be a new addition to our household -- a baby. (Not mine.) And since it's not mine, I would prefer not to hear it. There are lots of AskMes about earplugs, but many (like the ETY ones) use as a selling point that they don't muffle speech. I want to muffle everything. Best ear protection for the job, <$30?

Sorry for the morbid question.

Hospice and palliative-care providers often tell patients' families and friends that as people die, hearing is the last sense to go. Is there any science behind the claim? [more inside]

Sounds just fine

If sound were to travel closer to, say, the speed of light than the speed of sound, would we still be able to determine its horizontal direction? [more inside]

TeachingHearingFilter

I'm going to be teaching about sound and hearing to some 12/13 year-olds next week and I'd like to show them how it's impossible to talk if your speech is relayed to your ears (by headphones) half a second or so late. How can I implement this in software? [more inside]
