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.

Anyone else with hyperacusis

Why does my pot of water sound like it's boiling, but when I lift the lid nothing's happening yet? What's making all the noise?

The clichéed two-part catcalling whistle that is performed at the sight of a hottie -- almost exclusively a man whistling at a woman -- that sounds like this
. Rising, then falling. Where did that particular "tune" come from? What is the earliest recorded instance of its use? How was it popularized?

Noise-canceling headphones, or noise-cancelling earbuds, or earmuffs, or earplugs, or some combination? I need to protect my ears from both subway noise and loud co-workers. [more inside]

I just microwaved a mug of water. And after about a minute it started making a loud humming noise, like what happens when you run a wet finger around a champagne glass. It sounded like there were aliens landing in my microwave. What happened? [more inside]

Every few days there is a huge BOOM! that seems to emanate from Boston Harbor. It really echoes throughout downtown. What causes it?

I have a pretty bad case of night terrors. I am turning to the hive mind to help me identify a cheap and effective solution/device that will record the times when I'm audible throughout the night. I don't want to know what I'm saying as it sometimes freaks me out (nothing scary, I'm just weirded out by listening to myself yell/whisper subconciously). So a tape/voice recorder is out of the running.
In short, I need to know what time I make noise, and maybe a little squiggle or number on a piece of paper/read out screen letting me know how loud I was relative to the rest of that night (I'm thinking of the needle that scrbbles on rolling paper with a time stamp next to it like a seizmograph).
Any suggestions? This can be hand made or purchased as long as it's not too expensive :-)

I have a problem with hearing bass music vibrating through my windows and walls into my home. It literally echos through my every vein and makes me feel insane. Is this a sign of age? Is something wrong with me? [more inside]

In my office there is a small conference room, 81"x96", maybe 18' ceiling. The walls are sheetrock. The echo is extremely irritating. In order to quiet the room a bit I want to mount squares of corkboard, 12"x12"x1/4". I will use 12 to 20 of these squares on one of the 81" walls.
Will this be reasonably effective in lessening the echo?

I'm looking for cheap, deep-in-the-ear earbuds for listening to audiobooks. The sound quality doesn't have to be great, because I won't use them to listen to music. I want cheap ones, because I inevitably break headphones, and I don't want to have to spend $100 every month. On the other hand, I'm willing to spend $20 a month if I have to. In-the-ear, because I don't want to keep my wife awake with "leaking" sound. [more inside]

What is the most effective way of reducing the sound of other people: voices, music, traffic, all the stuff that encroaches on silence. Is there a really efficient earplug or headphone that will work or some external machine that will counter noise effectively?

At a recent lecture, I taped from the soundboard & from some microphones. I meant to record these to separate channels, but I accidentally left it in low quality mode - mono, 22khz. It sounds like video got thrown into the mix. Can I salvage the audio? [more inside]

My CRT monitor puts out a high-pitched whine that changes tone depending on certain conditions of which I'm not familiar with (in other words, the tone fluctuates). It's not overly loud but it's definitely noticeable - it's quite irritating. It used to do this about a year ago then stopped only to start again last week. Anybody know why it's happening and how to stop it?

I have a Marshall Valvestate 20 (8020) practice guitar amp. The built-in reverb has stopped working, producing just noise when you turn it up and a sort of wobbly sound if you bump the amp. Also the amp itself has a lot of hum, which goes away when I touch the strings. I'm too cheap/broke to get it fixed but know how to use a screwdriver and a sodering iron. Suggestions?
