My ideal in regards to noise in my sleeping or waking hours would be to create an environment in which human noise is minimized as much as possible and non-human noise is all or most of what is heard. When I'm camping, other than the humans I'm camped with, I hear the river, birds, and other wildlife, and occasionally an airplane. That is as natural as it gets for me, and I imagine that sounds of water, wind and wildlife are all that our ancestors heard the majority of their lives. I sleep incredibly well while camping, but at home, being unable to recreate the sounds of nature, I prefer music by day, silence by night.

I don't know about everyone else, but noise freaks me out. I HATE loud man made noise. I don't know if I get over stimulated, or what, but I literally get agitated and have a hard time functioning. I want SILENCE. Noise drives me nuts...

What is natural for one person is against another one's nature. Be true to what you are, regardless of what others say is normal or natural. Even if you feel you want to change what you are to something different, acknowledging your nature at this very moment will save you a lot of trouble.

Partaking in this kind of music is natural.

Listening this kind of music isn't natural, but it's awesome.

If you did it all day, there'd be something wrong. Low level sounds are natural, but there is a reason we react to loud sounds.

Music is as distracting as noise: http://www.ncbi.nlm.nih.gov/pubmed/11964204

My kids sleep through lots of noise. Although, since being babies, they have always had a startle reflex with unexpected sounds.

I take my cues from them mainly as to what's normal iykwim!

People comment on our noisy letterbox and a neighbour (who had a hearing impairment) has complained about the wind noises in his house. I sleep through most weather, but was woken up once with a massive clap of thunder (to be expected I'd say).

I think that depending on each individual, we're adapted differently - some of us may be more sensitive than others to loud noises.

I don't think that silence is all that common or normal, but perhaps some people (perhaps someone with ASD?) may need a quieter sleeping environment than another?

I work in a noisy environment all day - usually music, and it could be two or 3 different kinds of music at any given time. It drives me NUTS! I cant wait to get home to: 1) a quiet apartment with the creaks, neighbor footsteps, and fridge buzzing that I'm used to or , curled up next to husband sleeping and a train whistle outside Best of all is if it's raining outside - HEAVEN!

As far as what wakes me up, the usual construction stuff, and neighbors arguing. The most annoying by far was when we had neighbors that played very loud mariachi music late at night. I'm not joking when I say it made me hungry. After growing up going to Mexican restaurants, it was almost a Pavlovian response to want chips and salsa!

The theory may be true with regard to people living in rural settings, or closer to the earth in general, sure. Silence on my parents farm is a noticeable event like you describe -- suddenly you don't hear other birds, squirrels, etc. Look up, and a hawk or owl is overhead. But that's very different from wishing for silence in a city. I live in New York, and I leave the city to have some relative peace and quiet. While the theory may be right that we evolved to have some noise, we aren't evolved for ceaseless urban noise.

If I recall correctly, in that episode Dan wasn’t necessarily saying music was the antidote to silence, even though the context was that Marco was talking about listening to music while working. His theory was more towards noise in general, and in fact I think he mentioned that music could be distracting. Keep in mind that even in the “quietest” environment there is often some sort of background noise, such as an air conditioning vent or people chatting in the background etc.

Shortly after that episode I downloaded WhiteNoise, and holy crap has it made a difference in my ability to fall asleep. Before using that app, it would always take me at least half an hour to fall asleep; ever since using that app, I almost always fall asleep within a half hour. Probably helps that it kind of replicates my childhood, where during the summers it would be 120 degrees with no A/C so I would have to leave my windows open and listen to all the wind and wildlife while trying to fall asleep.

We live in the country where it is very quiet. On summer nights, you can hear the train going down the tracks 10 miles away and the Friday night car races, which are about 8 miles away. Visitors always remark on how quiet it is.

At night, we always use a "rain machine", just to drown out any sounds of cars, neighbors, etc.. since sound does travel so far out here. If we didn't use it, we'd be waking up every time a car goes down the road.

I tend to agree with that theory, especially because my dogs go on alert every time they hear an unusual noise. You become accustomed to the natural sounds and anything out of the ordinary really gets your attention.

One of my favorite things in life is to experience the total silence of the desert. There are times I think I actually need to experience it every now and then. Conversely, I think that people feel overly entitled to make noise that others can hear. Loud mufflers, blasting music, and horn honking that has nothing to do with avoiding danger are all sonic forms of marking territory - no less brutish than marking one's turf with bodily fluids.
