Noises in nature don't bother me (unless I hear that certain sound a large tree makes when it's about to break and come down in an unpredictable place... this can be quite dangerous!). I hear mountain lions, coyotes, big owls. Birds follow me around, because I often share crackers or bread with them, so they know me and start "reminding me that they're hungry." Sounds of forest, ocean, desert are sounds I love and no, I am not afraid at all. I'm alone in nature and suddenly hear a human sound and my heart seems to fall into my stomach. Very odd, indeed.
I love music, unless it is ridiculous throbbing bass that threatens to destroy one's ear drums as someone drives by. This is one I've never quite figured out, especially when it's a guy on a motorcycle!
Camping is something I do in isolation or don't do at all. I went to Monument Valley four years ago and pitched my tent on a ridge, all alone. The Navajo people, they let you be. You go off by yourself, away from where the tourists drive in with their RVs and all is well. If you do not want to hear or see people? You speak to the Navajo when you enter Monument Valley and they will tell you where the tourists will not be. You must be very self-reliant, willing and able to hike and pack food, tent, sleeping bag, and water in and be truly good about cleaning up your camp site (please!). There are outhouses, but you must hike to where the tourists park way up in a lot to find and use them. It is "rough camping". I was a woman traveling alone and had no problems. I cannot say the same was true at "white man's" camps, where I was nearly molested on two occasions at two different USFS camps. Native Americans do not behave like many other people (this is meant as a DEEP compliment!). The white man's camps are invariably more crowded, noisier and there is alcohol. On the Native reservations, alcohol is not permitted.
Sounds I cannot handle: the sounds of drunken people. Revving engines and screeching tires. Gunshots and other explosions. Loud TV or radio announcer voices coming from another room.
