I am on a long trek in the Balkans and am sometimes camping when there is no cheap accommodation available. I am not yet very experienced in camping, and at this stage I am normally camping near residential areas for increased convenience (I am typically less than 2km the nearest residential area at any given point on my route) and safety (vs brown bears for example; the small country I am in experienced approximately 10 brown bear attacks between 2000 and 2015).
This time I happen to be on a hillside 30m from the nearest path (which is not heavily used from what I can tell), 60m from the nearest houses, and 250m downhill from a university observatory (accessible via a private road which doesn't come closer to me than about 250m). I have tried to remove the few things I have which could have a smell interesting to a brown bear to a bag hanging from a tree, away from the sleeping area. (Except items containing lithium batteries, which apparently have a smell, because these are valuable items and I expect the bag itself will probably be stolen at some point on my trek or else removed on the grounds of being perceived as an eyesore and not belonging there. I am in a country where wild camping is technically prohibited but generally tolerated as long as it is low-key and not making a nuisance to public order, and there is zero familiarity with or acceptance of the concept of hanging bags in trees to keep them from brown bears from what I can tell; it would just be treated as littering. There is no food in the bag, only things like insect spray.)
At 1am I was woken by the sound of walking and cracking branches around 30m away, quite possibly in the woods and not on the path. I cleared my throat loudly to announce my presence in case it were a bear. I felt like playing a podcast or the radio at moderate volume to further announce my presence and calm my nerves a bit.
Would playing the radio or a podcast (is a person talking) at moderate volume help to discourage a brown bear from walking any closer to my tent, or would it be counterproductive and provoke the brown bear's curiosity?
