I usually spend one to two hours outside. I have chronic pain in addition to tinnitus so this is very important to me. It's not always great for my tinnitus, though, depending on if there are any jerks about. However, it can be very helpful for tinnitus if the people around you aren't crazy. The natural noises and ambience is very soothing and can help block out tinnitus. It all depends on where you live really!
