The sound of a gentle breeze or soft rain wakes me during the night, but that is a pleasant break in my sleep. I can detect the change in wind direction by the volume of the leaves reaching my ears. If a vehicle is idling longer than normal within a 3-4km radius of the house at night I get up and look out the windows. Leaves falling on the patio in the dead of night wake me and I have to investgate to make sure it isn't someone sneaking about. Bugs and baby birds, electrical current before a storm, high and low pressure systems in an environment completely void of any human sound, cicadas and borers scratching their way out of the ground, the swish of a bird wing on the air, termites, neighbours up to 3 properties away vacuuming their house and chopping vegetables.
Almost every human and mechanical sound distracts me night and day often becoming intolerable, especially when mixed with other sensory feeds like mechanical and man made light interference (light off glass, metal, road glare, electrical light, etc), smell (animal musk, pollution, any kind of animal waste, bleach, perfume, meat, human skin, non-organic smoke, gas, chemicals, etc), touch (human and non-organic/un-natural fibres, sunscreen), taste (GMOs, fats, acids, chemical and mineral flavourings, polluted air, etc) and the vibration of the energy that forms everything around us.
