When I meditate I hear all type of noises.
Birds, aeroplanes (I can see the runway from my lounge), car slamming doors, school nearby, car acceleration,tuck engine braking, just to name a few.
I just observe how my attention is shifting from one object to another (mind and body)
I never thought it is a hindrance to my meditation.
I try to stay (flow) in the present moment with knowledge without attachment and aversion.
