decided to post it in field recording section as Chris Watson being the author and the host of the program.
a documentary exploring issues concerning sonic ecology, meaning of tranquility, escape from everyday human-made din, sound and silence perception, active listening etc.
two parts, each about 30 minutes long. very interesting and thought-provoking, I'd say. http://www.bbc.co.uk/radio4/science/tranquillity.shtml
the program can be streamed and listened to as an .ram file. foobar and VLC media player open this format. I'm sure other players will as well.
enjoy and feedback
