For me, the most interesting report related to a sound engineer, Professor Paul Moore, who has recorded the sound of Ballinderry River, using sensors floating on top of the water, and converted these recordings to a song, or music, in order to give the river a voice – “a soundscape, as well as a landscape”. It is startling: the usual gurgling sounds, but with a haunting backdrop, almost like whale song, which Professor Moore referred to as the Ban Sidhe of the river. It certainly got my attention; I was in awe.
I wish I could get a copy of some of the recordings, but, alas, I have to make do with the snippet broadcast on the podcast. They are endeavouring to expand their recordings to other rivers, and recording the individual songs.
