Very interesting idea Eric. There are also sorts of insects, birds etc that navigate by the Earths magnetic field, the moon (thats why moths fly round a candle etc) . To navigate by a sound though it would have to be a "fixed point" or a sound that stayed in the same place pretty consistently for anything to navigate by - animals, insects and birds move around a lot so it would be difficult to use them help with navigation. In the article above it shows theres some evidence birds may use very low frequencies to help with navigation which are more likely to be in the same place (tectonic plates rumbling etc) . I am researching how plants respond to sound - and it is the opinion of one biologist I worth with that hypothetically "the angle of incidence" or direction a sound comes form might affect physiological responses in plants - response so it is possible that direction plays a role there too - though this would not be related to the magnetic poles - just local sounds. There might be some relationship between light and sound direction though - ie when the sun is setting a certain bird might fly east or north etc etc
