This is fascinating. It could be an artifact of the radio's design, or... Could we possibly be seeing a process here in which the dynamic range of the human ear/wetware is being increased by lowering the amplitude range of the input? Maybe mammalian ears evolved to work better (i.e., more discrimminatingly) at lower volume levels... This might make sense in evolutionary terms, when you come to think about it.
