Why do UK diesels have two tone horns?

[@KevsTrains]

They were fitted with hi and low tone horns to make sure the maximum amount of people could hear them, due to a range of human hearing abilities, some hear high times others low tones.

@@KevsTrains I'm from the US and find it fascinating that UK diesels have two tone horns while diesels here in the states have multi-chime horns. Also, what's with the Flying Scotsman's whistle? It sounds like the way a recorder sounds when you blow too hard into it.
