Dear Ian Simpson (architect),

Why does the Beetham Tower hum?

The problem is caused by the glass and metal sculpture at the top of the building. When the wind rushes past the edge of the glass panes turbulence is created. This is very similar to how turbulence generates sound within a recorder. Inside the recorder there is an edge called the fipple, which breaks up the air flow when a musician blows into the mouthpiece.
