If you want to hear what a diaphone sounds like, try
www.pipechat.org/archives/1998/november/digest603.html
and
http://diaphone.tripod.com/diaphone_sounds.htm (Gamewell diaphone - smaller units but some interesting info)
.
Lighthouses are one of my interests along with WW1 rotary aircraft engines. I reckon the engines are noisier than the foghorns.

The Diaphone Fog Signal
Seeing the Light
<<Interesting use of piping and air pressure: Diaphones were a once familiar sound heard throughout the Great Lakes from the early 1920s until the late 1960s / early 1970s when most lighthouses were automated.>>
