sound question

[SKYGUNS]

is it possible to do the following,


1) hear the hand pedal wheels on the 5inch and other AA guns

2) hear a mechanical sound when you turn a turret on a tank




quick question, is it the prop or possibly the sirens making the plane sound cool on its dive?
here's a example, watch the middle to the 3rd quarter of it http://www.youtube.com/watch?v=k-qK5gbvCXI

Its not the propeller. Its this:



This siren was attached to the left side landing gear of earl Ju-87s, in order to make a lot of noise and scare the troops and people below. Its only job was to make that really loud screaming noise as wind blew through it.
