SUBSIM Radio Room Forums - the attack periscope's sound when it's turning?

It seems that if there was any sound it would not very pronounced.

If it's a deadly silence, then you can hardly hear and motor engine.

But after reading all this and watching some movies, I've come to this conclusion:

Bot periscopes could be operated by hand, without any help for an electric motor, and maybe both periscopes or just the attack periscope could be operated with the help of an electric motor. The purpose of the electric motor could be to help giving a 360º lookout, sitting on the little chair and letting it do the rest. The scopes didn't seem to be very heavy to be turned by hand.

Conclusion... I don't think we need a sound for it.

That's pretty much the same conclusion as I was coming to. Makes one wonder if the usual periscope noises aren't a bit too "over the top" Going to keep them though - but may quieten 'em down a bit.

For anyone needing a horizontal peri movement sound there is always NYGM's clock tick. However ambient noise levels in a U-Boat could be pretty high....remember those BBC sound recordings?? ( Wouldn't mind betting they were from U 570), so I think a gauge movement would have been inaudible. Besides I seem to remember some NYGM users thought the sound was irritating and wanted to remove it.

Oh well, that's that then! You can have the rest of the weekend off :rotfl:

It seems likely that the DAS BOOT sounds were not realstic but like many things to do with U Boats, it's difficult to be sure. Soundwise there doesn't seem to be much available - the BBC recordings seem to be the only readily obtainable sounds that aren't film related. Unfortunately they don't include any peri noises.
