The real problem with model sounds is that you can't fit a huge speaker to reproduce the low tones. So they don't sound right.

Today there are already excellent small speakers from mobile phones - some of them are delivered with optimized cabinet to get the maximum efficiency.

Maybe I am just too picky about sound, but even the best small speakers just sound tinny and weak, if you stand back and listen objectively. A friend has an O scale layout, the sound in those locos is a world better than any HO. But still, real railroads have a lot of very low rumble frequencies. There's fundamentally no way to reproduce that sound with a tiny speaker.

If you want BIG sound, forget about on board sound...

HI Bernd,

Did you widen the gap or narrow it?

In our scale 1 club we finaly prohibited all sound locomotives, the noise was extremely disturbing and loud ( some of the locos have 10 W amps on board) :grin:
Therefore I edit sounds for my friend, who has a small modelltrain service workshop, but I do not have any locomotive with sound on board. I prefer a noise free layout, where I can hear the noise of wheels jumping over the gaps in rails. :thumbup:

I operate on a large H0 layout, with 80-90 locos, most in triple lash-ups, and all with sound. The owner does not skimp on money, but I don't find the sound adds to my enjoyment.
For my own layout, I will forget about sound decoders. Think of all the money that saves!
Otoh (=on the other hand, for non-native English readers), the Stationary Sound idea above, or Soundtraxx's Surroundtraxx, where the sound travels progresssively to various stationary speakers as the loco moves, is another story entirely...

Hi Gerhard

I fully agree with you! I do not mind to have ocassionally a good railway sound ambient, and also do not mind when some of the locos move on the layout with sound, but I do not think that it is acceptable on long term basis. Most the layouts ( and layout rooms) are anyway quite noisy, do we need to pollute our hobby environment with additional noise?

:shock:

( i spent over 15 years on diverse rock stages.... :grin: ..)
