I know there have been several discussions on this forum about using sound on layouts (e.g. threads like these: this one
or this one
), and using sound on layouts is not always appreciated by all, especially if it's (too) loud when used on exhibitions.
Despite that, I'd like to add (diesel engine) sound to some of my layouts (both Gn15 and O9), because I think it will make those little locos appear more authentic.
My question to you is: which sounds (both engine sound and additional sounds like brakes, horns, etc.) do you think would be necessary to make a minimum gauge (diesel/petrol) loco sound convincing?
If you could choose only 3 additional sounds beside the engine sound, which ones would you pick?
Some thoughts about the hardware:
There are many on-board DCC driven sound decoders on the market, but very few have sounds that would suit the tiny locos for minimum gauge, and such locos generally haven't got enough room to fit a generous sized loudspeaker, which is what you need for decent (low frequency) sound reproduction. What I need, therefore, is a sound decoder suitable for fixed installation at the layout, that can be controlled by the analog track voltage. Furthermore, its sound should match the type of engine found in small narrow gauge locos. I'm certainly not an engine expert, but I think that a single cylinder diesel engine sound could be appropriate.
I've found and contacted a German company called LE-Elektronik
that manufactures sound modules for model railway use, and it turns out that they have some 1-cylinder engine sounds that they could program into one of their sound modules. However, I need to choose some additional sounds that can be triggered manually, such as brake sounds, coupler sounds, bells, whistles, horns, etc.
Because I have a feeling that the resulting custom sound decoder module from LE-Elektronik might be useful not just for me, but also for other members of this forum, I thought I'd post the above question, so I can make some prudent choices.
Please share your ideas and experience on this topic.
