I am thinking if and how it is possible to make a project like this:
a higher than a certain lever of sound goes into a mic or other component.
Arduino recognizes high level and instantly plays a pre-recorded message through a speaker
(or if it is very very hard\time consuming then just playing any sound like alarm or anything)
from what I've found out after I've searched I figure the issue might be in the part of the recognition,
the speed it "hears" the environment and telling between peak sounds VS loud noise etc' ..
That it why I am asking here,
I will be glad if anyone could point me to a simple (more like of some soldering, some programming and "plug and play") solution (if exists)
and not electronics mathematical equations please
I seem to remember a recent thread about using Arduino to drive a graphic equaliser display, and that would give you the logic you need to detect the incoming sound level. I don't know whether you want to detect any particular type of sound or just trigger on a general 'loudness' - I suppose it would be possible to add an external band filter if you want to only detect sound in a particular frequency range. There is a shield which can be used to play pre-recorded samples, forget the supplier but it's been mentioned here in the past and I'm sure a Google search for Arduino sound shield would locate it for you.
