Audio Monitor

[GregOConnor]

David, I know that this forum category is your blog but wanted to start you on an idea I keep coming back to.
I was reviewing 5 ton trucks at auction for my gijeep.com site and ended up buying a bunch of recoding equipment. cant call it high tec because I bet there are phone apps that can do the same listening and making a graphical or digital file of sound.

My idea is to build a listening device for the bus engine compartment and the towe'd cabin and tow'ed engine compartment. that device makes a record of the sounds in real time and compares the sounds to a file proven to be recorded during normal operation. All done in real time so the operator can puhs the equipment to the limit and back off or stop when issues arise.

Temp gauges we now use are much like a audio graphical display would be. Idiot lights we now use compare input to a normal threshold and are much like a display warning of abnormal sound would be.

sitting in my tractor I can hear issues and some of the sounds are even enhanced when I use ear phones which makes me wonder if there are clues that I miss by not being able to hear all the noise and being able to remember all that is normal.

back on Ernie's forum around 2006 there was a poster looking for a audio file of an 8v92. That got me wondering why he needed it. I think he was just nuts about sound? maybe not.
