SIREN SOUNDS FINE
Is it NOT a Federal Q siren?
X-ecuter is electronic, is it not? All Whelen is electronic?
Many peak the Q and keep it there.
Bad for electrical system because it draws many amps; 100 to start up.
Q is meant to coast to relieve electrical load on system.
Also, peaked may be a frequency where someone is deaf.
Or it may not be recognized as a siren:
A peaked Q matched the key of music we.re listening to, so we didn't notice it.
Another time we thought we heard brake squeal from a truck.
It was Denver Fire with Q peaked.
Another time we thought a leaf blower. Again, a Q to the max.
Rising and falling through the sound frequency spectrum is what makes the siren more effective and stand out.
Is the recording oversaturated by sound levels,
or distorted by this system upload or download?
Thanks for the interesting videos.
We videotape all of our emergent trips with a dash-mouted JVC
miniDV camcorder.
If there is ever an accident, hopefully we will have a document
of it.
If MY fault, "What camcorder?"! (Actually, I would not have to show my videotape in court if it incriminates me.)
the video also provides response times and I use it for self-critique and teaching emergency vehicle driving. (Nothing like showing your own mistakes to feel humbled!)
A friend says I should put some of our morexciting footage on My Space,
but I don't know how.
Your instruction would be welcome.
Thank you,
