Re: [ST] db's and ears



Dan , ( and anyone else using this system ),
   
  I cant comment on the placement or quality of the mic, but if they are separate units from the speakers, you should be able to run a pair of the sealed earplug style earphones with this setup. It should just be plug and play.

Dan,
Thought I'd chime in on this... as I have limited
experience with it. We've attempted to utilize the
interaurals in the fire service, specifically for haz
mat as it sounded like a good idea to have an absolute
minimum of stuff to wear before getting into an
encapsulating suit. The only problem was that they
just didn't work. The idea sounds great, but it did
not work as the quality of the produced sound was
almost unintelligible, (too muffled). I don't
remember what brand it was, but it was the best money
could buy 10 years ago. Maybe the technology has
improved since then?

I will say that the autocom system I now use is
phenomenal. They have this technology down pat. 
Noise cancelling mics are the only way to go. As a
matter of fact, we use noise cancelling mics
(Motorola) on our fire apparatus now. The clarity is
actually better from a noise cancelling mic standing
next to a 1500 gpm sutphen pumper (2 stroke diesel)
running at full throttle than it is from a standard
radio mic without the noise cancelling feature with no
ambient noise. Don't know how they do it, but it
works.

I'm glad to hear some input from practical experience. I kind of
wondered about the clarity of the interaural mics, but had no experience
one way or another.

In the field of communicators, yes, the noise cancelling mics are the
best. I went with the Starcom setup over the Autocom mainly because of
price. The downside I see to it, and any helmet mounted setup is that
you have to connect your helmet to the setup, no matter what system you
run. Also, most of the guys are looking for a mic/phones setup that
they can plug straight into a radio, bypassing the need for the
expensive communicator.

I haven't actually tried the Autocom systems, so here is my take on the
Starcom1:

It's a good system overall. Plenty of volume, clear stereo sound
(Motocomm's version doesn't have stereo, Autocom does). The mics pick
up well and are fairly clear at all speeds (tested up to indicated 135,
shh).

The problems I have with the setup, and this may be common to all, is
figuring out placement of the mic and speakers. I've played with the
mic placement on my helmet and it seems to be ok, but my wife's picks up
wind noise when we get above about 50mph. The thing that makes placing
the mic difficult on the Starcom is the lack of sidetones (the one
benefit of Autocom, and would have changed my mind if I had realized the
importance of it). The newer Starcom units have sidetones, and I may
see if they can retrofit mine. Without the sidetones, you can't figure
out if the mic is in the proper place, and my wife is apparently not as
picky as I am about the sound...

Long story short, you need to field test any comm unit before you
buy...
