Re: [ST] ear plugs and autocom?

[Erik Miner <Axeis@xxxxxxxxxxxxxx>]

Thom: I have experimented with a lot of setups. First off the Autocom 
is by far the best intercom. It works, is easy to install, and 
putting the speakers in the helmet is easy and doesn't require 
cutting the liner up or any BS. Now as for volume. None of the in 
helmet speakers I've used, Autocom, J&M, Bass Monsters really sound 
very good through ear plugs. They sound fine in a demo but on the 
road it's another story, Now one can modify foam ear plugs to get 
more sound through but then one also gets more road noise :-(  There 
are also musicians ear plugs that attenuate say only 15 db. The 
problem is a simple one. In order to get good quality of sound in a 
helmet you need to really crank it up. Problem there is that one is 
trying to over come road/wind noise. The Autocom systems don't really 
amplify the audio they just pass the output from the CD , MiniDisc, 
MP-3 or what ever and none of these put out much wattage. Usually 
about 5mw per channel.

The best solution I've found for music is in ear monitors. Eric S. 
mention Precision Sound they make good ones as do several others, in 
fact one can spend over $500.00 on just the speakers alone. There are 
several very high end systems for professional recording studio 
applications and on stage monitoring. Anyway after much 
experimentation I use an Autocom for hearing my Valentine One.  And 
for tunes I use a Sony MiniDisc player with a set of Westone custom 
ear molds with the Shure E1 monitors built in. The nice thing about 
custom ear molds is that they offer about a 30 NRR rating so that one 
hears great audio and the ear molds block out road noise. In other 
words you can set a reasonable volume level before taking off and 
don't need to crank it up to hear it once you're moving. With the ear 
molds in I can still hear the Valentine go off, so I guess that you 
could also hear the intercom.

HTH,

Erik
