Here is the problem: At my work I am required to use 2 way radios to comunicate with the rest of my team. The first problem is I work around vehicles and equipment that is noisy to say the least. I have used an ear bud to enable me to hear the communications, however there are some loud talkers on our channel that deffen me when they transmit.
I am wondering if there is an inline limiter available or one that I could make that would limit the max decibels of the loud transitions and allow the normal ones to continue.
I would be looking for a unit with an adjustable max allowable volume, it would need to be small, work off existing voltage, and most importantly the limiter would have to not cut out the loud transmitions but dampen (not sure if that is the correct word) them alowing them to be heard at the same volume as the normal transmitions.
Any help would be appreciated
Thanks Mike

Something as simple as a pair of germanium diodes plus a few resistors might work. If 0.3V p-p is still too loud, use an inline volume control or fixed resistors between the clipper and the 'phones.
Check out ham radio DIY sites, and suppliers of communications gear.
Maybe a guitar stomp box compressor could be adapted. Or, build a compressor/limiter from scratch using a chip from THAT.
It wouldn't surprise me if there's a headphone amplifier chip out there that includes some AGC/limiting features.
If you google for headphone amp with limiter, you'll find a bunch of relevant discussions.
