I am new to this forum and being not very electronically savvy I was hoping with all of the experience out there someone could help me with my project. I spend a lot of time on tractors mowing and brush-hogging fields and given the noise of the diesel engine and the mower deck I always wear ear protection. I also like to listen to audio-books during this somewhat mind-numbing work and presently use custom molded ear inserts with transducers that I also use in my race car. The ear molds alone are not enough to protect my ears from the noise from the tractor so I also use a set of muffs over them. The problem is that after many hours on the tractor my ear canals become quite uncomfortable.
So I thought I would make a headset using a comfortable, industrial type earmuffs ( Howard Leight, Leightning Thunder T3 : NRR=30) into which I inserted a set of old Sony Walkman type speakers (24 Ohm impedance). These work great at low noise levels but at higher levels, when the tractor is at mowing rpm, I cannot quite hear the audio-book despite turning up the MP3 volume to the maximum setting. I am playing the audio-books on a Creative ZEN Mosaic EZ100 MP3 player. I could not find any specs on the output of the MP3, but I do have the ability to limit the volume on this player and have made sure that it is set to the max. I suspect that I need speakers of a different impedance...presumably something under 24 Ohm. Of course, I do have the ability to turn down the volume setting on the MP3. I also assume that these speakers, as with most out there, are designed such that you cannot make the music that they normally play too loud. I think I read somewhere that they are limited to 82dB given the output of the normal Walkman, iPod, MP3 , etc.
Any recommendations for speakers that would get the job done?
