Practicing with ear plugs in ears?? Well Ladies and Gentlemen. I knew I had read this. I first read this on Curry's mouthpiece internet site. It is at the bottom of info. in the CUSTOM MOUTHPIECE section of advertisement. From reading these various articles. I realized one thing. Practicing in to small of a area with strong horns like this Conn and Olds is wreaking what little hearing I have. The ear that is ringing I have put in a ear plug. It is not hindering my playing. In fact I found what m. p.'s are really working the best. As I can hear the buzz from inside out. I will put it to a good test tomorrow. Will let my wife listen to a few pages of exercises played with and without the plugs. Some of us maybe damaging our hearing and not realizing it. Of course I will have to insist that my wife not use her ear plugs while I play.
