I have come to that time in life when I have trouble hearing through the background level. This is causing me problems when playing in sessions or jams (or in bars). I cannot hear myself which is fatal for me on my 56 key EC. I hoped that an Android app might allow me to clip my cell phone to my belt as a hearing aid but all those I have tried had significant sound delay.
I wonder if there might be any dedicated devices that are alternative options? Perhaps some sort of amplifier (hearing aid) that I could plug earbuds into with a volume control. Clipped to the shirt or the belt it would be near to the reeds whether standing and sitting. As most earbuds don't have a lot of sound isolation perhaps I could hear the other musicians and adjust the volume of my own instrument. I'm afraid that scheme that would have to be attempted to predict how all those variables shake out.
Any advice on a more sane solution, or general comment, would be appreciated. ?
