We had a musical/medical lecture series run by the University 2 years ago. Doctors and Musicians formed a panel. Each evening for 6 they had a subject (one was Beethoven). The wife and I made 4 of the series.

It was interesting to note that they thought that like many deaf people, who hear nothing then when you raise your voice say 'you don't need to yell', he probably couldn't hear at normal levels, but near the orchestra his hearing returned. Very common.

As to low frequencies the challenge is to overcome the tinnitus in 2 frequencies that mess up even the nicest summer day.

On the other hand I don't hear the alarm clock (LOL), the microwave, the smoke alarm the crickets etc.

Good luck Ian, make a good case. I see TC-Helicon has a lot of new products in the low end you stick on the mic and use your guitar to control, maybe one of those is for you.
