Now that the responses to this thread have petered out, maybe it's time to take a look at the results. The proportion of respondents reporting chronic tinnitus seems to have stabilized at about 27%, and this is not far from the average in the general population. Estimates that I've seen range from 10 - 30%, with 15 - 20% being the most common values quoted. The proportion rises in older populations, as you would expect.
As I mentioned in my first post, chances are that people who have the condition will be more likely to respond than people who don't; so a result slightly greater than the average of the population is perfectly reasonable in an unscientific survey like this.
So, to whatever extent this little poll is representative, people are neither strongly encouraged to study audio nor discouraged from it by tinnitus!
I've tried using the concentration techniques of tigre and paranoos to make my tinnitus disappear -- sadly, it doesn't work for me. Concentrating on the sound just makes it stronger and acquaints me more intimately with its details.
