Active-Passive noise cancellation
I bought a pair of Sony ear bud ANC headphones and found that while they reduced aircraft noise my tinnitus became significantly louder. Apparently this is due to the tinnitus being a portion of "signal to noise". If the noise is removed the SN part with tinnitus increases.
I gave up on the ANC part and used them for passive listening to music on the Powerbook!
