- "Listening to tailor-made notched music reduces tinnitus loudness and tinnitus-related auditory cortex activity",
Hidehiko Okamotoa, Henning Strackea, Wolfgang Stollb, and Christo Panteva,
Proceedings US National Academy of Sciences,
vol. 17, no. 3, pp. 1207-1210, 2010.
- Proposed treatment for tinnitus (a.k.a. "ringing of the ears") alters
participants' favorite music to remove an octave of frequencies
around the tinnitus frequency fc.
- After 12 months of listening to the filtered music, patients reported
lessening of tinnitus symptoms.
- Application of a bandstop filter with stopband frequencies
from (2/3) fc to (4/3) fc to cover the octave of frequencies.
- Basis for filter design question on
