Data acquisition: VAS sheets will be completed during the initial Phase II baseline visit and 6 sets of time/dated sheets (one for loudness, one for annoyance, plus two spare sheets) will be sent home with subjects. Equivalent sets of the THI, TFI and MOCI will be included with the VAS sheets and subjects given instruction (verbally and in writing) on how to complete and return all data sheets in self-addressed stamped envelopes. Sheet acquisition will follow the course that it did in Phase I, however, they will only be collected monthly instead of weekly. The subject will return to the clinic after 24 weeks for testing including VAS, THI, TFI and MOCI evaluations. At that time they will receive their supply of capsules (medication or placebo) and new sets of VAS, THI and MOCI sheets and mailing envelopes for the second period of Phase II (Figure 1, period 5).
