Abstract:
1. A method of optimizing an earpiece, the method comprising the steps of: a) characterizing a driver corresponding to the earpiece, wherein an initial driver response is the result of said characterizing step; b) boring a control port into said driver, wherein said control port has a cross-sectional area, and wherein said cross-sectional area resulting from boring step b) is less than 25 percent of a cross-sectional area corresponding to an output port of said driver; c) re-characterizing said driver, wherein a step c) driver response is the result of re-characterizing step c); d) comparing said initial driver response and said step c) driver response to a target driver response; e) performing step f) if said step c) driver response is closer to said target driver response than said initial driver response is close to said target driver response; f) increasing said cross-sectional area of said control port, wherein said cross-sectional area resulting from increasing step f) is less than 25 percent of said cross-sectional area corresponding to said output port of said driver; g) re-characterizing said driver, wherein a step g) driver response is the result of re-characterizing step g); h) comparing said step g) driver response and a previous driver response to said target response, wherein said previous driver response corresponds to a response of said driver with said cross-sectional area of said control port prior to performing step f); i) repeating steps f) through h) if said step g) driver response is closer to said target driver response than said previous driver response is close to said target driver response; and j) ending said earpiece optimizing method if said previous driver response is closer to said target driver response than said step g) driver response is close to said target driver response.
