This proposal contains the description for a hearing protection device (HPD) fit-test instrument, the CCA-200fit. The CCA-200fit has the capability to determine if an individual is receiving effective noise protection from an HPD. The CCA-200fit also has training capabilities via a display, audio, and a touchscreen which will allow it to provide instruction, feedback, and results to the individual being tested. The instructions will be provided in the subject?s own language. A REAT (Real Ear At Threshold) fit testing algorithm utilizing either deep cavity headset or free field speaker will be used which will allow a fit-test to be conducted on a wide range of HPDs. The CCA-200 fit will be capable of both a highly automated mode that will test up to ten individuals at once and a highly interactive mode that will test a single individual. It will also have many additional features such as SQL Server database, reporting capabilities, import/export, SQL generation capabilities, and etcetera. Database capabilities include the ability to view, modify, sort, select, print, backup, restore records related to tables that contain subject, audiogram, fit-test, user-defined, company, and etcetera information.
