Electroacoustic Evaluation of Advanced FM Systems

Please note: exam questions are subject to change.

1. The FM fitting approach recommended in the ASHA 1994 "Guidelines for Fitting and Monitoring FM Systems" has been called the: Equal gain approach Equal output approach FM Advantage approach FM Offset approach None of the above
2. The equal output approach is appropriate for fitting FM systems that will be used in the FM plus hearing-instrument mode of operation True False
3. The FM advantage approach recommended in the ASHA 2002 "Guidelines for Fitting and Monitoring FM Systems" can accurately predict true FM advantage for FM systems coupled to nonlinear hearing instruments. True False
4. The FM fitting approach recommended when coupling nonlinear hearing instruments to FM receivers with adjustable FM level has been called the: Equal gain approach Equal output approach FM Advantage approach FM Offset approach None of the above
5. The FM offset procedure recommends electroacoustic testing using which of the following input levels to the FM and hearing-instrument (HI) microphones? FM = 80 dB SPL; HI = 65 dB SPL FM = 80 dB SPL; HI = 80 dB SPL FM = 65 dB SPL; HI = 65 dB SPL FM = 86 dB SPL; HI = 80 dB SPL None of the above
