128 FONIX <strong>7000</strong> Hearing Aid Analyzer 5.3.6 Viewing IEC 05 Results 1. OSPL 90 response curve 2. RESP curve measured at reference test gain with a 60 dB SPL input 3. Full-on gain (FOG) curve with a 50 dB SPL input 4. Maximum output and its frequency 5. Three frequency average of OSPL90 6. Maximum gain of the FOG curve and its frequency 7. Three frequency average of FOG curve 8. Reference test gain calculated (target) and measured (actual) Figure 5.3.6—IEC test results 9. Equivalent input noise 10. Response limit and its maximum and minimum frequencies 11. Total harmonic distortion 12. Maximum HFA magneto-acoustical sensitivity level (HFA MASL) of induction pick-up coil: three frequency average of the telecoil measurement made at full-on gain with a magnetic input of 1 mA/m 13. Equivalent test loop sensitivity (ETLS): three frequency average of the telecoil measurement made at the reference test position with a magnetic input of 31.6 mA/m.
Automated Test Sequences 129 14. Battery current drain 15. Frequencies used in three frequency average measurements 16. I/O curve(s) measured at specified frequencies (2000 Hz is always measured) 17. Attack & release measurements at specified frequencies (2000 Hz is always measured) 5.3.7 Understanding the Menu Settings The following menu settings are available in the local menu of the IEC screen. General Settings • User—FONIX user type. Beginner mode provides extra help messages and eliminates menu settings unnecessary for most users. Expert mode eliminates some help messages and adds extra menu settings. • IEC Standard—Selected version of the IEC 60118-7 standard. Choose from 1994 (IEC 94) and 2005 (IEC 05). • Noise Red (Tone)—The amount of noise reduction used in the IEC measurements. See Section 2.3.1.1for more details. • Battery Meas.—The status of the battery current measurement. Turns it ON or OFF. (Battery pill required for this measurement.) • Battery Size—The size of the battery of the hearing aid being tested. • 12 dB Dist—The status of the 12 dB harmonic distortion rule. When measuring harmonic distortion, if the amplitude of the response at the second harmonic of the frequency being measured is 12 dB greater than the amplitude of that primary frequency, the harmonic distortion measurement should be ignored at the primary frequency. Turn this rule ON or OFF. • Equiv Noise Test—Status of the EIN measurement. Turns it ON or OFF. Printer Settings • Print Label—Status of the printing label. Choose ON or OFF. • Printer—Printer used for printouts. Choose INTERNAL or EXTERNAL. See Section 2.4. AGC Settings These settings only appear when the IEC 2005 test is selected in the IEC Standard setting above. • AGC Switching—Pause during the test sequence that allows the user to change the compression setting of AGC aids according to the IEC standard. Turn ON or OFF. • AGC 250, 500, 1000, 4000—Status of the AGC measurements at the specified frequency. Turn ON or OFF the I/O and attack and release measurements at each frequency. 2000 Hz is always measured, so it is not selectable.
