4.2.4 Viewing the results
See Figure 4.2.4 for an example of an ANSI 96 test sequence (including the telecoil measurement).
1. OSPL90: Output measurement at 90 dB SPL
2. RESP50 (or 60): Response measurement at 50 (or 60) db SPL at reference test gain
3. SPLITS: Telecoil response curve measurement
4. NR: Noise reduction used in tests
5. SPA/HFA: Frequencies used for the three frequency average
6. MAX: Maximum frequency response measured and the frequency at which it occurred
7. SPA/HFA OSPL90: Three frequency average of the OSPL90 curve
8. SPA/HFA FOG: Three frequency average of a full-on gain measurement at 50 (or 60) dB SPL
9. REFTG TARGET and MEASURED: The calculated reference test gain and the actual measured
reference test gain
10. EQ INP NOISE: Equivalent input noise
11. RESP LIMIT and F1 and F2: The response limit level and the two frequencies where the
response curve crossed over this level
12. THD: The total harmonic distortion measurements
13. HFA-SPLITS: The three frequency average of the telecoil SPLITS curve
14. STS-SPLITS: The difference between the high frequency average of the response curve and
the SPLITS curve
15. BATTERY: Battery current drain
16. I/O CURVES: Input/output measurements at up to five different frequencies
