9.5Spectral analysis in Multicurve

Selecting a stimulus level of 0 dB (off) in [Multicurve] presents a spectral analysis of the coupler microphone signal (Scale = dB SPL) or the difference between the coupler and reference microphone spectra (Scale = dB Gain).

If the stimulus type is [Pink noise], the analysis is performed in 1/12th octave bands and displayed in real time. Pressing <Continue> captures the displayed spectrum.

If the stimulus type is [Swept], a swept filter analysis is performed in 1/12th octave bands and displayed at 1/3rd octave frequencies. Pressing <Continue> causes the swept filter analysis to be performed in 1/12th octave bands and displayed at 1/12th octave frequencies.

9.6Battery drain test

The battery drain test automatically measures the battery current when there is no input signal (quiescent), when the input signal is a 1 kHz tone at 65 dB SPL and the average of the currents when the input signal is 90 dB SPL at the HFA or SPA frequencies (Avg @ 90 dB). Battery life is estimated assuming 80% quiescent and 20% Avg @ 90 dB use. Optional battery pills are required.

With the hearing instrument set as normally used:

1)Install and connect the proper battery pill. See 2.5: Battery pill use and care

2)Highlight and <PICK> Battery drain from Hearing Instrument Tests list.

3)Highlight and <PICK> [Battery type] and select from drop-down list.

4)Highlight and <PICK> [Hours per day] and select from drop- down list.

5)Highlight and <PICK> [Start test]
