Thanks for referring Destiny 1200 for me. I think it is the closest digital hearing aid compared to Beltone CSp-II analog programmable. However, I still think 1200 is about 80% of CSP-II.
Interesting, I have tried NL1*, factory default digital formula. I feel the speech is quite clear for most people except for some men, but I like to have louder sound. I also don’t like the compression, it always bothering me for some speech. However, I felt comfortable in noisy area. The kneepoint is set 44 at ch 1 & 2, 40 at ch3, 54 at ch 4, 50 at ch5 & 6, 46 at ch7 & 8. The gain is -1 at ch1, 18 at ch 2, 27 at ch3, 43 at ch4, 52 at ch5, 45 ch6, 39 25 at ch7 & 8 for soft. -14 ch1, 5 ch2 9 ch3 25 ch4, 25 ch5, 24 ch6, 23 ch8 18 ch8 for loud.
The threatre setting is basically the same gain for most ch, except high for ch 1,2 & 3. It is louder and better for men but still need more volume.
I switched to NAL-R. I felt it was louder but only the low tone. The high pitch(speech) was worse. I dumped it right away.
I also tried Berger.
For normal setting, it was not too loud and quite clear. However, the sound is not loud enough and I still like more clear speech. Maybe I need more high pitch. It works ok in quiet environment, but not in noisy place.
For the threatre/distant settings. The sound is louder and the speech is clearer. But for some people(ladies), I feel the sound is too low tone and override the high pitch. Overall, I still can hear their speech but feel the sound is too low tone and want a little bit more high pitch. For most men, I can hear very well for the speech. The kneepoint is set at default, 52 at ch1 & 2, 48 at ch3, 38 at ch4, 34 at ch5 & 6, 30 at ch 7 & 8. Gain for soft is 19 ch1, 28 ch2, 38 ch3, 45 ch4, 54 ch5, 47 ch6, 41 28 ch 7,8. Gain for loud 2 ch1, 14 ch2, 19 ch3, 26 ch4, 35 ch5, 28 ch6, 23 18 ch7, 8.
For automatic telephone, it always have feedback and barely can hear the telephone voice.
ZCT: I think either Berger or NL1* works for me. I like to have NL1* crisp speech, more comfortable in noisy environment, but Berger power, volume and no compression.
In my perfect case, I like to have Berger threatre settings but with more gain in higher pitch (clearer and crisper speech) and maybe a little bit less gain in low ch. How should I do that, adjust the kneepoint, or gain in some channels. Please advise. I appreciate your help and knowledge.
