I'm in my early 60's and understand that with age comes a decline in hearing with respect to upper frequencies. So my question is whether or not the upgrade to RAAL would be an advantage over the NrT, i.e., assuming my upper limit is 17 khz what would I be missing in the presentation of the NrT vs the RAAL. I've read a lot about the harmonics of the RAAL, with the term "airy" and "lingers" used quite a bit. But are those things we can still hear as we get older? I don't expect either one to be "harsh" or overly "clinical" based on what I've read which is good because that would be my primary concern. I know there's been a lot of debate about the characteristics of both and I am not looking for a "which one is best" response. Just any thoughts on whether or not I should even be concerned. Appreciate any feedback provided. And apologies if already asked and answered.
