Hi Audionewbi, who's your favorite living sarodiya? I like Brij Narayan, he is excellent.
For the issues of hearing protection on the stage, you actually have it backwards. Musicians tend to turn up their monitors to hear/feel the bass against the background roar. A vented dynamic driver bass, which has air moving for a real bass energy, allows the musician to have this bass feel at a lower overall volume. That means the treble, which is where hearing loss and hearing fatigue tends to most often occur, is also lower.
Interestingly, isolation alone doesn't seem to lead musicians to turn down their volume, although it's part of the picture.
These points come from my discussions with ciems manufacturers who focus on building ciems for stage use.
An armature custom with spikes at 5khz for fatigue and damage and bass that lacks the moving air of real bass energy-leading musicians to turn up the volume to try to get what they are missing is a recipe for hearing damage. That's part of the reason why the new jh13fp, for example, which is being reviewed as even brighter than its predecessor, may be well reviewed by brightness loving audiophiles, but is possibly a big mistake for a stage musician. This is only some informed speculation, of course.
It's interesting.
