It's a sign of the times. Years back when people were flying Shacks/Nimrods/SHARs or any number of other noisy beasts, society was not a litigious one. Now, sadly, it is. An expert somewhere has decreed that the Tutor is too noisy for prolonged exposure (it's the same for the Hawk T1 rear cockpit), so to prevent the litigation when someone blames their hearing loss on flying said aircraft, they are changing the way it is operated to mitigate the risk.
Whether we agree or not, it's not the same world as it was even 10 years ago - we have to live with that and work around the problems. IMO, life would be simpler (and cheaper) if people accepted that things they choose to do are not risk free - but that's never going to happen these days...
