Sorry, but 98db is just bonkers. That's nearly 8 times as loud as the conventional yardstick of 'acceptable' noise level (70db). You're well into the range of hearing damage when subjected to these kinds of levels for more than a couple of hours without protection.
There's no other way to put it, it's properly anti-social. Is it any wonder that public opinion has turned against 'petrol heads' if they are subjected to this kind of noise?
