@Telis - I think you are correct that severe T of the type which can be heard above almost any level of external sound is a different phenomenon to minor T and present a different magnitude of problem to those who suffer from it. But I think you are wrong to criticise other people who offer well-intentioned advice, just because you don't see their advice as being applicable to your own situation. The advice given by @Neo5500lp may be helpful to someone else. If you don't consider it to be relevant to your own case, then just ignore it. There is no need to insult the guy. It is a support forum and we are supposed to be trying to help each other.
