That isn't hyperacusis though. I am currently extremely disturbed if I hear anybody even vaguely sounding like they are arguing or swearing. Even just hearing guys outside in the parking lot using plain bad language as a habit makes me upset. While I don't like the language and never have, it never used to upset me like it does now. Now, even the slightest indication that something bad might be going on is extremely upsetting. I don't even like hearing sirens going anywhere in town. This has to settle down or I will have to move into the wilderness and become a hermit. I wouldn't mind that much though. Taking long canoe trips deep into the wilderness has always been my favourite vacation pastime. Of course that way they could never call me from the office and say "Hey, Evan, we have just one little job that has to get done today..." while I was on vacation.
But the above isn't a hyperacusis response. When that happens there is no mistaking it. That response hits within a split second after the sound, about the time it takes for a ordinary reflex to take place. It is not connected to any analysis by the brain of the sound content, such as what is being said by people. Hyperacusis, from the little they know about it, is something to do with the central nervous system that does not involve the actual "listening" to the sound. It somehow activates parts of the brain such as the hypothalmus, the primary endocrine and neurotransmitter control centre of the brain. Also, without question, hyperacusis instantly causes a strong release of norepinephrine (noradrenalin, same thing). In that way it is the same as a strong anxiety response but it hits immediately without any need for your anterior cortex (thinking part) to analyse anything.
When hyperacusis hits you realise what has happened after the fact, not during or before.
