Not so sure about that to be honest, this is only for healthy ears. Once your cochlea has been damage it get much more vulnerable. Some people with T and H get permanent increase of T, permanent or temporary hearing loss from lower durations.
Plus it has been shown that damage to the cochlea happens at lower volume and shorter duration, but the damage are not to the hair cells but to the synapses, which may be responsible for T and H.
So yeah if you have T don't stay in a 100db area even for less than 15 minutes

I have never read anything about "unhealthy" cochleas being less resistant to sound pressure, nor anything about the qualitative difference between natural aging cell death and sound-induced cell death, or drug-induced cell death. I suppose a death is a death (a dead hair cell, synapse, or whatever), and anyway, what are important are the still living cells, so from this point of view, there is no difference in sound resistance. But probably you have another information?
Everyone has "damaged" cochleas. If we follow your logic, everyone would be deaf, and would have tinnitus and "hyperacusis", as you call it.
The onset or worsening of tinnitus in people with "hyperacusis" has nothing to do with cochlear damage. These cases, precisely, are interesting to study the true causes of tinnitus. I don't know if cochlear damage has something to do with the possible chronicity of the tinnitus, I am talking about the onset (or worsening) itself.
It is not the first time that I read in forums references to the so-called "hidden hearing loss" as an important factor for explaining sound intolerance. I find this incredible, especially because what is written about it is meaningless.
The idea of a fragile cochlea is perfect as an alibi for phonophobic people. What is a bit "fragile" and uncomfortable, and sometimes painful, is a tensed tensor tympani mechanism. The level of intolerance is proportional to the level of tension/displacement/abnormality of this mechanism. Overlapping "hyperacusis" and "ttts" is beyond surreal.
