I don't hear mine with an ambient noise of a switch buzzing or when I'm standing in the lobby at work with traffic sounds in the distnace but then sometimes I can hear it with the tv on a moderate level and louder than an ambient noise, very weird

Yes. My theory is that the acoustic properties of a space can induce resonant effects on the auditory system, *likely* through variance in the Eustachian tubes. i.e. ETD (perhaps mild) may play a role in the phenomena.
I find that rooms; I think due to the sharp geometric edges, reflect sound waves in a very unnatural manner which can aggrevate my reactive T more than being outside where all the acoustic reflections are from natural curves.
Do loudspeakers (TV, music, phone) affect your T?
