It is quite possible to get tinnitus with low frequency exposure. I got mine from exposure to loud music while using earplugs that basically had no attenuation on low freq.

Leaving the club the silence outside sounded like my head was inside a slowly cooking porridge kettle. This disappeared in a couple of hours. Low frequency tinnitus appeared years later. I thougt first that my neighbourg must have installed a new air condition unit.
