Doesn’t the complainant just have tinnitus?
Not usually. Tinnitus is a ringing noise in the ears and in some ways its effects are similar to LFN. However, studies have found that most LFN sufferers do not have tinnitus, or if they do that they can hear the LFN separately to the tinnitus. So tinnitus and LFN are separate phenomena and tinnitus cannot explain the majority of cases of LFN.
