After deep consideration and consultation with my mentors I have narrowed this down to............................tinnitus.
Tinnitus:- Perceived in one or both ears or in the head. It is usually described as a ringing noise, but in some it takes the form of a high pitched whining, buzzing, hissing, humming, or whistling sound, or as ticking, clicking, roaring, "crickets" or "locusts", tunes, songs, or beeping.[3] It has also been described as a "whooshing" sound, as of wind or waves.[4]
