associate all ear pain in hyperacusis patients to TTTS. These researchers suspect that a reduction in anxiety and the desire to protect one’s ears from sound can reduce TTTS symptoms. The audiologist Myriam Westcott has led several publications on Acoustic Shock Disorder (ASD) and development of TTTS in hyperacusis and tinnitus patients. These studies provide an interesting perspective on several hyperacusis symptoms (referred to as TTTS symptoms in these studies) that are shared by others who do not have hyperacusis. These researchers suspect that TTTS symptoms develop due to unusual hyperactivity in signals sent from the brain to the middle ear muscles to protect the ears from sound. Some researchers refer to this set of symptoms as Tonic Tensor Tympani Syndrome (TTTS). The more severe the hyperacusis the more likely other symptoms from this list will develop. Sharp, Dull, or Burning Pain (Hypothetical Direct and Indirect Mechanisms)Īural fullness occurs in the majority of cases and is one of the more uncomfortable symptoms that arises when hyperacusis develops.Muffled and/or distorted hearing (When hearing tests are normal).Alterations in ventilation of middle ear cavity (Open Eustachian Tube).Autophony: Boomy or echoey sound from voice (Open Eustachian Tube or conductive hyperacusis).Aural Fullness (Closed Eustachian Tube, contracted tensor tympani, or inner ear pressure). The following symptoms can occur at the onset of hyperacusis. Non-acoustic Contraction of Middle Ear Muscles Tonic Tensor Tympani Syndrome (TTTS)
