What causes certain people to develop tinnitus after being exposed to loud sounds?
Listening to your favorite music through headphones at high volumes is a common relaxation method but it poses potential risks to your ear health. Scientific research shows that loud sounds from music listening or heavy equipment operation at work have the ability to harm ear cells. Exposure to loud noises can result in ear damage which may produce tinnitus. Medical professionals concur that avoiding loud noises reduces your risk. Although everyone exposed to loud sounds faces potential ear damage risks, only specific individuals actually develop tinnitus. Tinnitus emerges as a medical condition with only about 50% of its cases traceable to identifiable risk factors. What factors set apart individuals who develop tinnitus from those who experience loud noises without hearing issues? Why can some people enjoy loud music without problems but others risk damaging their hearing? The major factor behind why tinnitus develops in certain individuals likely resides in genetic differences that make us all unique. The IL6 gene serves as a potential genetic bridge between tinnitus risk and loud noise exposure. The IL6 gene produces a protein that triggers inflammation. A specific IL6 gene variant predisposes certain individuals to develop tinnitus when they encounter loud workplace noise. The exact reason remains unknown yet it may result from two interacting elements. This specific IL6 variant demonstrates increased activity which results in elevated production of inflammatory proteins. Exposure to loud noise activates IL6 which results in additional inflammation. Damaged ears show elevated levels of these inflammatory markers. The combination of these two sources of inflammation could make you more likely to experience ear damage compared to people who have a less active IL6 gene. We’re all built differently. Your DNA holds information that might help identify your genetic risk for tinnitus and reveal the best methods to lead a quieter and less stressful life. The report examines the genetic factors involved in tinnitus. Read more to find out: The influence of your genes on tinnitus development alongside your genetic risk score evaluated from over 420,000 variants leads to personalized recommendations for your DNA. - Genetics is responsible for up to 40% of the variation in people's likelihood of developing tinnitus. - Factors that increase risk for tinnitus include older age, loud noise exposure, ear infections, head and neck injuries, and earwax blockage. - A high genetic risk can increase your vulnerability to risk factors such as noise exposure but wearing hearing protection may help lessen the effects of poor genetic predispositions. A low genetic risk profile does not prevent the harmful effects of intense noise exposure. Hearing ringing, buzzing, or roaring sounds in your ears happens to many people like you. A majority of individuals experience these "ghost sounds" occasionally. Constant hearing of these sounds over extended periods could indicate the presence of tinnitus. The condition known as tinnitus involves hearing noise when no external sound exists. This condition involves hearing noises that are inaudible to everyone else. Every individual experiences a unique version of this sound. The sound varies in loudness and pitch, as well as how long it lasts and where you hear it. Tinnitus manifests in two distinct forms known as subjective and objective. Tinnitus is subjective when only the affected person hears it but becomes objective when a doctor detects it using a stethoscope. Each year more than 21 million Americans endure tinnitus which means approximately one-tenth of the adult population suffers from this condition. Tinnitus typically indicates a problem exists within the inner ear structure or the auditory nerve linking the inner ear to the brain along with the brain section responsible for sound processing. Aging and noise exposure are common tinnitus triggers alongside earwax blockages and ear infections while head injuries and otosclerosis also contribute to this condition. Your doctor can assist in diagnosing and treating the root cause of your tinnitus. However, the cause sometimes can’t be found. Doctors may recommend patients use white noise machines or hearing aids and sound-masking devices in these situations. Tinnitus becomes a significant source of stress when it fails to resolve naturally. The presence of tinnitus can lead to mental health problems for some people. Patients with persistent tinnitus conditions may require treatments such as cognitive-behavioral therapy or medication. Genetic factors account for up to 40% of the likelihood that someone will develop tinnitus. Research shows that genes affecting tinnitus also control ear bone health through ANKH and regulate nerve cell communication via KCNQ4 and KCNE1 as well as KCTD12 and SLC6A4 while they also sustain nerve cell survival through ADD1 and SLC12A2 and BDNF and manage inflammation through IL6.
