Hello, I am an Audiologist, and I have also had ringing tinnitus my whole life. I remember being put down for naps as a very young child and laying there listening to the ringing in my ears and watching the floaters in my eyes move across the white ceiling. I assumed everyone had it, until I first took a Speech & Hearing course in college. Ever since then, I’ve wondered what silence sounds like.
Loud sound damages the microscopic hair cells in the ear where sound is transferred from a mechanical vibration to an neuro-electrical signal. The numbers of these hair cells are so great that we can sustain some damage but maintain normal hearing sensitivity. So if you go to a loud rock concert, your ears might ring for a day and the hearing may seem slightly muffled, and it progressively returns to what you perceive as normal; however, the damage that was done is permanent. To simplify, say you have 10,000 hair cells and you’ve destroyed 100… you will still be able to hear normally, but now you only have 9,900 hair cells. The next time you do similar damage, there will be 9,800… etc. These numbers are arbitray, but I am using them to show that the effects of noise damage to the ears is cumulative.
Also, we need to be mindful that it is not just how loud the sound is, but also how long we’re exposed to it. People who work construction or around machinery are required to use hearing protection. However, things that don’t cause noise damage to the casual user (e.g. vacuum cleaners, hair dryers, sewing machines, dental drills) can do damage from prolonged exposure to those who use them in their work.
In addition, some people’s ears are more resilient than others, whether through genetic factors or other health influences. People with high blood pressure or diabetes are at greater risk for hearing loss and tinnitus. As are those who smoke. Certain medications can be damaging to the ears, as well – and again there seem to be different sensitivities among individuals.
Typically, noise-induced hearing loss and tinnitus are fairly equal in both ears; as is the case with loss and tinnitus from aging or associated medical causes. Asymmetrical hearing loss or tinnitus, as @ers2007 reports, is atypical and should be checked by a physician.
@ers2007: “Water pills” is what most people use to describe diuretics – a class of medications used to reduce fluids in the body that cause swelling. That is very different from the fluid that can build up behind the eardrum, which is usually treated with antibiotics and/or decongestants. There is a specific condition, Meniere’s Disease, that can cause unilateral tinnitus, but also has hearing loss and vertigo (spinning dizziness) associated with it. Some people’s symptoms are improved with low sodium diets and some take ‘water pills’ as well as they effect potassium levels. I am just curious about your case because from your limited details it doesn’t quite add up.
As @ers2007 also noted, many people find relief from their tinnitus by “masking” it – meaning using other sounds to distract from it. For years, I also ran a fan at night. Now I use a noisemaker that plays the sounds of the rainforest. There are several options for that… mine is an iPhone App. The masking phenomenon is also why most people complain that their tinnitus seems louder at night – it isn’t… the world and your mind are just quieter, so the noise in your head is louder on relative terms.
Custom fit maskers and hearing aids are available. There are also therapies that use progressive sound levels to retrain the patient to ignore the tinnitus more effectively.
Some people find relief when taking gingko biloba supplements, and that is the only substance that has been independently proven to bring tinnitus relief to a significant number of people. However, ginko biloba is a blood thinner, so people should check with their physicians and pharmacists prior to starting a ginko biloba (or any supplimental) regimen. Also, dietary supplements are NOT regulated, so you can not know if what is in the bottle is what is on the label. ‘Arches Tinnitus Formula’ was developed by an ENT Doctor, and they claim to maintain stringent standards so the dosage will be consistent. Consistency is the key… this is an ongoing therapy that must be maintained on a very regular basis to provide consistent relief.
Not every treatment works for every patient. There are so many variables that influence how each person deals with their symptoms. The degree of hearing loss (if any) associated with the tinnitus is a major factor. A comprehensive Audiological evaluation should be performed on anyone who is complaining of tinnitus – especially before beginning any treatment.
