TRANSCRIPT: 

I would like to talk with you about a medical disorder that is incredibly common, and yet it gets often underestimated – misunderestimated, as one of our former presidents would have said – in its impact on our psychology and on the patients. The patients really suffer from it.

And it’s very pervasive; about 50 million Americans suffer from it. I bet many of you in the audience will have friends or family that suffer from it.

What I’m talking about is tinnitus, the ringing in the ears. It’s often depicted in this painting by Edvard Munch although we don’t know for sure whether he actually had tinnitus himself. But the person in the painting is sort of covering his or her ears, and it doesn’t help because the ringing is actually generated in the brain.

It’s not a real sound that, that a person hears; it’s a phantom sound. So we often talk about it as ringing in the brain rather than ringing in the ears.

And of those 50 million Americans that suffer from it, about 10 million of them really suffer very badly – they go to the extent that they have depression and suicidal thoughts. And I get emails every day from patients that are asking, “Is there not a cure?” There is no cure, unfortunately, at this point. And part of our research is aiming for that, of course, that we’re trying to find ways to help these patients.

And I can play some examples for you, (high-pitched tone) of what that sounds like. This is just a pure tone of a single frequency, relatively rare. Usually, tinnitus sounds more like the next one… (hissing sound). You can imagine how annoying that is. If you hear that all the time in one of your ears or both of your ears. You can’t turn it off, you can’t run away from it; it’s always there.

(cricket sound) Sometimes, you get this more sophisticated cricket sound that you hear. So, people suffer from it. There are groups that are more affected or at risk than others. Musicians get it surprisingly often because they are exposed to louder sounds than they realize. I once remember being at the Kennedy Center in Washington, DC, where we live, and went to a concert there, symphony concert by the National Symphony. They played Shostakovich’s War Symphony. Very loud, of course.

One of the violinists in the first or the second row was sitting right in front of the trombones behind her. The trombone was sort of blowing right into her ear and she was reflexively covering her ears to protect herself.

This is actually the right reaction, just to avoid loud noises in order to avoid getting hair cell damage, and then hearing loss, and ultimately tinnitus.

So, loud noise exposure is certainly one of the biggest risks. And then you take a group like construction workers. If they don’t wear hearing protection, that can be very risky. The group most at risk are our war veterans, of course. They are constantly exposed to artillery fire, to bombs, explosives and so on, you know.

In addition – this is a very important factor, which I want to stress in this presentation – stress is a very important factor. So, it’s not just the loud noise exposure that can give you tinnitus – it actually doesn’t always do that – but if it combines with a stressful situation, this is the most likely scenario where you end up getting tinnitus.

So, our veterans are much more likely to come home from the battlefield with tinnitus. In fact, the Veterans’ Administration, if you look up the statistics, they show that tinnitus is the most frequent cause for benefits paid to veterans. Hearing loss is the second most frequent one.
