A New Advancement When It Comes To Hearing Loss Prevention And Cure
Studies involving lab animals are being undertaken by scientists for many years now
in order to determine the possibility of a pill to lessen the harmful effects of noise to hearing. But this time, they will need to help of the Marines. Starting in a few months, a group of 600 Marines at Camp Pendleton in California will face rifle training with not only foam plugs in their ears, but also a drink that tastes very much like wild berry herbal tea.
They are advised to take this drink with every meal as they participate in the notoriously loud training period that goes for two weeks, an event that is known to lessen the ability of the participant to hear by 10 percent. When everything turns out as expected, the substance infused into the drink makes a difference and the hearing tests must be able to strengthen this claim. The latest wrinkle in finding the pill that shall protect and perhaps cure the troubles brought by loud noise is this. Even as the effort is not really new, industry leaders maintain that it has picked up steam in the last years.
Based on the report from the federal government, hearing loss due to exposure to noise is found to be the first when it comes to the most common occupational health troubles and second among the most self reported occupational maladies or injuries. The figures of Americans now suffering from long term hearing loss has grown already to 10 million and these are the people who either get exposed to a loud explosion or to noisy surroundings on a long term basis. And now, it has been estimated that 30 million people go to work with a degree of noise hazards such as mining, construction, manufacturing and agricultural workplaces.
People from the world of professional music should also take care. Just some months ago, a man from a big band suddenly had to duck and cover his ears as soon as a trumpet behind him wailed and made him realized the value of wearing his ear protection first before anything else. Beware of recreational shooting, snowmobiling and motorcycling as these can be hazardous as well.
You may put on your specialized sound deadening earmuffs or trusty earplugs, but remember that these may not be enough. They get overwhelmed by a few varieties of sounds. Most would not bother to wear these even if they should, and others on the other hand are just susceptible to damage in their hearing capability. Plus, some levels of sound can destroy hearing by reaching the skull even if there is some sort of protection in the ears.
This is due to the fact that loud noise that comes in brute force may not always be the reason for damage caused to the inner ear which is extremely delicate. For there are times when it only provokes the inner ear enough to make it produce harmful oxygen molecules ? free radicals. Antioxidants neutralize free radicals, and the ear naturally has such defenses. But with enough noise settling in, the ear's antioxidants get overwhelmed so much.
In this scene, free radicals create damage that leads to the demise of the receptors of sound found inside the ear. As you look at the equation of strengthening the antioxidant defenses of the ear to become both a prevention as well as quick correction means for any damage on the ear after long exposure to noise, you will see that it makes so much sense. Animal experiments in prevention look promising, and people are getting very excited about applying this to protection against noise exposure in humans.
There is one pioneer in the field of antioxidants for hearing who states that he has seen its marvelous effects on different patients. He obtained a patent on the nutritional supplement that he recommends to many of his patients that require help from hearing loss problems out of causes such as aging and high levels of noise in their surroundings. Many of these patients saw the wondrous improvement when it came to their hearing and also felt the progression of their hearing loss getting slower. Even as this did not prove to be enough to make people who suffer from a moderate to sever degree of hearing loss and did not make them throw their hearing aids away, it was still very much able to make them switch to a less potent mode or perhaps set theirs aside for some time.
The Marine experiment leading scientists and his colleagues obtained impressive feedback in their laboratory animal experiments utilizing a range of different antioxidant compounds. NAC or N acetylcysteine is where he has set his eye on, and it is the same substance that is approved by the federal authorities to reverse the damaging effects of a famous painkiller. With the NAC working to neutralize the ear's free radicals, the ear's antioxidant defenses are made better. Before and after the animals got exposed, NAC was given and this has significantly reduced hearing loss. The effect generally means the difference on whether or not you need a hearing aid, when translated for humans.
