For people with HFHL, it can be as though someone has removed certain letters from the alphabet in speech.
Clearly the best thing to do is to be knowledgeable about the types of causes for hearing loss and how to avoid them. Should the worst occur and you have discovered some hearing loss, there are some options available. While there are treatments available, and there are new breakthroughs happening all the time in the field, the best measures to take are ones of prevention. Caring for the ears is as simple as identifying the hazards and putting measures in place to either avoid or protect from these hazards. When aiming to treat, instead of only protect, The Hearing Loss Pill team has created a post specifically covering all of the available options which include everything from stem cell treatments to cochlear implants.
Some data from studies is showing that high frequency hearing loss is actually getting worse in the main population, particularly in the youth. A: Possible causes for HFHL include extreme noise exposure, genetics, aging, ototoxicity, and desease.
A: Hearing Aids can take the higher frequency sounds, not heard by someone with HFHL, and lower the frequency one of two ways. Sensory presbycusis: This refers to epithelial atrophy with loss of sensory hair cells and supporting cells in the organ of Corti. Mechanical (ie, cochlear conductive) presbycusis: This condition results from thickening and secondary stiffening of the basilar membrane of the cochlea. The rest of my answer is based on this book, some parts of which exist online (which I'll quote). As you can see from the graph, severity of age-related hearing loss depends on sound frequency: older people need high-pitched sounds to be displayed more loudly, in order to hear them. It's not described much on the website, but the book explains that there is a relationship between how loud a sound has to be to harm you, and which frequency it is.
Here's a plot of the connection between loudness and frequency in auditory perception, in which you can see that sounds around 4kHz can most easily harm us. Does this explain that when I was younger, I was more sensitive to sound and slept less well? Not the answer you're looking for?Browse other questions tagged medical-science or ask your own question.

But they may have hearing loss because they’re all eating the same junk and not getting enough nutrients. Fortunately, by adding a few important foods to what you eat, you can stop the decline in your ability to hear.
Cold-water, high-fat fish like mackerel, wild salmon, lake trout and herring are good sources.
If you’re currently in good health, I recommend you get at least 800 mcg per day of folate and 100 mcg of B12 every day.


Also, avoid non-steroidal anti-inflammatory pain relievers because they have been shown to increase the risk of hearing loss. A study from Taiwan showed that selenium protects your ears from toxicity in the environment.
Tinnitus is a condition in which damage to the ear results in sufferers hearing sound or noise that isn?t there. Hearing deteriorates with age to a certain degree, and this decline can be exacerbated by any number of other factors. The goal is to become educated on the risks of damaging noises and to minimize any potential hearing loss as we age. These can range from heavy-duty work earmuffs that cover the whole ear to small, inconspicuous plugs for watching bands. HFHL usually impairs the inner ear, which affects how sound is received and transmitted as signals to the brain.
Obviously this plan will differ person to person: a truck driver might identify far different noise hazards than a full-time mother.
Frequency transposition, the first option, takes the higher frequency energies and moves them to a lower frequency. The truth is that most people never do anything with the products they buy, so most of the time, they dona€™t get ANY results. Characteristically, presbycusis involves bilateral high-frequency hearing loss associated with difficulty in speech discrimination and central auditory processing of information. This process originates in the basal turn of the cochlea and slowly progresses toward the apex. The thickening is more severe in the basal turn of the cochlea where the basilar membrane is narrow. The question is being unable to hear ranges as we get older, starting from childhood, while presbycusis is specific to post middle-aged people. Sounds that are near our auditory thresholds (under 20 Hz and above 20.000 Hz in the normal, healthy hearing range) can't harm us even if they are extremely loud. You get almost 7 grams of omega-3 in each tablespoon of Sacha inchi, and nearly a gram with each teaspoon of cod liver oil. Selenium is a mineral and antioxidant, which has a protective effect against hearing loss.
What happens is the tiny hair nerves that are contained in the basilar membrane die as a result to over-exposure to loud noises.
It might not even be something noticeable at the time; rather, it will be a slow deterioration.
Carrying around a pair of the smaller ones are a good idea, especially if you think you might be exposed to noise. While there is no cure as such for hearing loss, there are a range of treatments and aids to improve the quality of hearing.
There is only a limited amount of times the ears can be exposed to loud noises before they start to deteriorate. A range of ear protection, from the large rubber earmuffs to smaller earplugs, are a great investment and should always be close to hand ? This is hypothesized to be due to noise induced hearing factors from an increase of noise in daily activities, including everything from normal environmental noise to the increased use of ear buds for music listening.


The second way, known as nonlinear frequency compression, uses a compression ratio on the high frequency sound to lower it.
These changes correlate with a precipitous drop in the high-frequency thresholds, which begins after middle age. This correlates with a gradually sloping high-frequency sensorineural hearing loss that is slowly progressive. The wiki page does refer to the issue as presbycusis, yet every reliable source on presbycusis lists it as being limited to post middle-aged people. We don't hear them because they cause no mechanical change in our ear that responds to those frequencies, and consequently no harm is done. Not only is tinnitus aggravating and nerve-racking, but it decreases your ability to hear other things because of the background noise. These hair nerves are what transmit sound to the brain to be interpreted into aural messages ? This means that instead of taking in a whole day?s worth of exposure to loud noises, we see them as isolated incidents.
We know better than that: we cover up our skin, we use sunblock, and we get our skin checked for moles and melanomas. A medical practitioner will be able to determine exactly what hearing loss you suffer from, as well as in what frequencies, and will be able to recommended treatment. The testimonials you see on this web site are some of our better results and are not typical. The abrupt downward slope of the audiogram begins above the speech frequencies; therefore, speech discrimination is often preserved.
It seems the wiki page is the only source referring to range of audible frequencies in young people as presbycusis?
In the case of age-related hearing loss, the hair cells in the inner ear that should respond to high-frequency sounds, have already stopped responding, so there is nothing left to harm. Only a very low percentage of patients will ask for a hearing test when they visit their GP.
Any music lover should consider the volume levels they enjoy their music at, as many people turn music up far too high (especially with ear-buds). Hearing aids, sound therapy and possibly surgery are all methods that are used to help amplify and possibly correct to a degree a person?s hearing.
They stuck to the dose as directed and maintained a healthy lifestyle and balanced diet alongside it. Histologically, the atrophy may be limited to only the first few millimeters of the basal end of the cochlea. If there is a ringing noise in the ears in an otherwise silent room, this is tinnitus1 and suggests that the ears have been over-exposed to noise. If it?s someone who works with heavy machinery, or in areas of high traffic, or even as a bartender, a day?s worth of sound exposure could be happening at levels that damage the ears.
One theory proposes that these changes are due to the accumulation of lipofuscin pigment granules.
