If you have a high frequency hearing loss, it means that you do not hear tones or parts of speech which are high frequency.
The exact numbers vary, but most authorities agree that the frequency range of human speech goes from about 250 Hz all the way up to 9,000 Hz, with the majority of speech taking place in the 500 Hz to 3500 Hz range. There are many causes of high frequency hearing loss, and sometimes your hearing loss may be due to several of these causes. If you’d like a free phone consultation with a licensed hearing provider, please feel free to call us at 800-731-6794. 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.

Hearing aids are characterized by steady progress in technological advancement, even while the lack of progress in lowering hearing aid prices and improving distribution continues to frustrate hearing aids users. Within the behind-the-ear (BTE) hearing aid category, hearing aids can be further subdivided into Receiver-in-the-Aid (“RITA” or “traditional”) and Receiver-in-the-Canal (“RIC”). If it seems obvious that placing the speaker in the canal will yield better, relative to forcing sound to travel an extra distance through an external tube… well, that’s about right. A 2010 paper for the Journal of American Audiology that compared RITA to RIC hearing aids found that RIC models were equal or superior in all measured respects. In short, the study strongly suggested the superiority of RIC hearing aids for mild to moderate hearing aids (and is one of the reasons Embrace Hearing sells RIC devices). Because hearing aids are only replaced once 3-5 years, it takes time to observe whether the implications of academic studies are actually being observed in clinics across the country and translating into differences in recommendations and ultimately hearing aid fittings.
Today, almost 75% of hearing aids sold in the US are "BTE"s and of those, the vast majority are "RIC"s (receiver in canal). Finally, we believe that since 27 million Americans are living with untreated hearing loss, the legacy distribution system of brick & mortar audiologist practices is failing many of the people it is theoretically supposed to help -- largely because the inefficiencies of running individual practices with high fixed costs forces audiologists to charge through the nose, pricing millions of consumers out of the market. We've written before about high hearing aid prices, and the cost benefits to buying online. In fact, our research revealed that hearing aids are much, much more expensive, on a per-gram basis.
In all fairness, this approach penalizes manufacturers for making technological strides to reduce the weight of hearing aids, and increase comfort and satisfaction.
In fact, our internet research turned up a long list of luxury items with a lower price-to-weight ration than hearing aids.
It actually took us a while to identify any substance, manmade or otherwise, with a higher price-to-weight ratio than modern hearing aids.
Recently, the Better Hearing Institute announced a campaign encouraging employers to emphasize hearing health in their workplace wellness programs. The Institute noted research linking hearing loss to such chronic conditions as Alzheimer's, kidney disease, diabetes, and even heart disease.
Further, untreated hearing loss is linked to reduced earnings, increased workplace absenteeism, and lower workplace productivity, as well as depression, anxiety, and cognitive decline.
In fact, a study published in the International Journal of Audiology found that employees with hearing loss are as much as five times more likely than their co-workers with normal hearing to experience stress so severe that they must take more sick-days. 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?

Remember, high frequency hearing loss is not a type of hearing loss, it can be thought of as the nature of the hearing loss.
If you break down human speech, vowels are in the low frequency range- between 250 Hz and 1000 Hz. The majority of time however, high frequency hearing loss is caused simply be the general aging process. Tiny hair cells that line the cochlea (a sensory organ inside the inner ear) pick up sound waves and transform them into nerve signals that the brain interprets as sound. Hearing aids magnify sound vibrations so your surviving hair cells can detect those more powerful vibrations and convert them to signals that are then sent to the brain. 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. We’ve frequently written about issues with hearing aid costs and hearing aid distribution; this entry will focus on technological progress, as represented by the increasing popularity of receiver-in-canal technology.
The receiver – or speaker – amplifies sound, which must pass through a tube to the ear canal (in an RITA) or is simply projected directly from a speaker in the canal (in an “RIC”). In just a few years, a combination of technical advancements, empirical academic studies, and coordination between manufacturers and audiologists and hearing aid dispensers let to a major improvement in the types of hearing aids distributed. We'll go into more detail on the price of hearing aid follow-on services in a future entry.
DiSarno has assembled a number of convincing reasons to avoid many online hearing aid vendors. But we do believe strongly in consumer choice, and we  believe that customers can evaluate for themselves the wisdom of paying $5,000+ for hearing aids in person or $1,000 - $2,000 online, for near-identical devices.
This represented the healthcare industry turning on itself, as current inefficiencies had simply become too great an opportunity too great to ignore for insurers -- which traditionally have little involvement in hearing aids. On this list are caviar, saffron, uranium nuclear fuel, a top-of-the-line artificial heart, and the Space Shuttle Endeavor. In fact, three out of four hearing aid users report improvements in their quality of life due to wearing hearing aids. Additionally, hearing loss is linked to a greatly increased risk of injury-causing falls among people aged 40-69.
While the online test is not a substitute for a comprehensive audiologist-administered exam, it can serve as a "wake-up call" that encourages people to seek professional care. One reason may be that only four in ten people with moderate-to-severe hearing loss use hearing aids. Use of hearing aids was shown to reduce the risk of income loss by 90 to 100 percent for those with milder hearing loss, and from 65 to 77 percent for those with severe to moderate hearing loss.
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.
What is the difference between \section{Section Name} and \section[ something here]{Section Name}? Sure, most high frequency hearing losses are sensorineural hearing losses, but you could absolutely have a conductive hearing loss that is high frequency in nature as well.
When these hair cells become damaged or die over time, those sound waves are not effectively transformed in to nerve signals, so the sound never reaches the brain. So essentially, hearing aids are “waking up” hair cells which were not working well enough, and then the hair cells do the rest of the work and send the signals to the brain. 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.
The real winners here are hearing aid users, who are likely to experience improved satisfaction with their hearing aids and ultimately improved quality of life. We read recently that hearing aids cost more than their weight in gold, and decided to do some myth-busting. And studies show that when people with even mild hearing loss use hearing aids, they improve their job performance, increase their earning potential, enhance their communication skills, improve their professional and interpersonal relationships, and stave off depression. 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. But the fact is, there are many parts of speech which are above 2,000 Hz as well, and that’s where the problem lies. On the other hand, consonants are in the high frequency range- between 2000 Hz and 3500 Hz. This means that when you wear hearing aids, they are only making some sounds louder- not all of them. 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. Hearing aids (when properly programmed) are only going to make those sounds louder which you aren’t already hearing.
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. So if you are suffering from a high frequency hearing loss, it is because you are hearing the vowels properly, but not the consonants. The result is getting those high frequency sounds back, and hearing speech much more clearly.
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. With a high frequency hearing loss, it becomes very difficult to get any clarity out of speech- everything sounds very mumbled.
If you believe you have a high frequency hearing loss, your best course of action is to see a hearing aid provider near you, get a free test done, and start a free trial period with hearing aids.
One theory proposes that these changes are due to the accumulation of lipofuscin pigment granules.
Today’s hearing aids are incredibly intelligent, can be 100% invisible, and are very comfortable- give them a try!
