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.

For over 17 years, the NYOG has specialized in the ear, nose and throat, and ranks among the country's leading diagnostic and treatment centers for otolaryngology-related illnesses.
Taking care of your hearing is important, especially since we now live in such a noisy world. There are many things you can do, like wearing earplugs when you know you are going to be in a situation where noise levels are extreme, or avoiding these situations altogether, as well as being responsible with the volume levels of your music devices and television.
Continued exposure to these and other excessive environmental noise is a major contributor to hearing loss.
If you are experiencing hearing loss in one or both ears, or if you have a constant ringing [also known as tinnitus (tin-NY-tus)] or any pain or ache, come in to see us. Meniere’s Disease, also known as Endolymphatic Hydrops, is an inner ear disorder that is caused by an overproduction or underproduction of endolymphatic fluid found within the cochlea or inner ear.


As a result of the pressure changes of the inner ear, fluctuating low frequency hearing loss occurs, which can become permanent and worsen over time.
The exact cause of Meniere’s Disease is unknown, however there several factors that may contribute to it. Gentamycin: A steroid injection applied across the eardrum to the inner ear to help resolve some of the symptoms. Hearing Aids will help to improve audibility and localization of sounds in one’s every day listening situations.
Labyrinthectomy, removal of the inner ear, and a Chemical Labyrinthectomy, a drug used to destroy the vestibular (balance) system, may be recommended however only as a last resort. We have 3 locations in Calgary: North, North West and South and an office in each Okotoks, Cranbrook and Creston, and Invermere, British Columbia.
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. NYOG physicians have consistently been recognized among the city's foremost doctors within their areas of specialization. Whether you live in a big city, like New York City, the suburbs or a rural area, technology can provide many opportunities for damaging your hearing. Whether environmental, health-related or genetic, our docs will get to the root of the problem and provide solutions. Because the hearing loss occurs more in the low frequencies, it becomes difficult for people to hear low pitched sounds. However, further testing by an Ear-Nose and Throat (ENT) Specialist is necessary to confirm this diagnosis.


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. Staffed by an exceptional team of board-certified physicians and specialists, the NYOG adheres to a comprehensive disease management approach to ensure its patients receive the best possible care of their sinus, head and neck, hearing and balance, speech and swallowing, and sleep apnea conditions. We are here to answer any and all of your questions because at NYOG…we are here to clear things up.
The increased pressure can break through the membranes to the inner ear and cause an abnormality in the chemical make-up of the fluid. 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. As well, its facial plastics practice offers a broad array of facial reconstructive surgeries and cosmetic procedures. Other symptoms of Meniere’s Disease include roaring tinnitus, sudden and spontaneous vertigo (dizziness), and pressure changes in the ears. Histologically, the atrophy may be limited to only the first few millimeters of the basal end of the cochlea. One theory proposes that these changes are due to the accumulation of lipofuscin pigment granules.
