Presbycusis is defined as hearing loss associated with the degenerative processes of aging. Sensory presbycusis is caused by atrophy of the organ of Corti and involves the distal-most segments of the auditory neurons located at the basal turn of the cochlea. Schuknecht described neural presbycusis as a diminished population of auditory neurons all throughout the cochlea and auditory pathways. Not only do the sensory and neural mechanisms of the peripheral auditory system age, but the central auditory pathways degenerate, as well.
Finally, a review of the aging ear would be incomplete without a discussion of the concomitant changes to the external and middle ears. As the sizeable generation of baby-boomers ages, these classic studies on presbycusis become more and more relevant to hearing care providers in that they provide scientific evidence of the auditory changes than can be expected to occur with the aging process. Abstract Noise-induced permanent threshold shifts (NIPTS) were computed from retrospective audiometric analyses by subtracting aging effects on hearing sensitivity in sixty-eight patients with bilateral sensorineural hearing loss who reported significant occupational noise exposure histories.

As an overview, low frequency (or tone) sensorineural hearing loss (LF SNHL or LT SNHL) is unusual, and mainly reported in Meniere's disease as well as related conditions such as low CSF pressure. Le Prell et al (2011) suggested that low frequency hearing loss was detected in 2.7% of normal college student's ears. Oishi et al (2010) suggested that about half of patients with LTSNHL developed high or flat hearing loss within 10 years of onset. The new international criteria for Meniere's disease require observation of a low-tone SNHL. Gatland et al (1991) reported fluctuation in hearing at low frequencies with dialysis was common, and suggested there might be treatment induced changes in fluid or electrolyte composition of endolymph (e.g. Although OAE's are generally obliterated in patients with hearing loss > 30 dB, for any mechanism other than neural, this is not always the case in the low-tone SNHL associated with Meniere's disease. The lack of universal correspondence between audios and OAE's in low-tone SNHL in at least some patients with Meniere's, suggests that the mechanism of hearing loss may not always be due to cochlear damage. Of course, in a different clinical context, one might wonder if the patient with the discrepency between OAE and audiogram might be pretending to have hearing loss. Papers are easy to publish about genetic hearing loss conditions, so the literature is somewhat oversupplied with these. Bespalova et al (2001) reported that low frequency SNHL may be associated with Wolfram syndrome, an autosomal recessive genetic disorder (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness).
Bramhall et al (2008) a reported that "the majority of hereditary LFSNHL is associated with heterozygous mutations in the WFS1 gene (wolframin protein).
Eckert et al(2013) suggested that cerebral white matter hyperintensities predict low frequency hearing in older adults.
Fukaya et al (1991) suggested that LFSN can be due to microinfarcts in the brainstem during surgery. Ito et al (1998) suggested that bilateral low-frequency SNHL suggested vertebrobasilar insufficiency. Yurtsever et al (2015) reported low and mid-frequency hearing loss in a single patient with Susac syndrome. There are an immense number of reports of LTSNHL after spinal anesthesia and related conditions with low CSF pressure.
Fog et al (1990) reported low frequency hearing loss in patients undergoing spinal anesthesia where a larger needle was used. Waisted et al (1991) suggested that LFSNHL after spinal anesthesia was due to low perilymph pressure. Wang et al reported hearing reduction after prostate surgery with spinal anesthesia (1987). We have encountered a patient, about 50 years old, with a low-tone sensorineural hearing loss that occured in the context of a herpes zoster infection (Ramsay-Hunt). LTSNHL is generally viewed as either a variant of Meniere's disease or a variant of sudden hearing loss, and the same medications are used. Sensorineural hearing loss is another type of hearing loss also known as SNHL or Sensor neural hearing loss. Mixed hearing loss is the type of hearing loss that conductive hearing loss and sensorineural hearing loss is in combination.
Even though there are other complications of chronic suppurative otitis media, the aspect of hearing loss is often studied. References1.Bluestone CD (1981) Recent advances in the pathogenesis, diagnosis, and management of otitis media.

Schuknecht’s article appeared almost 40 years ago, his findings have been supported by and cited in many other studies since its 1964 publication.
The structural changes in the organ of Corti that lead to sensory presbycusis may begin in early childhood and typically progress very slowly.
Obviously, the transmission of an auditory signal through the central auditory pathways and the decoding of this signal at the level of the auditory cortex depend on a minimum number of neurons that are 1) healthy and fire in a normal pattern at the periphery, and 2) adequately and without distortion transmit auditory information through the higher central auditory pathways to the temporal cortex for processing. Occurrence in isolation leads to the typical audiometric pattern, whereas a combination of effects can lead to additive audiometric results that appear to have mixed pathological causes.
The external ear canal is subject to structural changes that result in cracking and bleeding of the skin that lines it,5 as well as thick, dry wax and itchy, accumulating debris.

There were significant effects of age on NIPTS but no significant gender- or ear- differences in terms of NIPTS. Sensorineural Hearing Loss Associated with Occupational Noise Exposure: Effects of Age-Corrections.
To us, this seems a little overly stringent, compared to the earlier 1995 AAO criteria that just required any kind of hearing loss, but criteria are better than no criteria. That being said, genetic conditions should not be your first thought when you encounter a patient with LTSNHL. One would think that diabetes insipidus is so rare that hearing loss is probably not the main reason these individuals are seeking attention. These patients are extremely rare because there isn't much microsurgery done close to the brainstem. We are dubious about the conclusion of this paper because it is different than nearly every other paper in the literature. We are dubious that this has any applicability to humans and we have never seen a patient with lithium toxicity with any LFSNHL. We have observed this occasionally ourselves, but of course, the usual pattern is a conductive hyperacusis.
We find this somewhat plausible as pregnancy and delivery might be associated with spinal anesthesia, with changes in collagen, and with gigantic changes in hormonal status. Nevertheless, the occurrence of sensorineural hearing loss in patients with this disease is still controversial.
I found the article to be an oldie but a goodie, with excellent potential as a teaching piece. Some discoveries and findings in science and medicine have little practical applicability, but his research is directly relevant to interpreting the audiometric results we find on many of our more senior patients who have hearing loss. As a result, the audiometric pattern remains as a precipitous high frequency sensorineural hearing loss with good threshold preservation of the speech frequencies. Neural presbycusis is not manifested until the number of normally functioning neurons falls below a critical minimum. Schuknecht’s book was published, he nonetheless developed the theory based on the audiometric data archived in his laboratory on patients whose temporal bones later became available post-mortem and on the histopathological research data available at the time. Vascular and neurological degenerative processes, other chronic medical conditions associated with aging, and some medications used by elderly patients can also lead to cognitive changes that mimic hearing loss or appear to exaggerate existing hearing impairment. Neural presbycusis is characterized as a degeneration of neurons and results in hearing loss similar to sensory presbycusis. Mechanical or cochlear conductive presbycusis shows the typical bilateral sloping high frequency sensorineural pattern of hearing loss, but with good preservation of cochlear elements (sensory and neural cells) speech understanding is generally good. Although these changes have no effect on audiometric function and are not considered presbycusis per se, they can cause obvious discomfort to older persons wearing amplification. In this 40-year-old article by one of the most prolific and respected otologic researchers, surgeons and clinicians of all time, Dr. The NIPTS at 2,000 Hz was found to be significantly greater than NIPTS at frequencies 500 Hz, 1,000 Hz, 4,000 Hz, and 8,000 Hz. There is a large literature about genetic causes, mainly in Wolfram's syndrome ( diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), probably because it is relatively easier to publish articles about genetic problems. He defined LTSNH as that the sum of the three low frequencies (125, 250, 500) was more than 100 dB, and the sum of the 3 high frequencies (2, 4, 8) was less than 60 dB.
In other words, Wolfram's is probably not diagnosed mainly by ENT's or audiologists, but rather by renal medicine doctors, as DI is exceedingly rare, while LTSNHL is not so rare in hearing tests. That being said, it is very rare to encounter any substantial change in hearing after pregnancy. It’s mostly permanent because sensorineural hearing loss’ is very hard to be cured by medicals or surgery.
This study aim (1) to assess the association between sensorineural hearing loss and chronic suppurative otitis media, (2) to investigate some clinical factors that might affect the sensorineural component in patients with this disease. Rather, it is a term that represents four distinct degenerative conditions and their corresponding distinct audiometric patterns in their purest manifestation.

So, although the process of neural degeneration may begin early and continue throughout an individual’s life, it might have no appreciable effect on auditory function until the number of healthy neurons falls below that minimum.
In this article he described the three physiological functions of the stria vascularis as: 1) the source for the endocochlear potential, 2) the producer of endolymph and 3) the producer of the energy that the cochlea runs on.
They studied 72 individuals between the ages of 60 and 80 years of age with normal hearing and speech discrimination scores of >80% under monaural syllabic challenge. However, speech understanding is far worse than would be anticipated from the audiogram, in this example, perhaps only 40% to 60% in each ear.
Absent any other contributing medical complications, we can tell them with a reasonable degree of certainty that the degenerative changes in the hearing system associated with aging can involve not only the inner ear which results in hearing loss (that is, a problem with sound reception), but also can affect the central auditory pathways and their parent’s ability to process the very dynamic speech signal (a perceptual dysfunction). Roughly speaking, the frequency patterns of hearing loss are divided up into: Low-frequency, mid-frequency, high-frequency, notches, and flat. This was a retrospective analysis of the clinical records and pure tone audiograms of patients with chronic suppurative otitis media in a Nigerian Tertiary Health Institution from January 2003 to December 2008. Neural degeneration is variable in its age of onset and its severity, both of which are under genetic control. Since the stria vascularis maintains the cochlea’s bioelectric and biochemical properties, any malfunction that affects those properties will naturally result in auditory dysfunction. However, other studies completed from animal preparations have revealed calcification and deposits of calcium salts at the basal turn that resulted in stiffening and a pathological change in motion of the basilar membrane, thereby elevating threshold. All patients were given a comprehensive battery of tests of central auditory function including those that present stimuli under diotic as well as dichotic stimulation and required the subjects to either fuse or separate the stimuli into combined or distinct percepts.
Noises in the distance are simply recognized, but speech must go through a complex decoding process.
Results support models that suggest interactive effects of aging and noise on sensorineural hearing loss in ears with occupational noise exposure.
Also it’s known that some drugs are making toxic effect and creating sensorineural hearing loss.
There are lots of researches why depression is causing hearing impairment and it’s known that depression in every age may cause hearing loss.
Patients with metabolic presbycusis typically have a flat sensorineural hearing loss with excellent word recognition ability at levels where speech is audible. Strategies can then be offered to the patient for more effective listening and to the family for more effective ways to communicate. Living troubles on understanding what people say in standard sound is the most known symptom.
In other words, monaural word recognition scores are far worse than would be predicted from that ear’s puretone findings. This type of presbycusic hearing loss is typically first noted later in life, slowly progresses and exhibits a flat puretone pattern.
They concluded that despite what monaural word recognition scores might show, a perceptual dysfunction will only be evident under binaural and dichotic challenge. The evidence demonstrates that this perceptual dysfunction can occur in the absence of cognitive changes and is more prevalent in older adults. Schuknecht’s descriptions of the four types of presbycusis remain essentially unchallenged after almost half a century.
Also listening TV on higher than normal volume continuously and depression based hearing loss are the main symptoms of hearing impartibility. They stated further, “From a therapeutic standpoint the classical audiogram of the elderly depicting a falling curve in the higher frequency range can be compensated by a selective amplification unit (hearing aid) which, within the limitation of output and feedback, can improve the situation. Therefore, we must stress that these receptive (hearing loss) and perceptual (central presbycusis) manifestations of aging are normal processes and not necessarily symptoms of dementia.
Not so for the defect within the CNS, since amplification alone does not resolve the deficit.
However, should a family express concern about a loved one’s auditory functioning as a symptom of severe cognitive decline, they should be encouraged to seek the expertise of a physician who specializes in geriatrics. Some deep head traumas may cause sensorineural hearing loss and also rarely but aging may cause it. The factors of diminished central suppression or overwhelming central competition increasingly impairs function, as our data indicate” (p.
Patients with chronic suppurative otitis media had a significant degree of sensorineural hearing loss in this study.
The higher frequencies were more affected; however, the patient’s age and duration of otorrhea seem not to have any correlation with the degree of sensorineural hearing loss.
