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.
This occurs when sound is not conducted efficiently through the outer and middle ears, including the ear canal, eardrum, and the tiny bones, or ossicles, of the middle ear.  Conductive hearing loss usually involves a reduction in sound level, or the ability to hear faint sounds.
This type of loss not only reduces the intensity of sound, but often the clarity of speech as well. Current statistics indicate that hearing loss is now the third most prevalent chronic health concern among adults in the US.
Protecting one’s hearing when exposed to loud sounds, or avoiding loud sounds if possible, is key when it comes to hearing protection. Common areas that may have potentially damaging levels of noise exposure (above 85 decibels) may be the use of power equipment, like lawnmowers. As sounds travel through our ears, they eventually wind up in our senroy organ of hearing: the cochlea.
Stock up on all hearing aid batteries for all major hearing aid manufacturers as well as ear plugs and accessories. 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.
Depending on the degree and pattern of the loss, many report that they can hear but cannot understand conversation.   Most individuals with sensorineural loss can be helped by hearing aids and other assistive devices.
Regardless of the source of noise, if it is too loud to hear someone’s voice above the din, than it is probably too loud and hearing protection should be used. 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.
The average 8th grade student today is 4 times as likely to suffer from noise induced hearing loss than 10 years ago. The one thing we can control is noise exposure; weather it be work related or recreational.
The hair cells have an important job of passing on the information from the sound waves to the part of our brain that interprets sound. Roughly speaking, the frequency patterns of hearing loss are divided up into: Low-frequency, mid-frequency, high-frequency, notches, and flat. If these cells are damaged, or missing, they cannot pass along the sounds and the listener misses out on all or part of the signal.
