Sidebar: Banking Bones To Save Hearing
An important tool for studying disorders of hearing and balance is post-mortem examination under the microscope of human temporal bones. In principle, this is not new for centuries, microscopy of the ear has shown the normal anatomy and the pathologic changes arising from diseases and disorders. Early in the 20th century, scientists began collecting and preserving temporal bone and developing and standardizing methods of measuring and counting inner-ear cells.
Four Levels Of Deafness
There are four levels of deafness or hearing impairment. These are:
- Mild deafness or mild hearing impairment: The person can only detect sounds between 25 and 29 decibels . They may find it hard to understand the words other people are saying, especially if there is a lot of background noise.
- Moderate deafness or moderate hearing impairment: The person can only detect sounds between 40 and 69 dB. Following a conversation using hearing alone is very difficult without using a hearing aid.
- Severe deafness: The person only hears sounds above 70 to 89 dB. A severely deaf person must either lip-read or use sign language in order to communicate, even if they have a hearing aid.
- Profound deafness: Anybody who cannot hear a sound below 90dB has profound deafness. Some people with profound deafness cannot hear anything at all, at any decibel level. Communication is carried out using sign language, lip-reading, or reading and writing.
A New Approach To Researching Cisplatin
The new study differs from previous research because it is a comprehensive look at the pharmacokinetics, or concentration, of the drug in the inner ear, explained study investigator Andrew Breglio, of NIDCD.
The research team primarily used a technique called inductively coupled plasma mass spectrometry to quantify the amount of platinum left in inner ear tissue following cisplatin treatment in mice.
Lisa Cunningham, Ph.D., of NIDCD, who led the research team, noted that instead of using one high dose of cisplatin with mice as other studies have, they developed a treatment protocol like those used in everyday care, in which the drug is given in cycles.
Testing done following each cisplatin cycle showed increasingly progressive hearing loss in the mice. The researchers also measured platinum levels in various organs throughout the drug cycles and found that, whereas other organs eliminated the drug relatively quickly, the cochlea retained the cisplatin, showing no significant loss of platinum 60 days after the last administration of the drug.
In both the mouse model and in studies of human tissue, the researchers determined that the platinum accumulates in a part of the cochlea called the stria vascularis, which, Breglio explained, regulates the makeup of the fluid that bathes the sensory hair cells in the ear and is critical to their proper function.

How It Affects What You Hear
Low-frequency hearing loss is defined as a reduced ability to hear low-pitched sounds, such as men’s voices, bass sounds in music and thunder. How well you hear these soundsor notdepends on the degree of your hearing loss, which can range from mild to profound.
When it comes to speech, this type of hearing loss mostly affects how you perceive the volume of speechas in, how loud it sounds. It also makes it harder to hear vowel sounds, which are spoken at a lower-pitch than consonant sounds. Unlike high-frequency hearing loss, it’s helpful to have people speak louder, as it will improve your ability to hear lower sounds .

The Story Behind Tinnitus
Technically, tinnitus isnt a disease. Its a symptom.
Usually, people with tinnitus also have some degree of hearing loss. Tinnitus often is associated with damage to high frequency hearing, most commonly due to exposure to loud and/or prolonged noise.
Less commonly, tinnitus may be accompanied by an exaggerated sensitivity to sound, known as hyperacusis.
Although tinnitus is most commonly associated with hearing loss, other conditions and lifestyle histories are linked to tinnitus as well. Its important that people who experience tinnitus discuss it with their primary care physicians. They may be referred to see a physician expert in ear disease, typically an otolaryngologistor an ear, nose, and throat specialist for a hearing test and to determine whether or not there is an underlying cause that requires medical attention.
Among other things, tinnitus has been linked to:
- Ear and sinus infections or congestion
- Blockage of the ear with wax or another object
- More than 200 medications, including some as common as NSAIDs . Experts generally believe this is due to the medications effect on the cochleapart of the inner ear that is essential for hearing. Some medications can have a temporary effect on hearing, which stops when the medication is discontinued. Other medications, such as some chemotherapy drugs, which are known to be ototoxic, may cause permanent hearing loss and associated tinnitus.
- Vitamin B12 deficiency
Symptoms Of High Frequency Hearing Loss
High frequency hearing loss is one of the most common types of hearing loss. Although it can affect people of any age, it is more common in older adults and people exposed regularly to loud noises. Specifically sounds in the frequency range of approximately 2,000 Hertz and 8,000 Hz become difficult to hear.
So how can you tell if youre experiencing high frequency hearing loss? There are some obvious symptoms to watch out for, which include:
- Having trouble understanding the voices of adult females and children, but have an easier time understanding adult male voices.
- Having trouble distinguishing consonants in speech, such F, H, or S, which makes speech sound muffled this may be exacerbated when talking on the telephone or watching TV.
- Difficulty hearing birds singing or chirping.
- Difficulty hearing devices that beep, such as the microwave or an alarm clock.
- Having trouble hearing treble sounds in music.
- Having a difficult time hearing conversations in large gatherings or noisy places with background noise.

Finding A Provider For Your Child
Seek help right away if you suspect your child has hearing loss. Oftentimes, your pediatrician is a good place to start. She may refer you to a pediatric audiologist or an ear, nose and throat doctor. This primer on different types of hearing specialists may come in handy as you navigate your child’s journey to better hearing.
Degrees Of Hearing Loss
Depending on the damage done, individuals experience different degrees of hearing loss. One of the most common causes of hearing loss that corresponds to varying degrees of hearing loss is exposure to loud noises. As noted previously, humans have a range of decibels they can hear, a portion of which is considered the normal hearing range.
This standard range is between 0dB and 180dB. However, by consensus, noises above 85dB can cause damage to ones ears. Sounds at 85dB typically require extended periods, roughly 8 hours, to cause permanent damage, though. At 100dB, damage can occur within 15 minutes. Sounds greater than 1250dB can immediately cause damage.
To get an understanding of the decibel level of sounds, see below.
- Restful breathing 10dB
- Standard human speech 55- 60 dB
- Washing machine70dB
- A busy public area/car traffic 80dB
- A concert100-110dB
- A siren/alarm 110dB
- A plane taking off- 130dB
For further context, concerts can cause some degree of hearing loss within 15 minutes. If an individual were to stand near a plane while it took off, the engines would do instant damage to their hearing without ear protection. This damage would be irreparable.

Common Causes Of High Frequency Hearing Loss
High frequency hearing loss can impact people of all ages and backgrounds. Some of the most common causes of this type of hearing issue are:
- Noise. The National Institute on Deafness and Other Communication Disorders reports that over 10 million people in the U.S. alone suffer irreversible damage from noise-induced hearing loss. Each day, up to 50 million Americans are exposed to dangerous levels of noise. This can happen from a single exposure, such as an explosion, or long-term exposure to noise over 85 decibels .
- Genetics. Family history can play a role in hearing loss. Its possible that you are genetically predisposed to this condition if you have family members that have suffered from high frequency hearing loss.
- Aging. When the aging process leads to hearing loss, its referred to as presbycusis. This is a slower process that generally impacts both ears and is more difficult to notice. The first sign is the inability to comprehend speech in certain environments and hear high-frequency sounds.
- Disease. Certain diseases can lead to high frequency hearing loss. In children, this includes chronic untreated ear infections, also known as chronic otitis media. In adults ages 30 to 50, Menieres disease can lead to tinnitus, vertigo, and partial hearing loss.
- Medication. Some types of drugs can lead to high frequency hearing loss. These include aminoglycoside antibiotics, some chemotherapy drugs, and aspirin taken in large quantities.

Say What Understanding High Frequency Hearing Loss
Do you struggle to hear, but only when it comes to specific voices or sounds? For example, you might have no trouble hearing the local newscasters voice on television at night, but youre unable to hear the birds chirping outside or a small child speaking.
If the above scenario sounds familiar, you may be suffering from high frequency hearing loss.
While hearing loss is prevalent in older Americans, this isnt an issue that is isolated to the over 65 crowd. According to a recent study published by JAMA, the number of U.S. adults ages 20 and older with hearing loss is expected to increase from 44 million in 2020 to 74 million by 2060. This can be caused by such things as loud music, certain medications and illnesses, damage to the eardrum, and, of course, aging.
Being unable to hear at higher ranges is one of the first signs of hearing loss. While this can create a variety of challenges in your life, it is also something you can address with the right hearing devices.

What Is Sensorineural Hearing Loss
There are three parts to your ear: the outer ear, the middle ear, and the inner ear. Sensorineural hearing loss affects the inner ear.
The inner ear contains the cochlea, where vibrations coming through the ear canal are changed to electrical neural signals, which are then transferred to the brain through the auditory nerve.
Sensorineural hearing loss occurs when one, or both, of these functions of the inner ear are damaged. Damage to the cochlea or auditory nerve means that sound vibrations are not converted into impulses and carried to the brain in a way it understands.
This type of hearing loss is characterised by having trouble hearing quiet or high-pitched sounds. If youre affected by sensorineural hearing loss, you may feel as though people are mumbling or sounds may seem softer.
What causes it?
Sensorineural hearing loss is very common and can be caused by a variety of factors. Many people will experience some form of this hearing loss as they age, due to natural wear and tear of the body. However, there are some more concrete causes, which you can try to protect yourself from.
AgeingPresbycusis, or hearing loss due to ageing, is a common type of sensorineural hearing loss. If you are over 60 years old and have hearing problems, there is a chance you could have presbycusis.
Loud noisesThe most common cause of sensorineural hearing loss, loud noises directly damage your cochlear structures. You can avoid being affected by loud noises by protecting your ears.

Treatments For Childhood Hearing Loss
Depending on the severity and cause of hearing loss in your child, hearing aids, cochlear implants and a combination of speech therapy or assistive listening devices might be recommended forms of treatment. If you notice that your infant or child shows any of the above signs, take him or her to your family doctor, who can refer you to a pediatric audiologist to have your child’s hearing tested. If a child has wax buildup, an ear infection or another problem causing temporary hearing loss, the audiologist will take care of the problem or refer you to an otolaryngologist to have the temporary hearing obstruction treated.
There has never been more hope for children with hearing loss, even those with severe hearing loss.
Audiologists can perform in-depth behavioral hearing examinations for even very young children . There are several objective tests that infants, toddlers and young children can undergo as well. These tests are painless and non-invasive. After the exam, the audiologist will spend time talking with you about your child’s hearing ability and recommend an appropriate treatment plan or medical intervention.
