Hearing Impairment In Infants
The following signs may indicate a hearing problem:
- Before the age of 4 months, the baby does not turn their head toward a noise.
- The infant does not appear to be startled by a loud noise.
- The infant responds to you when they can see you, but respond far less or do not respond at all when you are out of sight and call out their name.
- The infant only seems to be aware of certain sounds.
There Are 4 Basic Types Of Hearing Loss:
There are several degrees of hearing loss, ranging from mild to severe. It is possible to have a hearing loss in only one ear or in both ears .
Do You Also Have Tinnitus
Tinnitus can make it much harder to hear with any given level of hearing loss. If your tinnitus changes from time to time it will mean you can sometimes hear better on some occasions, even though your hearing remains the same, because the sound of the tinnitus will block out what you are trying to listen to.
Tinnitus can also disturb your sleep or make it difficult for you to concentrate. Please visit our pages on tinnitus for more information.

How Old Were You When Your Hearing Began To Change
If your hearing loss began when you were a baby, you will experience your remaining hearing differently than if you began to lose your hearing much later in life. Your voice may be different, and your emotional relationship with your hearing may be different. If you have been accustomed to hearing all your life and then it changes, there are some difficult adjustments to make.

Here are some tips on how you can protect against hearing loss: Employ the 60/60 rule when listening to a portable music player with headphones, listen for no more than 60 minutes at no more than 60 percent of the max volume. Also consider purchasing noise-canceling headphones, as these will require lower volumes.

Stem Cell Transplant And Gene Therapy
A 2005 study achieved successful regrowth of cochlea cells in guinea pigs. However, the regrowth of cochlear hair cells does not imply the restoration of hearing sensitivity, as the sensory cells may or may not make connections with neurons that carry the signals from hair cells to the brain. A 2008 study has shown that gene therapy targeting Atoh1 can cause hair cell growth and attract neuronal processes in embryonic mice. Some hope that a similar treatment will one day ameliorate hearing loss in humans.
Recent research, reported in 2012 achieved growth of cochlear nerve cells resulting in hearing improvements in gerbils, using stem cells. Also reported in 2013 was regrowth of hair cells in deaf adult mice using a drug intervention resulting in hearing improvement. The Hearing Health Foundation in the US has embarked on a project called the Hearing Restoration Project. Also Action on Hearing Loss in the UK is also aiming to restore hearing.
Researchers reported in 2015 that genetically deaf mice which were treated with TMC1 gene therapy recovered some of their hearing. In 2017, additional studies were performed to treat Usher syndrome and here, a recombinant adeno-associated virus seemed to outperform the older vectors.
How To Prevent Noise
The most obvious strategy for reducing noise-induced hearing loss, avoiding harmful noise, is probably the best one. The specific limit usually cited is an average of 75 decibels over 8 hours, or 70 decibels over 24 hours .
In more practical terms, limit your noise exposure like blaring music and noisy places. Occupational safety is also critical. If you work around harmful noises, wear earplugs or other hearing protection devices. Investigate the hearing conservation program available at your job.
Any sort of excessive noise exposure, even background noise, can have an effect. As a result, its wise to get a regular hearing test to check for healthy hearing.

Managing Severe To Profound Hearing Loss
As mentioned earlier, the dynamic range of hearing in severe to profound hearing loss is significantly restricted. Within this narrow dynamic range, differences may exist between individuals in terms of auditory resolution. While some individuals may be able to decode speech successfully using temporal cues, others may need the extra help from visual cues.9
Such differences between individuals aside, careful application of amplification and automatics to achieve maximum comfort, audibility, speech intelligibility, and sound quality is vital. These individuals are long-term hearing aid users and are very conscious of the slightest change in the level or the quality of the sound from their hearing instruments.
What Is The Difference Between Deaf And Deaf
The word deaf is often used to describe or identify anyone that has a severe hearing problem. It is also sometimes used to refer to people that are severely hard of hearing too. The word Deaf, with a capital D, is used to refer to people that have been deaf for all of their lives, or since before they started to learn to talk. They are prelingually deaf.
This is a really important distinction, as Deaf people tend to communicate in sign language as their first language. For the majority of Deaf people, English is a second language, and understanding complicated messages in English can be difficult. There is a strong and close Deaf community within its own culture and sense of identity, based on a shared language.

Social And Cultural Aspects
People with extreme hearing loss may communicate through sign languages. Sign languages convey meaning through manual communication and body language instead of acoustically conveyed sound patterns. This involves the simultaneous combination of hand shapes, orientation and movement of the hands, arms or body, and facial expressions to express a speaker’s thoughts. “Sign languages are based on the idea that vision is the most useful tool a deaf person has to communicate and receive information”.
What Exactly Is Mild Hearing Loss
The definition of mild hearing loss varies depending on the researcher so results indicating the effects of mild hearing loss vary. Some audiologists define mild hearing loss as hearing thresholds of 15-30 dB, others use 20-40 dB. Statistics vary from 1-3% of the newborn population to 54/1000 in the school population. What ever criteria is used results in a significant number of affected children. The topic cannot be ignored.
The Main Types Of Deafness
Sensorineural deafness or nerve deafness a hearing loss in the inner ear. This usually means that the cochlea isnt working effectively. Sensorineural deafness is permanent.
Conductive deafness When sound cant pass efficiently through the outer and middle ear into the inner ear. This is often caused by blockages such as wax in the outer ear, or fluid in the middle ear. Conductive deafness is usually temporary, but it can be permanent in some cases.
Mixed deafness It is possible to have a combination of both sensorineural and conductive deafness, which is known as mixed deafness. One example of mixed deafness is when someone has glue ear as well as sensorineural deafness.
Something else that you might be interested to learn is that deafness in only one ear is called unilateral deafness, and this can also be referred to as one-sided hearing loss or single sided deafness. Interestingly, there are very few deaf children that have no useful hearing. The majority of deaf children can hear some sounds at certain frequencies and loudness.
Degrees Of Hearing Loss
Now that you know the types of hearing loss lets discuss the degrees to which you can experience this disability. Hearing loss itself is the process of a persons decibel threshold being unnaturally raised to the point that normal sounds are not recognizable anymore. What does this mean? Well, to understand this, you have to first know what a decibel threshold is.

What Levels Of Hearing Loss Are There
Hearing loss levels can be mild, moderate, severe or profound. This is decided with the results of your hearing test. A mild hearing loss usually means you have some minor hearing difficulties in some situations, while a profound hearing loss means you cant hear any sounds without an amplification device such as a hearing aid or cochlear implant.
What Are The Levels Of Hearing Loss
There are four general levels, also called degrees, of hearing loss:
- Mild hearing loss describes difficulty hearing soft and subtle sounds like leaves rustling and birds chirping.
- Moderate hearing loss means trouble making out speech sounds at a normal volume level.
- Severe hearing loss indicates you can hear loud sounds or speech, but likely cant hear conversation at a normal volume.
- Profound hearing loss is when only very loud sounds are audible, or none at all.
Someone with mild to severe hearing loss is said to be hard of hearing, while those with profound hearing loss are considered deaf.
Note that the Global Burden of Disease reports that any hearing loss above 35 dB is considered disabling.

How To Pronounce Hearing Loss
Carmen Heron, who is speaking out on behalf of her daughter, who is now legally deaf because of SJS, said.I get emotional even thinking about it. Im just so excited for her. She is still dealing with the aftermath of SJS now, and I do worry and think, Is this the life shes going to have ? But now, its not shell have a new life as a mum. For Heron, who was an apprentice chef at a top Sydney restaurant when she became ill, but can no longer work, life changed forever in early 2014, when she was diagnosed with epilepsy. Right away, she was placed on two drugs commonly prescribed to help manage seizures levetiracetam, more commonly known as Keppra, and lamotrigine, sold under the brand name Lamictal. It took three weeks in the hospital before her condition started improving, although she still deals with lasting hearing loss and PTSD from the ordeal. While serious side effects are extremely rare, both drugs carry the risk of triggering a severe cutaneous adverse reaction – such as SJS according to The National Institute for Health and Care Excellence. At first, Heron appeared to be responding well to medication, until a pinprick-like rash appeared in May. I knew right away that it was an allergic reaction, and so I took her to the doctor and asked them to change the medication she was on.

Determining The Degree Of Hearing Loss
How does someone know what degree of hearing loss they have at different frequencies of sound? The best way to find out is to get your hearing checked by a trained audiologist or medical professional. The results of this hearing test will be shown on an audiogram like this one:
In this example audiogram, you can see that the person has a mild hearing loss in the low frequencies that becomes a profound hearing loss in the high frequencies. Typically a person with this hearing loss will be able to hear dogs barking, but not the ringing of a doorbell.
Hearing Impairment In Toddlers And Children
These signs might become more evident in slightly older children:
- The child is behind others the same age in oral communication.
- The child keeps saying âWhat?â or âPardon?â
- The child talks in a very loud voice, and tends to produce louder-than-normal noises.
- When the child speaks, their utterances are not clear.

Causes Of Hearing Loss And Deafness
Although these factors can be encountered at different periods across the life span, individuals are most susceptible to their effects during critical periods in life.
- Genetic factors – Include hereditary and non-hereditary hearing loss
- Intrauterine infections such as rubella and cytomegalovirus infection
- Birth asphyxia (a lack of oxygen at the time of birth
- Low-birth weight
- Other perinatal morbidities and their management
Childhood and adolescence
- Chronic ear infections
- Collection of fluid in the ear
- Meningitis and other infections
Factors across the life span
- Cerumen impaction
- Trauma to the ear or head
- Loud noise/loud sounds
- Viral infections and other ear conditions
- Delayed onset or progressive genetic hearing loss
The Difference Between Deaf And Hard Of Hearing
In medical terms, hearing loss is defined by the results of a hearing test. There are different levels that have been set to classify someone as either deaf or hard of hearing.
A complete hearing test will examine how loud sounds across the frequency range have to be in order for you to be able to detect them. It will also determine how well you are able to understand speech.
If you are not able to detect sounds that are quieter than 90 decibels hearing level, then you would be considered to have a profound hearing loss for those frequencies. If the average of the frequencies at 500Hz, 1000Hz, and 2000 Hz is 90dB or higher, the person is considered deaf. Someone that is hard of hearing can have a range of hearing loss from mild to severe.

How To Treat Sensorineural Hearing Loss
People with sensorineural hearing loss cannot regain their hearing, but most people can benefit from hearing aids. A more severe or profound sensorineural hearing loss can be treated with hearing implants. A few cases of sensorineural hearing loss can be treated by means of surgery.
A hearing test carried out by a hearing professional will detect if you have a sensorineural hearing loss.
Is Sensorineural Hearing Loss Permanent
Yes, unfortunately a sensorineural hearing loss is permanent as the hair cell in the inner ear cannot be repaired or replaced. And regardless of whether it is a bilateral or unilateral hearing loss the hearing does not recover fully or partly over time or by itself. The hearing that is lost is lost permanently. An age-related hearing loss, for example, typically worsens over time.
Can a sensorineural hearing loss be cured? In most cases unfortunately not. A sensorineural hearing loss is normally treated with hearing aids or hearing implants. Certain types of sudden sensorineural hearing losses can in some cases be cured but here it is important to seek medical help immediately.
