3 Types Of Hearing Loss

Tuesday, October 31, 2017 8:45:37 PM Asia/Calcutta

The three main section of the ear are termed as the outer, middle and inner ear. The types of hearing loss is generally identified by detecting which section of the hearing pathway is affected. The identification of the affected section in the ear is very important in the determination of hearing loss and hearing loss treatment. Scroll on to know the 3 types of hearing loss.

Conductive Hearing Loss:

Sound waves originating from any source are initially received by the outer ear. Then, it reaches the middle ear. When hearing loss occurs due to the problems in outer or middle ear, it is termed as conductive hearing loss. Such problems mean that the hearing is not conducted properly through the outer or middle ear. Hence, this type of hearing loss is termed as conductive hearing loss. Generally, this type of hearing loss may be cured with proper medication. If not cured with the help of medication or surgery, patients with such problems can be benefited from using a hearing aid, because sound amplification is what that they need the most.

Sensorineural Hearing Loss:

After sound is conducted through the outer or middle ear, it reaches inner ear

(innermost part of the ear). When there is a damage in any part of the inner ear or auditory nerve that connects the inner ear

to the brain, hearing is hugely affected. Such problems can be termed as sensorineural hearing loss. Hearing loss due to disorder in cochlea area of inner ear is of sensory type and if concerning nerve disorders, then it is known as neural. Together it is known as sensorineural hearing loss. It is the most common type of hearing loss.

Though it is a permanent problem, hearing restoration is absolutely possible with the help of hearing aids.

Mixed Hearing loss:

A combination of both conductive and sensorineural hearing loss (problems in both outer/middle and inner ear) is termed as mixed hearing loss. Sometimes, if conductive hearing loss is neglected and left untreated for a longer period, this type of hearing loss occurs. Hearing aids or other hearing devices can help in hearing restoration for most of the patients suffering from this type of hearing loss.

Other types:

Pre-lingual or before learning language/speaking

Post-lingual or after learning language/speaking

Congenital hearing loss or present at birth

Acquired or hearing loss after birth due to one/more reasons

Hearing loss in one ear is termed as unilateral hearing loss

Hearing loss in both ears is termed as bilateral hearing loss

Pure Tone Audiometry (PTA): How It Helps?

Tuesday, October 31, 2017 8:40:19 PM Asia/Calcutta

Do you know about Pure Tone Audiometry (PTA)? How much and what we hear both determine the quality of our lives in many ways. Hearing is an important part of the entire communication process. Yet we often take how much we hear for granted. However hearing loss may often lead to isolation, frustration and even depression. This is why we must always pay sufficient attention to our ability to hear. Since the time wasted on account of hearing loss going unnoticed and undetected in the initial stages, may often prove to be critical in its treatment. So always be alert to this rapidly growing problem of hearing loss. You must be pay sufficient attention to any initial symptoms of hearing loss and visit a good audiologist who can detect any hearing disorders through Hearing Tests. One such very important Hearing test is Pure Tone Audiometry. We at Hearing Plus being the experts about treatment of hearing loss would try to provide you some basic information about the important Hearing Test of Pure Tone Audiometry (PTA).

What is Pure Tone Audiometry (PTA)?

Pure Tone Audiometry is a hearing test which is conducted by the Audiologist to determine the threshold levels of the hearing of an individual. The Pure Tone Audiometry (PTA) is therefore a hearing test which helps the audiologist in gain an insight into the type and the degree of the hearing loss patient. This hearing test is a subjective test where in the participation of the hearing loss patient is necessary. His or her responses are recorded against stimuli during the hearing test.

What To Expect During The Pure Tone Audiometry  (PTA) Test?

During the PTA test the hearing loss patient is placed in a soundproof room. He or she is made to wear head phones. The Audiologist, who generally sits outside the room, controls certain audiometric equipment and first exposes the patient to various types of pitches. The audiologist then tries to analyze whether the patient responds these pitches. The patient is made to respond by raising the hand or pressing a button for the indication. The latter part of the PTA test involves testing of the bone and air conduction in the ears. Both the head phones and head band with oscillators is put behind the patient’s ears to conduct this part of the test. The audiologist tests the results for both type of the conduction and then analyzes which part of the ear is damaged and needs attention.

A typical PTA test normally takes about 20- 25 minutes to be completed. The results of the tests are recorded in an Hearing Test equipment called the “Audiogram”. However as mentioned earlier, since the PTA test is a subjective hearing test, the response of the patient is very important in determining the correct findings from the test. Following the test the audiologist decides on the future course of treatment and what type of hearing device if needed would be suit to raise the hearing levels.

One important point to note about the PTA testing is that the standard of the equipment as well as the competence of the audiologist is of paramount importance for the test. We at Hearingplus being experts in Hearing loss treatment too carry out the PTA test.  For further queries please visit www.hearingplus.in

Treatment Of Hearing Loss In Children: Things You Need To Know

Tuesday, October 31, 2017 8:36:04 PM Asia/Calcutta

Hearing loss or hearing impairment is a condition when an individual loses his or her ability to hear sounds partially or totally in one or both the ears. The problem is generally considered to be a major one among adults and elderly. But, it is equally common among infants as well.

The loss of the ability to hear at the time of birth or after birth is becoming a common phenomenon to be seen and observed all around the globe. It is estimated that around a quarter or half of the profound or severe issues in hearing occurs due to genetic or hereditary causes. Before opting for the treatment of acoustic loss among children, get informed about the various types of loss of acoustic ability that occurs in the young ones and the reasons that are responsible for the same.

Types of Hearing Loss in Children:

A) Based on the age of onset of losing acoustic power, the loss of hearing can be -

  • Congenital Hearing Loss – which is present since birth
  • Acquired Hearing Loss – Acoustic issue occurs at any point of time during the developing years but is not present since birth.

B) Based on where the acoustic issues are located it can be of:

  • Conductive Hearing Loss – The loss of audiometric ability that occurs due to problems in outer and middle ear is called conductive acoustic issues.
  • Sensorineural Hearing Loss –Loss of audiometric ability that occurs due to a problem in inner ear is known as Sensorineural Loss. This kind of issue is permanent in nature.
  • Mixed Hearing Loss – Acoustic loss that occurs due to a problem in both outer or middle ear as well as inner ear.

Being a critical component to speech and language development, communication, literacy, and learning, hearing becomes mandatory for children. In absence of the ability of this sensory organ, it becomes extremely difficult for the children to cope up with the society and to deal with the regular educational curriculum followed by others.

Causes of Hearing Loss in Children

Loss of audiometric ability among children can be caused due to genetic, non-genetic factors and acquired factors.

Genetic Factor:

Genetic factors also known as the hereditary factors is considered to be the root cause of more than 50% of all acoustic issue caused among individuals. This hereditary problem at times shows its symptoms at birth itself and is also known for affecting the individuals in the later part of their life.

Most of the genetic loss can be described as autosomal recessive and autosomal dominant, some of the ways through which the trait or disorder passes down through families. Other, rare types of this audiometric loss include the X-linked (related to the sex chromosomes) or the mitochondrial inheritance patterns, which affects the individual’s life.

Nongenetic Factors:

The nongenetic factors account for about 25% of the loss of auditory. Some of the nongenetic factors that cause loss of acoustic ability among individuals include:

  • Premature birth
  • Maternal infections such as rubella, herpes simplex virus or cytomegalovirus
  • Injuries during birth
  • Low birth weight
  • Lack of oxygen or anoxia
  • Maternal diabetes
  • Toxemia during pregnancy
  • Toxins, including drugs and alcohol consumed by the mother during pregnancy
  • Inner ear malformations
  • Complications associated with the Rh factor in the blood/jaundice
  • Outer/ middle ear malformations (Atresia, stenosis)

Acquired Factors:

Acquired loss of audiometric power as the name suggest is acquired by the children at any point during their lifetime after their birth. The condition might be temporary or permanent. The conditions that causes acquired acoustic issues in children include:

  • Measles
  • Ear Infections
  • Noise Exposure
  • Chicken pox
  • Mumps
  • Ototoxic medications
  • Meningitis
  • Head Injury
  • Accident
  • Exposure to sudden outburst of noise
  • Encephalitis

Treatment of Hearing Loss in Children

Losing any sensory organ as a child does mean losing childhood permanently. It is thus recommended to take the child immediately to the specialist in a professional clinic in order to help them get treated as soon as possible. The treatment procedure might vary among children depending on several factors which include their type of audiometric loss, their age and the level of impairment.

The first step towards the treatment of hearing loss is the evaluation and diagnosis of the children, gauging their level of hearing impairment. The Hearing Loss in children can be treated through different ways, depending on their type of acoustic loss, level of impairment and age. The several ways of treatment includes:

Treatment of Hearing Loss through Hearing Aids

Joint Commission on Infant Hearing (JCIH, 2007) recommends children with suspected hearing loss should have their hearing loss confirmed by 3 months of age and that amplification in terms of hearing aids or cochlear implant should be fitted by 6 month of age. It thus helps overcoming the impact of hearing loss.

Best Suitable Hearing Aid For Children:

The Behind-The-Ear or BTE is the type of aid that is mostly recommended for the infants and the young children. The reason being as follows:

  •  BTE’s can fit in with various types of ear molds.
  •  Since ear molds are easily detachable from BTE’s they can be made again and again as the child grows.
  •  Also as the ear molds are easily detachable they can be cleaned easily.
  •  Parents can easily cross check the functionality of the hearing aid and can make necessary arrangements.
  •  BTE’s can accommodate wide variety of Hearing Loss.
  •  It can be easily connected with other listening devices like DAI and telecoil.
  •  Ear molds in BTE can be made of soft materials hence it is becomes very comfortable for children.

Hearing Aid Features:

The technological features which are essential and which makes the device extremely friendly for the children are:

  • Digital Noise Reduction
  • Directional Microphones
  • Frequency Lowering Strategies
  • Signal-Processing Features

Treatments of Hearing Loss through Cochlear Implants

A Cochlear implant is a medical electronic device that is used for replacing the function of the damaged inner ear. It bypasses the damaged hair cells of the inner ear and helps to provide sound signals to the brain.

When Is Cochlear Implants Suggested For Children?

The decision of using cochlear implant as the treatment of acoustic loss among children depends on the evaluation of their medical, audiological and psychological or habilitative condition. This treatment is used for children who suffer from:

  • Auditory Neuropathy/dyssynchrony
  • Bilateral Severe-to-profound sensorineural hearing loss
  • History of limited or no benefit from binaural hearing aids which are coupled with intensive auditory training
  • Absence of medical contraindications and other medical issues

Treatment of Hearing Loss through Hearing Assistive Technology: Personal FM Systems

Hearing Assistive Technology or HAT system is known for equipping the individual with the right kind of ability to overcome the negative consequences of the background noise and reverberation effect that interferes with the optimal audibility. Thus, improving the ability of the children to communicate and gain access to communication in adverse listening environments.

When Hearing Assistive Technology Is Suggested For Children?

When it comes to the use of HAT systems in children, the degree of audiometric loss is the major thing that is looked upon. Another factor that affects the selection of the children for the use of this system includes:

  • The degree of loss among the children
  • Situations such as hyperactivity, behavior, cognition and auditory issues
  • Technology issues
  • Ability to use the device and the financial resources

Treatments of Hearing Loss through Other Devices (Osseointegrated Devices, Auditory Brainstem Implants)

Osseointegrated Devices are considered for the children with the permanent bilateral, mixed and single-sided hearing loss. FDA has not approved the surgical implantations of bone-anchored aids in children within 5 years of age; however, they are permitted to wear the external processor until they are old enough for implantation.

Auditory Brainstem Implants is used and is recommended for the people who do not have a cochlea or auditory nerve. This implant helps in providing electrical stimulations of the cochlear nucleus in the brainstem.

Treatment of Hearing Loss through Pediatric Audiologic Re/Habilitation (AR)

The Pediatric Audiologic Re/habilitation (AR) therapy is provided for the children to help them improve their speech, language and communication skills and to develop a strong hold on their auditory behaviors. It enables the audiologists to use the varied form of communication methods which include the listening and spoken language, cued speech and language and sign language to help them with the right kind of modality of communication that they require.

Effective Hearing Loss Treatment to Heal Hearing Damage

Tuesday, October 31, 2017 8:33:10 PM Asia/Calcutta

The American Speech-Language-Hearing Association has stated that hearing loss is the third most common issue affecting the adults nowadays. Unfortunately, most of the sufferers refuse to treat it because they feel going to an audiologist is embarrassing.

Medical community has come up with several effective solutions. Some of the hearing loss treatment are described in detail in this blog. Are you ready to learn more?

Sensorineural Hear LossTreatment

Permanent hearing damage is mostly caused by sensorineural hearing loss. If you’re one of them, then the time has come when you should seek for a hearing aid.

When the inner cells of your ear get damaged, it results into sensorineural hearing issue. In case, the condition is not improved with the help of a hearing aid, you may need a cochlear implant.

Conductive Hear Loss Treatment

Building up of earwax overtime leads to conductive hear loss. This type of hearing damage is curable and is temporary. A perforated eardrum also sometimes leads to issues in hearing. Experts can help you immensely by finding out the cause and thus will suggest remedy accordingly.

People suffering from this problem can be treated with a medicine or surgery. However, your specialist is the only person to decide which type of treatment should be carried out.

If the condition has not taken a serious turn, antibiotics are prescribed to deal with ear infections. Many ear drops are also available to dissolve the earwax fully.

Role of Hearing Devices

Hearing aids assist the wearer to hear the sounds surrounding him or her. The sounds when they get in the device are then processed. Once the sound is amplified, it starts to release signals into the ear. Consequently, you will get a completely customized hearing experience.

A great majority of centres of hearing loss treatment in Kolkata offer both types of hearing aids namely, analog and digital.

Analogue Hearing Aids

Presently, analogue hearing aids are not much in use. It works by changing the intake sounds into electrical signals. These signals are then amplified by the device so as to feed them properly back into the wearer’s ear.

Many analogue hearing devices are designed in a way that they can distinguish a deafening noise from a tolerable one. Due to this advancement, it has gained the ability to decide which sound needs amplification.

Digital Hearing Aids

Digital hearing aids are manufactured to ensure quality hearing. Its automatic programmers eliminate the need to push a button to adjust the programs. These devices are more effective because it can completely eliminate the feedback of the environment.

Concluding Lines

Don’t expect that your auditory device will restore your hearing ability. Instead, it will improve your communication ability gradually by amplifying the sounds it has absorbed.

The medical advancements taking place almost every day has opened new ways of treating the hear loss if diagnosed early. It’s better not to delay visiting a hearing aid clinic in your locality in case you have issues with hearing.
