Hearing Loss

Living in the city, we are constantly bombarded by different kinds of noises. Did you know that listening to loud music during our daily commute is enough to cause damage to our ears? And the scary thing is that we rarely know the extent of damage to our hearing until it is already too late.

At the beginning, you may hear a ringing sound in your head/ears. However, this is already a sign of hearing loss.

Take care of your hearing and protect your ears. What is hearing loss? Are hearing aids helpful? We hope that this website will have all the answers to your questions.

Audiological Assessment

  • Age 6-30 months
    • Visual Reinforcement Audiometry: The child is conditioned to turn his/her head towards a sound source every time they hear a sound. When he/she successfully locates the sound source, he/she is reward by lights and/or an animated toy. This test aims to determine the child’s hearing threshold at different frequencies.
  • Age 3-5 years old
    • Conditioned Play Audiometry: The child is taught to perform a simple task (e.g. put a toy into a bucket) every time they hear a sound. The test is conducted with headphones, to allow the child's hearing threshold at different frequencies to be tested in each ear.
  • Age 6 or above & Adults
    • Pure Tone Audiometry: This test consists of air and bone conducted measurements. Air conduction test evaluates the entire auditory pathway (the outer, middle & inner ear as well as the auditory nerve) using headphones. Bone conduction test evaluates the inner ear, bypassing the outer & middle ear. We obtain information about the hearing threshold and the type and degree of hearing loss with these two tests.

Tinnitus Assessment

Central Auditory Processing Disorders (CAPD)

  • What is CAPD?

CAPD (also known as APD) is an auditory deficit that affects the ability of the central nervous system to efficiently use auditory stimuli. CAPD is not a result of language, cognitive or related disorders (such as cognitive impairment and Attention Deficit/Hyperactivity Disorder [ADHD]). 

Individuals (children and adults) with CAPD have normal hearing, yet struggle to process the meaning of speech in certain scenarios. 

Common Symptoms and Behaviors 

The following are commonly reported but are not limited to: 

  • Difficulty understanding speech in noisy environments
  • Difficulty following complex verbal instructions
  • Difficulty discriminating similar speech sounds (e.g. /s/ vs /sh/)
  • Difficulty with sound localization
  • Difficulty remembering spoken information
  • Poor musical ability
  • Academic difficulties (especially subjects involving reading and spelling) 
  • Easily distracted
  • Often requests for repetition
  • Often provides inconsistent/inappropriate verbal responses

Assessment for CAPD Screening and Diagnosis

ENT Laser offers CAPD evaluation for school aged children with normal hearing between ages 5 to 12. The entire evaluation will comprise of 1-2 sessions, depending on the age, attention and ability of the child. 

Different tests will assess different auditory abilities (for example, the child’s ability to process speech in the presence of background noise, and ability to process speech when there are competing speech signals).

The evaluation will help the Audiologist determine whether the child has auditory processing disorder.

Intervention and Management 

Management programs are based on individual needs. In many circumstances, the use of assistive listening devices (such as FM systems) can be helpful in supporting the needs of a child who has CAPD. The Audiologists at ENT Laser will work closely with families and teachers continuously, to facilitate and maximize the learning potential of all CAPD children. 

Hearing Aid Prescription

  • About Hearing Loss
    • When an individual loses their hearing, their perception of sound becomes distorted and may start to speak loudly and have difficulty correcting their own pronunciation. These individuals may also isolate themselves from people and reject social activities as they cannot communicate properly. Therefore it is important that people with hearing impairment get hearing aids as soon as permanent hearing loss is diagnosed.
  • Types of Hearing Aid
    • Behind-the-ear (BTE) Hearing Aids: BTE hearing aids are worn behind the ear with a tube running down the front of the ear attached to an earmold that is plugged into the canal of the ears. These hearing aids are a little bigger in size and are suitable for those who have a severe to profound hearing loss.
    • In-the-ear (ITE, ITC, CIC) Hearing Aids: ITE hearing aids are even smaller than BTE hearing aids. There are 3 different sizes; in-the-ear (ITE), in-the-canal (ITC) and completely-in-canal (CIC). Some parts of the hearing aid are inside the ear canal; therefore, it is more hidden than the BTE. These hearing aids are suitable for those who have a less severe hearing loss.
    • Hearing Aids with an External Receiver: The invention of external receivers greatly reduced the size of BTE hearing aids. Like BTE hearing aids, these hearing aids are usually worn behind the ear, but the size of the machine is smaller, and a thin wire runs into the ear and the receiver is placed inside the canal. It is also more comfortable as the occlusion feeling is also less than the other types of hearing aids, yielding more natural input of sounds for the user. This type of hearing aid is suitable for those who have a high-frequency hearing loss.
  • Before selecting a hearing aid, the user should first consult an ENT specialist or a qualified Audiologist to check whether or not a hearing aid is necessary. Basic tests involve external auditory canal, eardrum and middle ear function examinations. If hearing loss is detected, the doctor will decide your next course of action. If medical and surgical treatments are helpless in correcting your hearing loss, then you may consider wearing hearing aids.
    • Hearing Aid Fitting Procedure
      1. Hearing Assessment – Conduct hearing tests to understand the extent and type of hearing loss.
      2. Selecting a Hearing Aid – A qualified audiologist will recommend an appropriate hearing aid for you based on the severity of your hearing loss, personal preference, ear shape, age, lifestyle and other external factors.
      3. Impression for Ear Moulds – After selecting a hearing aid, a qualified audiologist will make an ear impression, order a custom ear mould and a hearing aid outer case.
      4. Adjusting Hearing Aids – When the headset and ear mould are completed, a qualified audiologist will adjust the hearing aid to the optimal level according to the user’s needs and lifestyle. Then he or she will conduct a series of objective and subjective listening tests to assess the performance of the hearing aid. Lastly, the audiologist will explain the maintenance and correct usages of the hearing aid.
      5. Fine-tuning and Follow-up – Since each user leads a different lifestyle under a different environment, the audiologist will conduct a follow-up check a week after fitting. If necessary, the audiologist will fine-tune the hearing aid to the most appropriate and comfortable level for the user.

Swimming Ear Plugs

Contaminated water can easily enter the ear canal during swimming, causing inflammation of the ear or otitis media. People with chronic middle ear infections, eardrum perforations and grommets are recommended to wear swimming earplugs during water contact to prevent ear infections. There are two types of swimming earplugs; custom-made and conventional ready-to-wear types.
