The following are the signs that suggest you may have a hearing loss:

  • You can’t hear the telephone or doorbell.
  • You frequently asked people to repeat what they say.
  • You have to play the TV or radio loudly.
  • You can hear voices when people are talking but cannot understand whey they say.

Hearing loss can be divided into four main types:

Conductive hearing loss Problem in the external or middle ear
Sensorineural hearing loss Problem in the inner ear
Mixed hearing loss Problem in both the middle and inner ear

Hearing loss is usually classified as follow:

Mild hearing loss 26 to 40 dBHL
Moderate hearing loss 41 to 55 dBHL
Moderately-severe hearing loss 56 to 70 dbHL
Severe hearing loss 71 to 90 dBHL
Profound hearing loss Greater than 91 dBHL

Otitis media is the most common cause of transient conductive loss in children. Otitis media is inflammation of the middle ear, which is caused primarily by Eustachian tube dysfunction. Certain groups appear to be more at risk for otitis media than others, e.g. children, people with cleft palate or other craniofacial anomalies etc.

Yes, hearing problem can be one of the causes for a slow speech development of a child. Good hearing sensitivity is important for children to learn speech accurately. If they have hearing problem, they may miss some information and find difficult to learn and pronounce speech. Of course, slow speech development can be also related to inattention, developmental or a real speech problem. Melody has speech therapists and audiologists who can assess speech and hearing abilities and make appropriate recommendations for your child, such as speech therapy or hearing aid fitting.

Yes, you can still hear, however, the sound s perceived will be softer. In general, if eardrum perforation causes a hearing loss, it will be a mild, conductive hearing loss. Eardrum perforation can be caused by trauma or secondary to a middle ear infection. Please consult an ENT (ear-nose-throat) doctor for more information.


Tinnitus is the term for buzzing, whistling or humming noises in the ears or head in the absence of “real” sound from outside. It may be continuous or intermittent, loud or soft. Although tinnitus can sometimes be very distressing, it is not life threatening, and the quality of your life can be recovered.

What causes tinnitus?

Many things are suspected or known to cause tinnitus or make it worse :

  • Noise exposure
  • Medicines such as anticancer drugs, antibiotics, antidepressants, etc.
  • Some viral infections e.g. measles
  • Head injuries
  • Ear infections and other ear disorders
  • The aging process
  • Stressful events
  • Any type of hearing loss

Tinnitus Retraining Therapy

In 1990, Dr. Pawel Jastreboff developed a neurophysiological model of tinnitus. He used this model to develop a method of treatment called Tinnitus Retraining Therapy (TRT), the latest and most successful treatment of tinnitus so far. This involves repeated counselin g, r elaxation training , use of hearing aids or low-level noise generators. Results after 18 months of TRT show that most people no longer find the tinnitus disturbing and more than a third of participants find that it disappears completely.

Four basic components of TRT:

  1. Complete audiological evaluation of tinnitus and hearing status.
  2. Medical evaluation to rule out any medical problem or treatable disease.
  3. Counselling to educate the patient and neutralize the negative emotions.
  4. Sound therapy to inhibit the tinnitus perception.
