Pediatric Hearing Test & Assessment

January 13, 2017

  • Pusat Alat Bantu Dengar Jakarta Hearing Center offers a broad range of testing and evaluation for infants, children and adolescents. These tests can assess whether sound is being conducted efficiently, or if there is damage to the inner ear or nerve pathways. We can also perform tests to determine if the brain is processing what your child is hearing.
  • We offer age-appropriate tests for infants and children. For infants, we use special physiologic testing that does not require a behavioral response from them. From about 6 months of age and older, behavioral testing can be conducted. The test process is safe, painless and fast- usually less than 30 minutes.

 

At Jakarta Hearing Center we provide the following full range of diagnostic hearing tests:

  • Play Audiometry (Audiometri Anak)
    • Ages: The difficult to screen child 3 years through school age.
    • Purpose: To obtain valid results with children when a hand-raising response to the stimulus is not effective.
    • Description: A modification of the standard pure tone screening procedure in which the child is conditioned to respond to the sound by placing a toy in a container. This replaces the hand-raising technique normally used.
    • Procedure: Place the headphones on the table facing the child with the audiometer set at 2000 Hz and the maximum level to insure the tone is audible.
    • Screener holds the toy near their own ear, assumes a “listening” attitude and present the tone. Indicate through facial expression that the sound was heard and then drops the toy in a pail. This may be repeated as often as necessary until the child shows interest.
    • Screener offers the toy to the child and places their hand on the child’s to guide the first responses. Encourage the child to wait until the sound is heard. When the child appears ready, present the sound and guide the child’s hand to put the toy in the container. Child may give consistent responses after only one demonstration or may need several to respond on their own. Demonstration first without and then with the headset on.
    • Reward the child with praise after the initial responses. If this is not effective, a tangible reward, like a sticker or food may be given.
    • Other: The response interval (tone or response time) varies between children. Some children will drop the toy as soon as the tone is heard, other will wait until the sound goes off before dropping the toy.
    • If the child does not accept the headset, the screener should try putting it on for only one or two seconds, remove and reward the child. The time with the headset on should be slowly increased.
    • A timid child will often benefit from watching one or two other children successfully complete the screening.
  • Pure Tone Audiometry (PTA) (Audiometri Nada Murni)
    • Ages: Adults and Children old enough to cooperate with test procedure (it relies on patient response)
    • Purpose: To determine the presence or absence of hearing loss. If hearing loss is present, the audiologist will be able to determine both type and degree of hearing loss.
    • Description: PTA is a subjective, behavioral measurement of hearing threshold, as it relies on patient response to pure tone stimuli.
    • Procedures: You will be seated in a soundproof room, with headphones on or in your ears, and a bone conduction headband on your head. Your professional hearing care will be seated on the outside of the sound booth and manipulate the audiometry equipment while testing your hearing.
    • There are two parts to this test:
      • Your professional hearing care will first test to see if you are able to hear a variety of different pitches. You will be asked to push a button or raise your hand when you hear the different tones.
      • This part of the test examines air conduction and bone conduction. Both the headphones for air conduction testing and the headband with the oscillator are placed behind your ear for bone conduction testing.
    • Your professional hearing care will compare the results of the two types of conduction to determine which part of auditory system is responsible for the loss.

  • Speech Audiometry (Audiometri Tutur)
    • Ages: Adult
    • Purpose: In conjunction with pure-tone audiometry, it can aid in determining the degree and type of hearing loss. It also provides information regarding discomfort or tolerance to speech stimuli and information on word recognition abilities.
    • Description: Information gained by speech audiometry will determine how softly you are able to hear words and the other will measure how clearly you are able to understand words.
    • Procedures: (5-10 minutes) You will be seated in the sound booth and will be wearing headphones.
      • Your professional hearing care will ask you to repeat a list of words to determine your Speech Reception Threshold (SRT) or how soft you were able to repeat common words.
      • Your professional hearing care will measure Speech Discrimination or Word Recognition ability. The professional hearing care will be either saying words to you or you will be listening to a CD recording. You will be asked to repeat the words. The professional hearing care then will be measuring your clarity or ability to understand speech.
