CHANNELLING YOUR CHILD’S HEARING SYSTEM FOR A BETTER FUTURE
Hearing screenings need to be provided to all the infants on birth. Those who could not pass the hearing screening test were further referred to pediatric audiologists.
Hearing screenings by Ear & Hear help in getting information regarding the child’s hearing system that is improperly responding.
- Visual Reinforcement Audiometry (VRA) for infants and toddlers of age 5 months to 2.5 years
- Conditioned Play Audiometry (CPA) for children of age between 2.5-4 years
Our Pediatric Audiology Mechanism
We have got well-trained audiologists that are qualified enough and know how to closely examine your child’s hearing and detect the hearing loss cases at their earliest, for prohibiting any language development gaps in your child. Accordingly, we provide appropriate sound amplification for your child and help to restore their hearing to normal.
Visual Reinforcement Audiometry (VRA)
- The child is placed at a high chair or on the parent’s lap.
- The attention of the child is kept towards the auditory stimuli.
- Animated toys are used with presentation of auditory signal during
the conditioning period.
- After conditioning, the toy is activated right after the child turns toward the signal.
- Signals are presented either through speakers or through foam
- The softest level of child’s response is recorded on the audiogram.
Conditioned Play Audiometry (CPA)
- The child is seated across from the test assistant
- The child is instructed to place a toy in some container whenever a sound is heard through a sound speaker or insert earphones.
- Initial sounds are presented well above the child’s expected thres hold to familiarize the child with the task.
- Child’s threshold is detected by presenting him progressively softer sounds.
- The threshold obtained may be a speech reception threshold (SRT) or speech awareness threshold (SAT), depending upon the willingness of the child to cooperate.
- SRT is the softest level at which the child can understand speech.
- The child may be asked to point to body parts, objects or pictures or to repeat two syllable words to obtain an SRT.
- SAT is the softest level of speech that the child can hear.
- SAT may be obtained by having the child respond to soft speech in the same way they respond to the tones for either conditioned play or VRA.
The results from this test may indicate the discontinuity of the ossicular chain, perforation in the ear drum, dysfunction of the Eustachian tube and the fluid in the middle ear.
Acoustic Reflex Thresholds
This test is conducted to measure the contraction in the middle ear’s stapedius muscle and how it responds to a loud sound. The muscle acts as a protection, dampening the sound effect before it reaches the hearing organ. The presence or absence of acoustic reflexes is a must during diagnosis of both central and peripheral auditory disorders.
Auditory Brainstem Response
This test is performed for determining the hearing loss in children who are either unable to respond, or too young to respond. It provides details regarding the intensity of sound that would be suitable for your child. However, it doesn’t provide information regarding what you child understands or hears. Normally this test is performed when your baby is sleeping and your child will be scheduled for two hours for the ABR to be completed.
Newborn Hearing Screening
This test measures the effectiveness of your child’s inner ear, known as cochlea. The outer hair cells of cochlea produced low level sounds interpreted as otoacoustic emissions that can either occur in response to clicks or tones, or spontaneously. Upon stimulation, they send information to brain and get a signal back, that is known as echo to the outer ear. This echo is then recorded and measured by the audiologist. These emissions are present in ears with normal functioning, but may be absent among those suffering from hearing loss.
