Pediatric Hearing Evaluations:
We test the hearing of newborns through adolescence with a variety of testing techniques. Testing usually takes 30-60 minutes per child.
- Otoacoustic Emissions (OAE) is used for newborns through adulthood. OAE is an electroacoustic test which measures the function of the outer hair cells (integrity of the cochlea). A small insert earphone is placed in the ear through which sounds will be played. Responses from the cochlea are measured to determine the child’s hearing levels.
- Visual Response Audiometry (VRA) is used for children 7-24 months of age. The child will sit on the adult’s lap between two speakers or wearing headphones. The audiologist will present sounds. The child will be taught to turn their head in response to the sound and will be rewarded with a toy that lights up. The child’s attention will then be brought back to center and the sequence will start again. Different pitches (frequencies) and loudness (intensity) will be used to determine the child’s hearing levels.
- Conditioned Play Audiometry (CPA) is used for children 3-6 years of age. The child will wear headphones or insert earphones and will be taught to place a block or other toy in a bin in response to the sound. Different pitches (frequencies) and loudness (intensity) will be used to determine the child’s hearing levels.
- Conventional Audiometry (CA) is used for children who no longer need conditioning tasks. The patient responds to auditory stimuli by raising their hand. Different pitches (frequencies) and loudness (intensity) will be used to determine the patient’s hearing levels.
- Basic Immitance Test Battery. These tests measure how the eardrum responds to sound. They provide information about the status of the middle ear, such as the detection of fluid in the middle ear or any perforation of the eardrum.
- Auditory Processing Disorders (APD) Testing. An auditory processing disorder is the inability or impaired ability to recognize or comprehend information by hearing even though a person has normal intelligence and normal hearing sensitivity. The auditory processing test battery consists of a series of auditory tests designed to measure processes such as phonemic decoding, dichotic listening, binaural integration, auditory closure and temporal patterning. APD testing is often recommended for school-aged children who have difficulty learning and listening. An APD evaluation assesses the auditory perceptual skills as they relate to communication and academic performance. Based on test results, our audiologist will recommend the appropriate follow up testing and/or therapy.
