Hearing Screenings & Evaluations
Hearing screenings and evaluations are provided for children ages birth to 21. Testing procedures are determined by the student’s age and needs. Tests could include:
- Otoacoustic Emissions (OAEs) — A probe in the ear canal delivers auditory stimuli. The response is measured by a microphone in the probe tip, recording sounds made from outer hair cells in the cochlea.
- Pure Tone Air & Bone Conduction Threshold Tests — Tones of various pitches are presented to determine softest audible levels for each ear.
- Speech Detection/Reception Threshold Tests — Spondee words are presented to determine how softly speech can be heard in each ear.
- Speech Discrimination Tests — Words are presented from a standardized list to determine how clearly speech can be heard in each ear.
Middle Ear Analysis:
- Tympanometry and reflex testing determine the function of the middle ear mechanism.
Include one or more of the following: hearing aids, cochlear implant, and assistive listening devices.
- Made by SSD audiologists who are current on research trends and emerging technologies.
- Made based on the student’s hearing loss, hearing needs and available technologies.
- Aided sound field testing procedures verify real-world benefit received from the amplification devices.
- This testing also helps determine hearing aid, assistive listening device, and other hearing technology advantages for each student.
- Electroacoustic analysis of hearing aids and assistive listening devices determines how well the device is functioning.
- Real ear measurements verify the amplification is appropriate for the student, based on specific targets and hearing levels.
Possible Signs of Hearing Loss
A student may be experiencing hearing loss if he or she:
- Asks for frequent repetitions; says “what/huh” often.
- Turns the TV or radio volume louder than what others prefer.
- Seems to hear better on some days than others.
- Appears inattentive at home and/or school.
- Watches faces when someone is talking; turns head so that one ear is facing the sound source.
- Has delayed language or speech skills.
- Responds to a question with an unrelated answer.
- Has risk factors including (but not limited to):
- Family history of hearing loss
- Very low birth weight
- Assisted ventilation (for more than 10 days after birth)
- Severe jaundice after birth
- Head trauma
- History of ear infections
- Known syndromes
