Audiometry Student Health & Human Services Travels to schools Screens hearing Refers to audiology (ARU) as needed Audiology Division of Special Education Works in a permanent sound booth Provides comprehensive evaluation of hearing Refers to DHH as needed LAUSD System: Audiometry and Audiology
LAUSD System: Audiometry and Audiology • Audiometrists go to schools and screen the hearing of students • Ifthe student fails this hearing screening… • She/he may be referred for a more comprehensive audiological evaluation by an Educational Audiologist in a sound room (at the ARU)
Types of Hearing Loss • Conductive • Usually not permanent • Often treated medically • Left untreated, loss may become permanent • Affects outer and middle ear
Types of Hearing Loss • Sensorineural • Permanent hearing loss • Affects inner ear (sensory), and/or • Auditory nerve (neural)
Sensorineural loss = problem with inner ear (cochlea) and/or nerve
Types of Hearing Loss • Mixed Hearing Loss: combination of • sensorineural (permanent) AND • conductive (usually temporary)
Mixed loss Problem in outer and/or middle ear along with problem with inner ear and/or nerve
Degrees of Hearing Loss • Normal Hearing ~ 0-15 decibels • Minimal (Borderline) ~ 16-25 decibels • Mild ~ 26-40 decibels • Moderate ~ 41-70 decibels • Severe ~ 71-90 decibels • Profound ~91+ decibels
Audiogram (graph of hearing status) low pitchhigh pitch (FREQUENCY) soft = RIGHT EAR threshold of hearing (DECIBELS) = LEFT EAR threshold of hearing loud
Frequency (pitch) Low pitch High pitch soft Loudness (decibels) Average conversational speech level loud
= RIGHT EAR (Remember red/round = RIGHT) • Student can hear sounds BELOW the line • Student will have difficulty hearing sounds above the line
= LEFT EAR • Student can hear sounds BELOW the line • Student will have difficulty hearing sounds above the line
= RIGHT EAR = LEFT EAR You may see both ears on the same audiogram This audiogram indicates a mild to moderate loss in the rightear and a moderate to profound loss in the left ear.
Educational Implications of Normal Hearing • Child detects complete speech signal even at soft conversational level • Good hearing does not preclude auditory processing problems
Educational Implications of Minimal (Borderline) Loss Child with a cold or the consistent mouth breather… • May have difficulty hearing • Faint or distant speech • At a distance • If classroom is noisy • May miss portions of fast-paced interactions • May fatigue more easily because of listening effort
Educational Implications of Fluctuating (conductive) Loss • Hearing ability may change daily • Typical of listening with fluid behind eardrum • Can “hear” but misses fragments of the message • May be accused of “daydreaming” or “not paying attention” • Speech and listening/attention skills may be affected if child experiences chronic fluctuating hearing acuity before age 7 years
Educational Implications of Mild Loss • Degree of difficulty experienced depends on • Noise level in classroom • Distance from teacher (speaker) • Configuration of hearing loss • May miss portions of fast-paced interactions and classroom discussions • Student often accused of • Not paying attention • Hearing when s/he wants to • Increased fatigue from listening effort
Educational Implications of Moderate Loss • Difficulty understanding conversational speech at a distance of 3 feet • Needs face to face communication • Needs structure and vocabulary controlled • Communication characterized by • Delayed receptive and expressive language • Limited vocabulary • Articulation errors
Educational Implications of Moderate-Severe Loss • Communication significantly affected • Marked difficulty in verbal communication in both one to one and group situations • Social interaction is increasingly difficult • Communication may be characterized by • Delayed receptive and expressive language • Limited vocabulary • Articulation errors • Possible impact on self-esteem
Educational Implications ofSevere Loss • May hear loud noises one foot from ear • If loss is pre-lingual in onset, oral language and speech may not develop spontaneously or will be severely delayed • If hearing loss is progressive or sudden, speech may deteriorate
Educational Implications of Profound Loss • Most students cannot depend solely on listening for communication access • Degree and configuration of loss will affect speech skills • If loss is pre-lingual in onset, oral language and speech will not develop spontaneously or will be severely delayed • If hearing loss is progressive or sudden, speech may deteriorate
Children with Hearing Loss Need …Our Help! • Early intense intervention is essential for receptive and expressive language development • Students need appropriate and consistent amplification for all their waking hours from an early age • Classroom acoustics need to be arranged to the student’s advantage… (think about things that make it easier for YOU to hear in a group situation)
Help for Students with Hearing Loss • Flexible/preferential classroom seating • Amplification/FM systems • Personal hearing aids • Personal FMs • Classroom speaker system • Personal speaker system • Acoustic modifications of classroom
Audiologic Resource Unit (ARU) Services • Provides audiologic evaluations for any child residing within the geographic boundaries of LAUSD, infant to age 22 • Educational Audiologists provide designated instruction and services (DIS) to Deaf and Hard of Hearing Special Day Programs to • Ensure properly functioning amplification systems • Support teacher in developing skills for use of residual hearing
Audiologic Resource Unit (ARU) Services • Provides resource to DHH Itinerant Program regarding • Residual hearing • Amplification systems • Provides counseling to parents regarding • Hearing loss • Amplification • Services and resources available to the student
Audiologic Resource Unit (ARU) Services • Provides professional development to District staff and outside agencies • Refers for possible assistance through California Children’s Services (CCS) for coverage of hearing aids and hearing health care services
Referral Process For Students with Suspected Hearing Loss • Begins with a referral to the ARU If... • Student fails hearing screening (at school, by Audiometry) OR • Student has an audiogram from outside facility OR • Student has known hearing loss OR • Parent/school requests audiologic evaluation

Referral Process for DHH Services • Based on the hearing evaluation, the ARU determines whether • Student has normal hearing, ending DHH referral process • Student’s hearing loss may adversely affect academic performance and/or access to the core curriculum, necessitating a referral to DHH for assessment to determine eligibility for DHH services
Referral Process for DHH Services • ARU will • Complete a report of each student tested • Complete page 1 of “Request for Special Education Assessment” and • ARU will mail the above to • School • DHH Office
Referral Process for DHH Services • School will: • In order to make sure all areas of parental concerns are addressed the school will assist parent in completing page 2 of Request for Special Education Assessment: “Student Information Questionnaire” • The school will generate Assessment Plan within 15 days, including all areas of suspected disability
Referral Process for DHH Services • School will • Check areas specific to DHH assessment • Academic-DHH assessor • Communication-DHH assessor and/or speech-language pathologist • Health-nurse/doctor • Send copy of signed Assessment Plan and Student Information Questionnaire to DHH Program, Beaudry-16th Floor
Referral Process for DHH Services • When signed Assessment Plan is received the DHH Assessor will contact school to arrange DHH Assessment to determine if • Hearing loss impacts access and progress in standards based core curriculum • Hearing loss impacts communication skills adversely affecting educational performance
Referral Process for DHH Services • Once all assessments are completed, school will • Contact all committee members • Schedule and complete IEP within 50 day time-line • Student’s eligibility, determination of services and placement will be discussed at the IEP Team Meeting
