Is hearing normal?2. What is the degree of hearing loss?3. What type of hearing loss is it?Hearing Assessment ProcedruesBehavioral MeasuresMeasures of hearing behavior dependent on the perceptions and cooperation of the listenerNonbehavioral MeasuresAcoustic or physiological responses recorded in association with an acoustic eventPure Tone AudiometryMajor behavioral auditory measureMeasurement of pure tone thresholds between 250-8000 HzAir conductionBone conductionPure Tone AudiometryThe results of PTA tell us1. Air conduction thresholds across frequency tells us if hearing is normal or not2. If hearing by air conduction is NOT normal, the thresholds tell us the degree of hearing lossAverage Air Conduction Threshold and the Degree of Hearing LossPure Tone AudiometryThe results of PTA tell us1. Hearing by air conduction across frequency in each ear tells us if hearing is normal or not2. If hearing by air conduction is NOT normal, the thresholds tell us the degree of hearing loss3. Differences between hearing by air conduction and hearing by bone conduction tell us the type of hearing lossAir Conduction vs Bone Conduction TestingnAir conduction tests the entire auditory system. Bone conduction bypasses the conductive mechanism, so it tests only the inner ear.The AudiogramWhat the Audiogram Says About the ImpairmentWithin normal limitsMild ModerateSevereProfound/deafDetermining the Type of Hearing LossWhat the Audiogram Says About the ImpairmentThe degree of hearing lossThe configuration of the hearing lossThe type of hearing lossConductiveSensorineuralMixedSpeech AudiometryAnother behavioral measure of auditory abilitySpeech thresholdsSpeech Reception thresholdSpeech Awareness thresholdWord recognition testingIdentifying Hearing Loss Through the First YearCommunication checklistsParents’ reportsCase historyInformal observationFormal testingVisual Reinforcement AudiometryBehavioral Observation AudiometrySound Field Arrangement for VRATypical Response Levels to Sounds from Birth-2 yearsNonbehavioral Measures of HearingAuditory brainstem evoked response (ABER)Nonbehavioral Measures of HearingOtoacoustic
