Method
• Groups– 6-year-old children – 60-year-old adults
• Audiogram Selection Criteria– Right ear thresholds only– Thresholds for each octave test frequency
(250-8000 Hz)– At least one threshold > 30 dB HL– Confirmed sensorinueral hearing loss by bone
conduction audiometry– Air-bone gaps < 10 dB

Method
• Core Set of Audiograms– 227 children– 248 adults
• Analyses– Configuration– Asymmetry – Progression

Summary
• Configuration– Children had a wider variety of
audiometric configurations
• Asymmetry – More children had asymmetric losses and
those asymmetries were more severe
• Progression/Fluctuation– Thresholds increased and decreased on
subsequent audiograms
