Air--conduction (AC) and bone-conduction (BC) thresholds were measured to evaluate standard reference thresholds and recommend revisions to audiometer standards. AC and BC thresholds were measured from listeners with normal hearing (NH) and sensorineural hearing loss (SNHL) at three sites. NH participants (n = 53) were selected based on age (18 – 25 years), normal AC thresholds, tympanometry, otoscopy, and absence of otologic disease. SNHL participants (n = 49) were selected based on AC thresholds, tympanometry, otoscopy, and absence of otologic disease. AC thresholds obtained from NH listeners averaged 3.7 dB HL. Air bone gaps (ABGs) occurred in NH and SNHL listeners above 2000 Hz and SNHL listeners at 250 Hz. Corrections to standard RETSPLs are recommended. ABGs in listeners without conductive pathology result from incorrect reference threshold levels for frequencies above 2000 Hz. False air-bone gaps increase with hearing-loss magnitude, probably due to effects of ambient and internal noise for low-level bone-conduction stimuli. False ABGs place patients at risk for unnecessary medical and surgical intervention. Reference threshold levels should achieve two objectives: 1) AC thresholds from young NH listeners should average 0 dB HL; 2) ABGs from listeners with normal middle-ear function should average 0 dB.
