sensorineural acuity level test

Indications

• hearing loss

Procedure

• indirect technique for estimating the sensorineural component of hearing loss
• each of the patient's airway conduction thresholds are tested twice
• the first threshold is measured in the quiet, the second is measured with vibration applied to the frontal bone
• quiet thresholds in patients with hearing loss are higher than those for normal people
• under conditions of vibration, thresholds for patients with conductive sensorineural hearing loss may be similar to that of controls; threshold may be twice as high with conductive hearing loss
• thus conductive hearing loss causes larger differences in the thresholds than sensorineural hearing loss

More general terms

• hearing evaluation
