Document Summary
Audiogram: patients pure tone thresholds are recorded on this graph. Decibels of hearing level: (db hl) decibel scale in which the reference value is the minimum spl standards for normal hearing as a function of frequency, where 0db. Hl at any frequency represents the lowest level for normal hearing. Unmasked: without noise presented in the non test ear. Masked: with noise presented in the non test ear. Clinical masking: process of putting noise into the non test ear (nte) while measuring thresholds in the test ear. Masked thresholds: pure tone thresholds obtained in the te. *when describing pure tone audiogram, the following 3 types of info should be conveyed: Type of hearing loss: one of the parameters used in describing audiograms; type of loss can be either conductive, sensorineural, or mixed for any frequency. Sensorineural hearing loss: air bone gap equal or less than 10db.
