Audiograms Flashcards
1
Q
what are they
A
the first-line investigation that is performed when a patient complains of hearing difficulties.
2
Q
how to interpret?
A
anything above the 20dB line is essentially normal (marked in green on the audiogram below)
in sensorineural hearing loss both air and bone conduction are impaired
in conductive hearing loss only air conduction is impaired
in mixed hearing loss both air and bone conduction are impaired, with air conduction often being ‘worse’ than bone
