When a patient arrives at the clinic

Follow the stages of the assessment in order; each stop opens the related note, simulator and tool. Test order may vary by clinic and patient.

  1. 01

    History and otoscopy

    Listen to the complaint and examine the ear canal and eardrum.

    TermsTerm Cards
  2. 02

    Pure-tone and speech audiometry

    Air and bone conduction thresholds, masking and speech tests.

Case of the day

Read today’s audiogram

A new case every day. Answer three questions and see the reasoning straight away.

Preparing the case…

Right ear red, left ear blue. Air conduction O and X, bone conduction < and >. Masked bone conduction is shown as [ and ], masked air conduction inside a square.
