Screening protocols It is possible to create a screening protocol in the DPOAE module that provides a test outcome labelled as PASS, REFER or INCOMPLETE. The application of DPOAEs in screening is ver…
This video provides a demonstration of 4 kHz NB CE-Chirp® ABR testing via bone conduction on a 4-week-old baby. Her air conduction (insert earphones) results at the same frequency indicated satisfact…
Air-bone gaps are the difference in sensitivity threshold between air and bone conduction transducers. This measurement helps distinguish between conductive and sensorineural hearing losses, as well…
The Carhart notch is a notch in a bone conduction audiogram of more than 2 kHz, and was first described by Raymond Carhart, Ph.D., in 1950. Explanation Stimulation of the ear via bone conducted vibra…
