How to Measure Bone Conduction ABRs
Is it possible to measure ABRs via a bone anchored hearing aid?
The answer is yes.
Bone-anchored hearing system (BAHS) patients are typically those with a conductive (or mixed) or single-sided sensorineural deafness. Either of these two categories of patient can be tested either with conventional bone-conducted stimuli (e.g. through a Radioear B71 or B81 bone conductor), or their prosthetic device can be stimulated directly, and the evoked potential system merely measures the response (but does not provide the stimulus). This latter approach has some similarities to that of eABR (electrically evoked ABR) associated with cochlear implant patients.

After working for several years as an audiologist in the UK, Michael completed his Ph.D. in 2010 at The University of Manchester. The topic was plasticity of the human binaural auditory system. He then completed a 3-year post-doctoral research program that built directly on the underpinning work carried out during his Ph.D. In 2015, Michael joined the Interacoustics Academy, offering training and education in audiological and vestibular diagnostics worldwide. Michael now works for the University of Canterbury in Christchurch, New Zealand, exploring his research interests which include electrophysiological measurement of the central auditory system, and the development of clinical protocols and clinical techniques applied in areas such as paediatric audiology and vestibular assessment and management.
