VEMP using a new low-frequency bone conduction transducer

Abstract: ObjectiveA new prototype bone conduction (BC) transducer B250, with an emphasized low-frequency response, is evaluated in vestibular evoked myogenic potential (VEMP) investigations. The aim was to compare cervical (cVEMP) and ocular (oVEMP) responses using tone bursts at 250 and 500 Hz with BC stimulation using the B250 and the conventional B81 transducer and by using air conduction (AC) stimulation.MethodsThree normal subjects were investigated in a pilot study. BC stimulation was applied to the mastoids in c… Show more

“…Other types of bone conduction devices are available; these are named as "active transcutaneous" devices (or "direct bone drive devices with implanted transducer") and "passive transcutaneous" devices (or "over skin drive devices with implanted retention magnet"), both of which leave the skin intact; for a review, see Reinfeldt et al 2015 1 and Håkansson et al 2019. 2 Furthermore, bone conduction transducers are also used in consumer products, with the intention of being applied over intact skin, such as in headsets, speech training systems, and for diagnoses of hearing and vertigo (Fredén Jansson et al 2015, 3 Håkansson et al 2018 4 ).…”

“…diagnostics. Diagnostic transducers for bone conduction hearing testing (such as the B81) and for vestibular testing (such as B250 as proposed by Håkansson et al 2018 4 ) are calibrated using an artificial mastoid B&K4930 from Bruel & Kjaer, having an intact skin pad as load. For direct bone drive devices, a skull simulator is needed that in some way simulates the skull impedance.…”

“…The B71 conventional bone conduction transducer (RadioEar) was tried as an alternative. However, the output of the B71 is not always sufficient to for measuring oVEMP responses (5). A new bone conduction transducer, the B81 (RadioEar), has recently become available.…”
