Factors Related to Bone Conduction Reliability

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…As the force of the vibrator to head coupling is increased. less energy is needed to obtain threshold levels by bone conduction (Dirks, 1964). Harris et al (1953) observed that there are changes in hearing threshold with increased coupling force from 100 to 400 g. Further, Harris et al's (1953) results suggested little shift in threshold with increased coupling force above 400 g. Konig (1957), as well, noted changes in threshold with varying coupling force less than 750 g. However.…”

“…Standard bone-conduction vibrator placement should allow mastoid or forehead placement with proper force applied (American National Standards Institute, 2004b;Dirks, 1964). The test ear should never be covered for standard bone-conduction measurements.…”
