Towards improved measurements of bone conduction auditory brainstem responses in infants and adults: mitigation of stimulus artefact.

Objective: To reduce the amplitude of stimulus artefacts present in bone conduction auditory brainstem response (BC ABR) measurements.

Design: Electromagnetic shielding was applied to the surface of a clinical BC transducer. A foam pad was also placed on the shielded mastoid-contacting plate of the transducer.
