Air and Bone Conduction Frequency-specific Auditory Brainstem Response in Children with Agenesis of the External Auditory Canal [PDF]
International Archives of Otorhinolaryngology, 2017 Introduction The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations.

Issues Concerning the Mechanisms of Bone Conduction
Audiology ResearchAir and bone conduction thresholds are used to differentiate between conductive and sensori-neural hearing losses because bone conduction is thought to bypass the conductive apparatus, directly activating the inner ear.

Comparison of umbo velocity in air- and bone-conduction [PDF]
Hearing Research, 2012 This study investigates the ossicular motion produced by bone-conducted (BC) sound in live human ears. Laser Doppler vibrometry was used to measure air conduction (AC)- and BC-induced umbo velocity (V(U)) in both ears of 10 subjects, 20 ears total. Sound pressure in the ear canal (P(EC)) was measured simultaneously. For air conduction, V(U) at standard

The thermal conductivity of air [PDF]
Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1919 Abstract The thermal conductivity, k, of a gas is connected with its specific heat, Cv, and its viscosity, η; by the relation k = fηCv. The numerical constant, f, in this relation can be deduced theoretically, and various values, which are given later, from 1·25 to 2·5 have been obtained according to the law of force assumed to act in

Cross hearing—air conduction or bone conduction [PDF]
Psychonomic Science, 1970 Unilaterally anacusic Ss were given pure-tone threshold tests in each ear, with and without the good ear plugged. The threshold shift produced by the plug was less for the bad ear than for the good ear. Since interaural attenuation was unaffected by the plug, it was concluded that cross-hearing occurs via bone conduction.
