Bone Conduction Audiometry

Bone conduction is a old time-tested procedure for confirmation of the degree of conduction hearing loss. Two creative approaches for estimating bone conduction hearing thresholds (sensory hearing levels) are described in an article and two PPT presentations here. One PPT presentation reviews an old but rarely used procedure, the sensorineural acuity level (SAL). There is also an article and PPT presentation about bone conduction ABR. For a somewhat heretical discussion of bone conduction (Hint: it's not always needed or worth the test time), you should read the Page Ten article Audiology Students Ask the Darndest Questions!. With regular application of two important objective auditory procedures (acoustic immittance measures and otoacoustic emissions), and confirmation of normal middle ear function, bone conduction audiometry doesn't make much sense.
