The audiogram is one of the most powerful tests in health care. It is one of the few that can lead to a diagnosis on its own. Bone-conduction testing gives the audiogram its diagnostic power. Bone-conduction audiometry requires calibration methods that are expensive, cumbersome, and often misunderstood.

Journal of Bioelectricity, 1982
A new five-point electrode method was used to measure the conduction properties of rabbit femur. The two outer electrodes introduced current into the bone while the three inner electrodes (1 cm apart) were used to measure potential drop. Measurements were conducted at 20-7,000 hz for voltages of 0.1-1.2 volts.

Speech Audiometry by Bone Conduction
Archives of Otolaryngology - Head and Neck Surgery, 1955The importance of the use of speech audiometry by air conduction in conjunction with pure tone tests in the diagnosis and evaluation of hypacusis is unquestioned in the field of otology. Each method contributes uniquely to a fuller understanding of a particular case of hearing impairment.

Bone Conduction Calibration: Current Status
Journal of Speech and Hearing Disorders, 1979Attempts to specify normal threshold sensitivity by bone conduction have been unsuccessful because of problems in obtaining reliable measurements from commercially available artificial mastoids. Recent design modifications incorporated in the Bruel and Kjaer 4930 artificial mastoids have resulted in greater uniformity among these units.

Lateralization of bone-conducted sounds
American Journal of Otolaryngology, 1982Lateralization of bilaterally applied bone-conducted signals could be accomplished by variation of time (delta t) or intensity (delta I) differences between signals. The task was relatively easy with clicks and with tone pips with short rise times. When rise times were made longer than 1 msec the ability to localize deteriorated, indicating that it ...

A bone-conduction handset less causing howling even when an output is increased since the isolation of a speaker unit from a handset body is sufficient, less leaking sound, and providing excellent use feeling. In the handset, a bone-conduction speaker unit (3) is mounted on the handset body (1) through a speaker mounting member (2) made of a ...

Bone-Conducted Stimulation in Electrocochleography
Acta Oto-Laryngologica, 1977The mechanical vibration patterns close to the cochlea in intact skulls of human cadavers have been studied by means of a miniature accelerometer. A Radioear B70A vibrator and a Brüel & Kjaer Mini Shaker have been used, fed with filtered clicks and with short tone bursts.

Bone‐Conduction Electrocochleography: Clinical Applications
The Laryngoscope, 1978Cases are presented which show the clinical utility of recording an electrocochleographic response to bone‐conducted stimuli. The procedure is fraught with problems of acoustic control and artifact generation, but has distinct although limited value in clarifying masking dilemmas in patients with bilateral hearing loss.

Bone Conduction Thresholds without Bone Vibrator Application Force
Journal of the American Academy of Audiology, 2015Background:Osseous bone conduction (BC) stimulation involves applying the clinical bone vibrator with an application force of about 5 Newton (N) to the skin over the cranial vault of skull bone (e.g., mastoid, forehead). In nonosseous BC (also called soft tissue conduction), the bone vibrator elicits hearing when it is applied to skin sites not over ...
