Tuning Fork Tests
This article reviews the history of tuning fork tests, its current status as a clinical examination tool. All the commonly performed tuning fork tests are discussed in detail. The three commonly performed tuning fork tests include: Rinne test, weber test and Absolute bone conduction test.
متن کاملTuning fork shear-force feedback.
Investigations have been performed on the dynamics of a distance regulation system based on an oscillating probe at resonance. This was examined at a tuning fork shear-force feedback system, which is used as a distance control mechanism in near-field scanning optical microscopy. In this form of microscopy, a tapered optical fiber is attached to the tuning fork and scanned over the sample surfac...
متن کاملIntroduction to the quartz tuning fork
We discuss various aspects of the quartz tuning fork, ranging from its original purpose as a high quality factor resonator for use as a stable frequency reference, to more exotic applications in sensing and scanning probe microscopy. We show experimentally how to tune the quality factor by injecting energy in phase with the current at resonance quality factor increase or out of phase quality fa...

the site of the placenta. Administration ofanti-D immunoglobulin is routine after invasive procedures in Rh negative patients but is not appropriate for those already sensitised, in whom it would be ineffective.'5 In patients undergoing intra-uterine transfusions, however, fetomaternal haemorrhage may enhance maternal sensitisation. Not only might the disease be worsened in a subsequent pregnan...
متن کاملThe otologist's tuning fork examination--are you striking it correctly?
OBJECTIVE To determine if the manner in which a tuning fork is activated affects its vibrational response. STUDY DESIGN Diagnostic test assessment. SETTING Hearing Center of Excellence laboratory. SUBJECTS AND METHODS A Polytec OFV-5000 scanning vibrometer was used to measure the vibrational response of 256-Hz, 512-Hz, and 1024-Hz tuning forks after activation. The tuning forks were activ...
