The electrical impedance of the neck is measured by the device. As this impedance varies as the vocal folds vibrate, the output of the device is a signal analogous to the degree of vocal fold contact at a given instant. This waveform of impedance against time is known as Lx. Lx may be further processed to derive information about the duration of the <a href=\"http:\/\/blogjam.name\/sid\/?page_id=858\">period<\/a> of vocal fold vibration (Tx) and to measure instantaneous <a href=\"http:\/\/blogjam.name\/sid\/?page_id=1318\">fundamental frequency<\/a> (Fx).<\/p>\n<hr>\n<p><center><img src=\"lx_strobe.JPG\" alt=\"\" \/><br \/>A sequence of stroboscopic images of one cycle of vibration of the vocal folds aligned with the resulting Lx signal<\/center><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pronunciation GB: l\u0259\u02c8r\u026a\u014b\u0261\u0259\u0261r\u0251\u02d0f, GA: l\u0259\u02c8r\u026a\u014b\u0261\u0259\u0261r\u00e6f An electronic device for monitoring and analysing the vibratory activity of the vocal folds.
