Laser Doppler vibrometry (LDV) is an emerging technology for assessing middle ear (ME) function that detects the sound-induced velocity (Vu) of one of the ME bones, the malleus, over a wide frequency range (300 to 6000 Hz) using a reflected laser beam. The PI seeks to develop LDV measures as a new research area in line with his previous work in the assessment of ME function using wideband acoustic immittance (WAI) measurements. Because LDV measures the movement of one of the ossicles, it is inhe...
