Ivo Dobrev

Prior to 2009 the data available to characterize the function of the mammalian eardrum was rather limited and consisted of time-averaged holograms gathered 30 to 40 years previously or laser-vibrometer measurements usually made with low spatial density or over small regions of the eardrum. These few measurements could be compared to the plethora of Finite-Element models of eardrum and middle ear function. More recently, a collaboration between an optics group at the Center for Holographic Studies and Laser micro-mechaTronics at the Worcester Polytechnic Institute in Worcester MA and physiologists and acousticians at the Eaton-Peabody Laboratory at the Massachusetts Eye and …
