Laser Doppler vibrometry (LDV) measurements were performed on 5 Mongolian gerbils at multiple points along the manubrium of the malleus and along a line on the eardrum perpendicular to the manubrium, in order to study the spatial vibration patterns. A large hole was drilled in the bulia to equalize the pressures on the two sides of the eardrum, and to permit experimental steps to correct for temporal effects. The gerbil head is attached to a coupler with dental cement at the opening of the ear canal with an orientation that allows an optimal view of the eardrum. The measurement was performed inside a double-walled sound-proof room. Normalized displacements recorded along the manubrium showed the same frequency-response shape as on the pars tensa.Published
