Ultrasonic measurements of deer antler, bovine tibia and tympanic bulla.

Longitudinal sonic plesio-velocity, density and mineral volume fraction of the three bone types plus bovine bone matrix are reported. The axial sonic velocity in km/s and the mineral volume fraction for each is as follows: deer antler 3.08, 0.33; bovine tibia 3.89, 0.44; tympanic bulla 4.53, 0.85; bovine matrix 1.82. A brief discussion of the deer antler and tympanic bulla histology is included.
