Acoustic Transmission Factor through the Rat Skull as a Function of Body Mass, Frequency and Position

In this study, we measured acoustic transmission factors through 13 excised skulls of male Sprague-Dawley rats weighing between 90 and 520 g, at different positions on each skull and at 1, 1.25, 1.5, 1.75 and 2 MHz. Our results revealed that insertion loss through rat skull increases linearly with both body mass and frequency and strongly depends on the position, decreasing from the front to the back and from the midline to the lateral sides.
