Edgar Alvarado Anell, B. I. Arévalo Rivas

• We present a mathematical model to describe the dynamic of the tympanic membrane in the fixing of the ossicular chain. The model has been derived from the equation of free wave, considering first semi-membranes which resulting in nodal lines of center at the edge of membrane. Then we consider the case where only there is a nodal line, it which model the region where the malleus is connected to the membrane. Has been used MAPLE to perform simulations of model, have been observed the simulations of the tympanic membrane with the fixing of the ossicular chain. It shows the fixed region where the malleus is connected to the tympanic membrane.
