Context 1
... a, b are sides of the membrane and v is the velocity of sound through the membrane . We calculated the frequencies and the frequency ratio of modes of rectangular membrane and the results obtained are given in Table 1. For the calculation, the sides are chosen to be a = 0.08m and b = 0.1m. ...
Context 2
... radius of the membrane is chosen as a = 0.08m for calculation. The obtained values are given in Table 3. From the Table 1, 2 and 3 the ratio of frequencies of different membrane gives some important insights. They are: ...
