The thyroid gland, one of the largest endocrine glands, is investigated as a resonant cavity forming a means of storing energy at a particular frequency with a small bandwidth. A number of 16 acoustic frequencies are evaluated for a geometric model of thyroid gland, by using finite element method. The spatial distribution of the extreme values of acoustic pressure is in accordance with blood supplier positions. The decrease of blood supplier efficiency and local temperature is argued when certain objects appear inside, like nodule or cysts, by showing the new spectral signatures and their special positions.
