The design of a panel with lower weight and high stiness for passive noise control application is a quite challenging task. Generally, more mass per unit area is required to get high transmission loss at mid and lower frequencies. Transmission loss at lower frequencies can be improved by higher stiness and damping. A well-known solution in structural design community for higher stiness to weight ratio is honeycomb structure. It motivates us to conduct acoustical experiment on a natural honeybee hive. The experimental results are quite encouraging to mimic in practical applications. Theoretical models have been proposed to explain the acoustical performance of the honeybee hive. Design parameters of a hive like shape of the cell, number of layers, wall thickness and cell size have considered for parametric studies. Three dierent hypothesis have proposed to under- stand the acoustical performance of the hive. A simplied analytical expression has developed and corroborated with experimental results.
