“…SEA model is presented here by considering only the resonant power transmission of acoustic noise source between all the subsystems. Lyon (Lyon, 1967) reported that the relative roles of resonant and non-resonant transmission can be evaluated by considering the structural damping of the structure. Pope (Pope, 1971) stated the fact that large, thin, and heavily damped systems tend to transmit in a nonresonant manner.…”

“…In the present analysis, the resonant transmission is considered significant compared to nonresonant transmission because of lightly damped enclosure panels. Hence, to reduce the complexity of the model and based on the literature (Eichler, 1965;Lyon, 1963Lyon, , 1967Manning, 1968;Hillarby, 1991a, 1991b;Pope, 1971;Renji et al, 2001), the non-resonant transmission is not considered in the current analytical model.…”

The conical shape structures are widely employed in many practical applications such as aircraft, rockets, tanks, and submarines. Prediction of sound transmission loss is often required at the design and evaluation stages of such structures. In this paper, an analytical model is proposed using the statistical energy analysis (SEA) technique to predict the sound transmission loss of a conical shape acoustic enclosure in a broad frequency range. The proposed model is verified experimentally using the sound intensity experimental technique. It was found that the analytical predictions are in good agreement with the measured transmission loss, specifically at the ring and critical frequencies. The percentage error between predicted and measured lower ring frequency is 5.1% and that for the upper ring frequency is 0.4%. The percentage error between predicted and measured critical frequency is 2.7%. The results obtained indicate that the developed analytical model can be used as an efficient design tool to predict the acoustic performance of conical shape structures.
