Submarines are often covered with resonant sound absorbers known as anechoic coatings or tiles in order to avoid detection by sonar. A simulation-based model is developed for predicting the acoustic properties of underwater anechoic structures having matrix viscoelastic materials containing air-filled cavities. | Effects of air-filled cavity distribution on acoustic absorption performance of anechoic coatings
