Researching Characteristics of the Interaction between Sound Waves and Water Layers with Different Thickness

Abstract

Effects of water layers of different thickness and different frequencies of sound for sound transmission intensity have been analyzed by calculations of sound waves propagating in air and water layer. The results have showed that, when water layer thickness is less than 5mm, the changes of thickness have a powerful effect on sound waves, while it is more than 5mm, there is nearly no effect with different thickness, however, frequency of sound waves play a decisive role, especially when the sound wave frequency is less than 100Hz.
