Paper Abstract

In this presentation, fibers with 2 and 3 layers of coatings are made and their sound sensitivities are tested. It’s found that the interface between coating layers could weaken the acoustic transmission, and the acoustic impedance is mainly due to the difference of coating material’s density and velocity of sound. The fiber with 1.0mm diameter has the highest sound sensitivity of about 6×10-12/dyn/cm2 when commercially available coating material used. This paper also discusses the method of testing, including how to process the fiber and how to wind fiber. In the end of this contribution, some coating materials and coating diameters are compared.
