Reducing industrial noise emission utilizing jacketed pipe insulation is critical to reducing noise in industrial spaces. The ISO 15665 standard defines a testing process for measurement of the acoustical performance of installed and jacketed pipe insulation systems. However, the cost of testing per this standard, especially when using an external laboratory, can be very costly. That makes the development of a model to accurately estimate the performance of single, and multilayered, jacketed pipe insulation highly desirable. Utilizing a one-dimensional theoretical acoustic model along with empirical data, a model with sufficient accuracy to provide insertion loss results relative to the ISO 15665 standard was created. The creation and resulting functionality of the model for determining jacketed pipe insulation insertion loss and comparison of the resulting data to test results will be discussed herein.
