Regarding the Case of a 1-Dimensional Tube with a Vibration Source and a Hole in It

Abstract

While research on automobile whistling and aspiration noise has been conducted in the past, we believe that understanding the properties of whistling and aspiration sounds using a 1-dimensional tube as a simple model is necessary in fields such as automobiles. Therefore, we discussed the case where there is a vibration source in a 1-dimensional tube with a hole. We derived the system of equations that must be satisfied and showed that the results derived using actual numerical examples are valid.
