What Happens to the Sound Output When Increasing the Amount of Air Pressure Blown through a Train Horn?

Overview

Objectives/Goals My project was to determine if how loud a train horn sounds is a direct function of the amount of air pressure applied. I believe that increasing psi(pounds per square inch) to a train horn increases the decibel sound output in a linear fashion up to a certain point. Methods/Materials My project was to determine if how loud a train horn sounds is a direct function of the amount of air pressure applied.
