Currently there are regulations and guidelines that governing bodies have adopted when dealing with the emission of noise that make reference to or imply the term of inaudibility when setting criteria to be met for mechanical p lant and music noise after restricted hours. However, to date no such criteria has been established that can predict the inaudibility of these sources when combined with ambient backgrounds. As a result, stakeholders are met with uncertainty and designers are left with an inadequate subjective term when attempting to meet location-sp ecific noise criteria. This paper involves an investigation into the possibilities of conducting a psychoacoustic experiment that will test for the inaudibility of mechanical p lant and music noise in the presence of ambient background noise typical of the home environment situated in urban and suburban locations. This paper attempts to provide the framework for future larger scale investigations and provides the relevant findings and a methodology to assist in reducing the subjective nature of the responses observed. Through these future investigations, objective definable criteria from which to establish the inaudibility of mechanical plant and music noise in the presence of ambient background noise may be established
