Abstract

The three types of background noise on conversational speech intensity in individuals with hyperphonia and Parkinson's Diseases (PD), are discussed. Researces on PD subjects show that a Lombard relationship exists along with the control subject that may be related to a number of factors such as the severity of hypophonia, the type of background noise, the noise levels, the speech tasks, and the method of stimulus presentation. The subjects with PD are stabilized on their anti-Parisian medication and are tested at about one hour after their regular medication. Two separate two-factors repeated measures ANOVAs are used to examine the effects of each noise type on speech intensity. For each noise type, the group x noise level interaction is insignificant that reveals very few significant differences. The positive relationship between speech intensity and background noise is approximately parallel to that of controls.
