Abstract

The relationship between speech intensity and background noise in individuals with hypophonia and Parkinson's disease (PD) was analyzed. Ten idiopathic PD subjects with hypophonia and 10 age-equivalent controls were studied. A multi-talker noise was presented randomly to each subject in five dB increments ranging from 50-70 dB. It was found that subjects with PD show a systematic increase in speech intensity across increases in background noise.
