About

This study will evaluate the effectiveness of a speech-to-noise feedback procedure for the treatment of hypophonia in Parkinson's disease. The procedure includes a device that records the sound intensity level of the wearer's speech and compares it to the noise level around them. The device will provide the wearer with feedback if their speech becomes too quiet for them to be heard by their listener.
