Marian Scadden Cwerks Interactive Theatre   Thank you! Theater teachers--what a group--we're trying to get the kids to be louder while the poor classroom teachers are having to sush the children. I love using the Yacker Tracker because it's such a nice visual. The kids think I'm picking on them when I tell them to repeat/project/ louder. But when I bring out the Yacker Tracker, they can see for themselves--Yay!

Paul Pope, RN BSN ONC Assitant Director of Inpatient Orthopedic Nursing St. Johns Hospital Just wanted to let you know that I plan to use my Yacker Tracker in the nurses station at the hospital where I work. Noise levels, especially at change of shift, continue to be problematic. I am hopeful that the YT will help to raise awareness of noise (particularly voice noise) and its impact on patient comfort.
