Background: Hearing loss in children if undetected can lead to delay in speech and language development, social and emotional problems, and academic difficulties. The importance of screening of school-age children to detect hearing loss cannot be overemphasized. In the Philippines, there is no single uniform program for hearing screening in school children. This study examines a device that has been proposed to be used for mass hearing screening. The device is called a hand-held hearing screener (Siemens Hear Check Navigator) that displays three colors as a result: green for pass or no hearing loss; yellow and red for fail or possible hearing loss. The objective of the study is to determine the accuracy of the hand-held hearing screener device as a hearing screening tool to be used in the school setting for first graders.
