An ear-level hearing device and a handheld computer with a graphical user interface determines a subject's own hearing threshold. Hardware includes the smartphone, viewing screen of the smartphone, smartphone software, ear level hearing device, transmitter on the smartphone and receiver on the ear level device (ELD) communicating with the graphical user interface on the smartphone to the ear level hearing device. The interface on the smartphone may include an automatic routine or buttons to vary frequency and amplitude of a frequency dependent sound presentation to the earpiece. Software installed on the hand-held smartphone system sends wireless signals to the ELD changing acoustic parameters in the listening device. The ELD stores frequency/amplitude parameters of the thresholds and wirelessly delivers them to the smartphone. The smartphone uses the threshold data to derive the appropriate amplified acoustical signal (relative to the thresholds) to the subject.
