Since all subjects were previous users of binaural amplification, a brief orientation to the use of the experimental hearing aids should be sufficient. Subjects were issued a remote control with a volume control and three program buttons. Program 1 was set with the default setting (directional or omnidirectional). In order to ensure subject safety, an omnidirectional program was included in program two across both conditions; however, subjects were instructed only to use program two in situations where it was necessary to hear sounds from all angles equally (e.g. crossing the street in traffic, etc.). Program three on the remote control was set to mute, so that subjects could use only the first two programs. Subjects were be given identical instructions for both settings (omnidirectional and directional) and the investigator who gave the instructions did not know which setting was currently in the subject's hearing aids. Subjects were told that the hearing aids are likely to work best in noise if they could position themselves so that the signal of interest is in front of them and the interfering noise behind. Subjects were instructed on cleaning, care, battery usage, and volume control adjustment. Subjects were asked to wear the experimental hearing aids as much as possible during waking hours, minimally 6 hours/day. Subjects were asked to log their daily hearing aid use on a log sheet that will be provided to verify that they met the 6 hour/day. Additionally, subjects recorded how much time each day was spent in each of the two programs.
