Synchronization of listening programs between hearing aids – The same lis-
tening program is used in both hearing aids when one is changed by the
user.
Surveillance of partner hearing aid – The hearing aid(s) will signal an alert
(“partner check”) when a hearing aid battery has expired, or that one of the
hearing aids has fallen off. In rare instances, a much stronger wireless source
nearby may activate this alert. This serves as an early warning to the wearer
of such service interruption. Coordination of compression – The UNIQUE
hearing aids maintain the intensity level difference between ears (inter-au-
ral level difference, ILD). In some situations where speech is presented to
one side and noise the other side, this coordinated action could enhance the
relative loudness of the speech sounds to the noise background and im-
prove speech understanding for some wearers.
More accurate identification of feedback – The UNIQUE hearing aids distin-
guish between “true” hearing aid whistling (or feedback) and music sounds
to prevent unnecessary feedback cancellation and preserve natural sound
quality.
