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 DREAM hearing aids maintain the inten-
sity level difference between ears (inter-aural 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 improve speech understanding for
some wearers.
More accurate identification of feedback – The DREAM hearing aids distin-
guish between “true” hearing aid whistling (or feedback) and music sounds
to prevent unnecessary feedback cancellation and preserve natural sound
quality.
