An advanced 3D audio communication systems is
developed by a team led by Sennheiser Canada under the Canadian
Soldier Integrated Headgear System (SIHS) program. The team also
includes AuSIM Inc. from the US and Britain's Davies Communications
from the Selenia Communications group.
The soldier-worn systems will provide
three-dimensional reception of electronic communications and 3D
audio cues to enhance situational awareness. 3D audio feature
provides spatial information of the incoming call, improving the
soldier's capability to monitor multiple communications channels and
prioritize important information as it is received. 3D cues are
based on GPS information encoded with every transmission. SIHP
monitors the soldier's head position, decodes the incoming signal,
and plays the signal in 3D audio, accurately simulating the source
of the signal's location. The system also function as a navigation
guide, triggering audible cues near navigation waypoint, alerting of
threat locations and exposure to enemy line of sight etc.
The SIHS performs as "transparent" system,
maintaining the wearer's natural hearing throughout the use of the
system. It also protects the user's hearing from the damage of loud
or impulsive noise, using active noise reduction.
