Description
A short-term data log periodically records device status and system events into
a circular buffer. A total of 512 events can be logged in the buffer which,
assuming a log interval of 1 hour, covers a total time period of over 4 weeks. A
separate long-term data log keeps track of how much time has been spent in
each program memory.
The ARD feature is intended for detachable RIC-style hearing aids. It provides
a means of automatically detecting the type of attached receiver link. ARD
operates in real time and provides rapid detection of the connected receiver
link with no audible artifacts.
The Pre Suite framework supports field upgradeable firmware.
Consists of a random noise generator with adjustable frequency shaping and
randomized time modulation for tinnitus treatment.
The MMI feature supports a push-button style volume control (up/down
presses), an 8-program memory select function, and an automatic telecoil
activation feature. Operation of the MMI is fully configurable, and the IO pins
used for the MMI functions are selectable through the Sound Designer
Software Windows application. Twenty-one different system events are
signaled through an acoustic indicator feature that supports both tone-based
and pre-recorded alert signals.
All device parameters can be accessed over both the wired and wireless
interfaces via the Sound Designer SDK. Wireless fitting is supported for
Windows, via NoahLINK wireless, Android, and iOS. By providing a consistent
API across multiple platforms, the Software Development Kit simplifies the
development of fitting software.
The Ezairo 7160 SL firmware bundle also provides numerous features
designed to simplify hearing-aid design and manufacturing. These features
include battery management, live display data, tone generation, and
feedback-path measurement.
