Digital HI & PC Interface
Successful digital hearing instrument electroacoustic parameter settings require a connection system among the digital hearing instrument, the programming interface, and the computer.
Digital HI & PC Interface
The possibility to allow the dispensing professional to switch rapidly among various parameters, allows the wearer to judge which setting might provide better opportunities to hear speech in noise or in quiet surroundings.
Digital HI & PC Interface
The stored data in the hearing instrument will not be lost, even if the user must replace its battery.
Digital HI & PC Interface
The dispensing professional can access the data stored inside the hearing instrument by coupling the HI to a computer through an interface—most often HI-Pro.
Digital HI & PC Interface
Other interface options may be:
1. Noahlink ( a wireless/Bluetooth)
2. Manufacturer specific (cards, etc)
Digital HI & PC Interface
Once connected, the dispensing professional can adjust a variety of algorithms contained within the hearing instrument.
Digital HI & PC Interface
Each hearing instrument manufacturer has their proprietary software which may be accessed to make changes within the algorithms of their respective hearing instruments.
Digital HI & PC Interface
In 1993, the Hearing Instrument Manufacturer Software Association was formed (HIMSA).
Digital HI & PC Interface
Most of today’s manufacturers design their HI programming software to meet HIMSA standards.
In fact, much of today’s “diagnostic”
software is HIMSA certified to work well with computers.
Digital HI & PC Interface
Digital hearing instruments provide adjustment flexibility for a variety of electroacoustic settings.
These changes must be based upon the test information received during the patient’s audiometric examination.
Digital HI & PC Interface
Software structure for most manufacturer software include:
Patient/client profile information
Audiogram & real ear measurement data
Calculations of various fitting formulae
Fitting & fine tuning hearing instrument
Outcome and verification measurements
Digital HI & PC Interface
Several patient/client benefits have occurred as a result of the HI “digital paradigm”.
Less distortion and more clear sounds
Better sound pressure limiting systems
Multiple listening programs
More reliable/less repair
