SPHSC 582: WINTER 2006 Lab 2 Hearing Aid Programming I To gain access to hearing aid programming, 5 main hardware/software components are necessary: 1) Hearing aid A hearing aid that can be programmed is either digitally programmable or digital. This means that controls such as maximum output, gain, frequency response, etc. are adjusted through the use of a computer. 2) Cables The cables connect the hearing aid to the HiPro box. It is important to know how the cable connects to the hearing aid. If you twist when you should push or push when you should twist, you could ruin the cable or, even worse, ruin the hearing aid. Pay particular attention to the number of prongs, location of prongs, directions of twisting, etc. 3) HiPro The HiPro box is an interface that connects the hearing aid to the computer (specifically to NOAH and the manufacturer modules). It is important to connect the right aid to the right port and the left aid to the left port of the HiPro box. 4) NOAH NOAH is a database-type software program consisting of 3 main modules: 1) Patient Module, 2) Audiometry Module, and 3) Manufacturer Module. The patient and audiometry modules allow you to enter and save patient and audiometry information. The manufacturer module is used in programming the hearing aid. NOTE: Website for technical information and training on NOAH: http://www.himsa.com/ 5) Manufacturer Module Hearing aid adjustment and programming occurs through the manufacturer’s module. Each manufacturer is different in the way they arrange their software/module, so it is important to become familiar with various manufacturer modules. In last week’s lab we covered the basic concepts of the first component (i.e. the hearing aid). Today we will work with the rest of the components. Regarding the manufacturer modules, we will focus on programming Phonak hearing aids during this lab, beginning with a simple Phonak hearing aid (Piconet2 P2 AZ) and ending with a more complex Phonak hearing aid (Valeo). Lab Assignment PART 1 (In NOAH) -Using the client module, come up with hypothetical patient information (name, date of birth). Make a note of your patient’s name because this will be the patient you will use to program aids in the future, and it will be deleted at the end of the quarter. -Using the audiogram module, enter your patient’s audiogram (Note: right mouse click allows you to delete thresholds or enter no response).
PART 2 (In the Phonak Manufacturer Module - PFG 8.5) PROGRAMMING PHONAK PICONET2 P2 AZ Click the Audiogram tab -Make sure the audiogram you entered in NOAH has been copied to the manufacturer’s audiogram section. Click the Instruments tab -Select Piconet2 P2 AZ hearing aid 1. Is this a digitally programmable or digital hearing aid? 2. Looking at the gain and MPO of this hearing aid, would it be considered a power aid? Click the Fine Tuning tab 3. Locate the overall gain, what is the range of adjustment? 4. Locate where the frequency response can be shaped; how many bands can be adjusted? 5. Approximate the frequency range that can be adjusted by each band. 6. Locate the MPO; what is the range of adjustment? Click the Programs tab 7. How many memories can be set for the user? -Set Program 2 to T-Coil 8. Is the T-Coil adjustment independent of the basic programmed gain or does it depend on where the gain has been set? PART 3 (In the Phonak Manufacturer Module - PFG 8.5) PROGRAMMING PHONAK VALEO 211 AZ Click the Instruments tab -Select Valeo 211 AZ hearing aid Click the Fitting tab; go to Manual Fine Tuning 9. How many programs are available for the user? 10. What is the frequency range for the overall gain, bass gain and treble gain? -Note that in addition to overall gain, the gain for this aid can be set differently depending on input/level (e.g. G50 and G80). 11. Under the G50 and G80 tabs, how many gain sliders can be adjusted?
