Lecture 3 Flashcards
What are the 5 steps in the HA fitting process?
- Assessment
- Selection
- Fitting and Verification
- Orientation
- Validation
What are 3 common assessment goals?
- Is the patient a candidate for amplification?
- Audiological profile
- Communication needs
- Motivation - What hearing aid parameters and technology level should be fitted?
- What are the patient’s post-fitting rehabilitation needs?
What should we ask ourselves after an audiological assessment? How?
- What have we completed up to this point? What have we considered in our testing?
- Pure tone (CHL, SNHL), speech scores, speech in noise, MCL UCL, tinnitus
What should we ask ourselves about patient communication needs and motivation? How?
- What have we done to gauge our patient’s needs and motivation?
- Interviewed patient, hearing handicap inventory, asked them about their own motivation (COSI)
What is the main goal of the selection process?
Audiologist must determine what model(s) /style(s) are appropriate for the patient.
What are the 5 components of the decision making process?
- Manufacturer (guided by clinic, clinician preference, features of the devices)
- Technology level (i.e entry level vs. advanced)
- Features and options (user controls, telecoil, microphone configurations, multi-programs, accessories)
- Electroacoustic parameters (gain and output of hearing aid to meet hearing loss needs with prescriptive targets)
- Other considerations may include financial means, warranties offered, cosmetic preferences
Who are the big 5 Manufacturers?
- GN Resound
- WS Audiology (Widex, Signia, Siemens)
- William Demant (Oticon, Bernafon, Sonic)
- Starkey
- Sonova (Phonak, Kirkland, Unitron)
Once a model is selected, we must determine if the coupling to the ear is ____ or ____
custom, non-custom
If the hearing aid itself or earpiece is deemed to be custom, an ____ of the ear is taken.
impression
What 6 HAs need impressions?
- IICs
- CICs
- ITCs
- ITEs
- RIC custom shells
- BTE earmolds
What 2 HAs do not need impressions?
- RICs
- RITAs with use of domes
What do custom made products allow for?
Custom made products allow for a better seal, gain, and sound quality
Mild-moderate HL typically just need a ____
dome
Often times ____ feel more comfortable (however…)
domes, there isn’t always a perfect seal which can cause whistling)
How to communicate with a HA manufacturer (selection and ordring)
- Multiple ways to “order” hearing aids and accessories
- Each manufacturer will provide clinician/business with an account (number)
- Manufacturers will have courier, fax, email, or online portals to communicate between themselves and the clinicians
- Customer service departments, lab technicians, and audiology support services can be of great help— and they are willing to assist!
- Turnaround time being ordering a receiving devices can be varied- very short for non-custom pieces, usually within 1-2 weeks for custom products
When the devices arrive in clinic, what do you do before the patient arrives?
- Ensure order is correct!
- Review invoice/specification sheets (quality control measures)- more on ANSI testing in later unit
-
Pre-set devices for a “first-fit”
- Connect to software through Noah, input acoustic parameters (domes, venting option, receiver wire lengths, etc.), set any features you wish to do in advance
- Collect any other items (cleaning tools, wax filters, etc. that will be helpful during the initial fitting appointment)
What software produces the NOAH software platform?
HIMSA: Hearing Instrument Manufacturers’ Software Association
What is the wireless interface?
- NoahLink, or proprietary programming devices
- Eg. iCubeII/SurfLink/nEARcom
What is the wired interface?
Hi-Pro, connect devices with programming cables
What happens after the patient comes in to get their HAs?
We can verify the quality of the devices, and the means to which they suit/adequately fit the patient from both a physical and acoustic standpoint.
Explain quality control measures
Does the hearing aid pass QC, and how does the device performance measure to the manufacturers specifications?
Explain the physical fit of the HA
Does the device/custom piece/dome earmold fit comfortably, and is it fitting well on/in the ear? Can the patient position the aid correctly?
Hearing aid performance based on what audiological need?
REAL EAR MEASURES (REMs)/PROBE MIC MEASURES (PMMs) or test box measures
What are sound-field aided speech measures?
- Fit hearing aids, put them back in the booth to see how they are fitting
- Not done anymore (not as good as REMs)
