My audiologist gave me the following prescription for me to bring to the hearing aid specialist:
closed custom earpiece with pressure venting
During my initial meeting with the HAS a slimtip or a cshell was mentioned. Eventually a Phonak slim-tip was choosen by the HAS to go with my Phonak Audeo Marvel M50-R.
This is my slimtip:
Now my questions.
Q1: is this considered a Acoustically Optimized Venting (AOV) mold?
Q2: what do the numbers mean which are printed on the slim-tip? It shows:
114 981 M
(During programming of the HA my HAS explictly had to lookup a number (maybe 1 of these?) related to the earpiece and entered it in the Phonak Target software.)
Q3: Is there a way for the HAS to look/see (or other means) to verify if the fit of the earpiece is like it should?
Extra info on Q3:
this is my first earpiece so I have nothing to compare. This earpiece gives me a slight pressurepoint resulting in a minor pain sensation. If I slightly move the earpiece by pressing on the extension which anchors in my ear shell the discomfort is gone for a period but after a while the discomfort returns. It seems the earpiece can rotate a tiny amount. It is really a minor pain sensation, I am unsure if this will go away over time after getting accustomed? I wear this earpiece now for 7 days.
Furthermore I sometimes experience a little resonance in certain sounds which seem to go away if I touch the anchor extension of the earpiece. Please note I am not sure if I am describing this resonance correctly and if it is really affected by touching the earpiece anchor.
Q4: my HAS inserted the receiver (2M) into the slimtip using her fingers instead of using the Phonak specific tool. Is inserting the receiver something which can be done incorrectly resulting in suboptimal sound?
Q5: how come Phonak does not provide cleaning instructions on the venting channel while a clogged venting channel causes discomfort and probably also impacts sound? My HAS also did not mention I should clean the vent. At one moment I heard annoying popping sounds which I believe were caused by the clogged vent.
A lot of questions… hopefully somebody can share their knowledge/experience on 1 or more questions!
