- I expect that they should, correct?
- per this audi (Bryce Altus https://m.youtube.com/watch?v=c1dQvUAnZTY) the KS10 should use the same Cerustop wax guard on the black sticks (which I believe would be REF 098-0282), correct?
- Was custom ear mould made correctly by Phonak?
The way the ear molds were made even if wax guards were installed they would be recessed within the ear mould and a bit of a nuisance to replace DIY monthly. As you can see (red arrow) the speaker outlet ends within the mould.
Photos I have seen of custom ear moulds show a wax guard sitting flush with the opening which makes it both accessible And the speaker is radiating sound into the ear canal whereas with mine the sound enters a tiny diameter air space bouncing off of silicone mould for a distance of about 3mm before exiting into air space of ear canal. (Perhaps this is Phonak design intention that it be recessed and that Target software compensates for this aspect of the acoustic environment.)
===== detailed info ==========
{1} Silicone Slim Tip custom molds were ordered by Costco from Phonak and when Costco installed them they did not put in wax guards which might be a mistake on their part. I have flakey ear wax and use a Jodi HA vacuum so believe that ear wax on the speaker is probably not an issue.
{3} As you can see green arrow of photo of my mould the back of receiver and start of ear wire is not flush with back of ear mould. Below and purple arrow is from audi on YouTube and clearly my mould and wax guard relationship are very different! The opening in my mould does not allow for the receiver to go any farther into the mould.
Given the severity of my hearing loss, perhaps recessing the receiver within the mould is correct, yet want to have more confidence in the hardware fitting. As a very HA knowledgeable friend recently pointed out she thought the ear wire was a bit too long and contributed to one HA slightly dislodging at times. THe wire length also in her opinion put the mics slightly farther to the back of my head and probably had some impact on the processor comparing differences in sound from the front and rear mics as they were not in the sweet spot on the ear. While my aided hearing is âOKâ there is huge room for improvement so I want to give both hardware and software best shot at optimizing my hearing.
Thanks for your thoughts/experience.
