The description of different types of click molds on Siemens website is not too useful (https://www.bestsoundtechnology.com/pro/siemens-hearing-product-portfolio/product-archive/minireceiver/click-molds/). I went to my local audi to order click molds and what I got was a a long type of molds with 2 mm and 1 mm vents. I can hear almost normally below 500 Hz and above 4kHz having -60 dB at 2 kHz for both ears. So I know that I really need the short type of mold with larger vents for my hearing (to both reduce occlusion and let higher pitched sounds through as naturally as possible).
I told my audi that I’m not happy with the molds and that I need new ones. She talked to the local Siemens rep, who responded that they could try to cut the molds shorter and drill larger vents. So I guess that making new molds costs money and they are not too happy about the idea. Besides, I need a canal lock which I didn’t get (I’ve always needed one) that probably can’t be glued to existing molds by any reasonable means.
So, since I need new molds, I was thinking about my options besides short “closed” molds with large vents. I noticed that there are open molds as well and left wondering how they differ from “closed” molds and what type of hearing are they most useful for. I can’t reach local Siemens rep, so I thought to ask here.
I’m in the impression that the “open” molds are hollow with only a relatively thin shell. Is this correct? What confuses me is that I know that in Connexx software after choosing the coupling type to be either short or long click mold, you can only select closed, vent size or open. So open ones can’t have any vents in them? Some other manufacturers have hollow molds with a vent.
Can anyone explain what these open molds are and for what type of hearing are they the most suitable for? My audi doesn’t seem to know much about Siemens molds, so I probably need to give her the specs myself to get as good molds as possible.
