I have worn custom ear molds ever since I started wearing hearing aids primarily because of the cause of my hearing loss. I have had the same pair for at least 10 years. My question is who or how is the configuration or specification for custom ear molds determine? I ordered new molds when I got new this year. They came in looking significantly different than prior molds - vent holes were missing or significantly smaller than in prior molds. Who or what determines the location/size of vent holes? Does anyone have any clue on this?
