It is difficult to modify and tubing is secured using a CFA tube and seating ring. It can be appropriate for some patients with severe hearing loss using soft materials. Sound leaking out of the ear will be picked up by the mic, causing acoustic feedback. Open vents for low frequencies, feedback may occur if high-freq are too much. Fairly easy to modify at the clinic. Free shipping for many products! Hard acrylic (Lucite); 2) Hard light curing (UV) resin; 3) Soft acrylic; 4) It is used mostly with severe and profound hearing losses. The hard concha material would resolve our retention problem, whereas the soft canal portion will address the seal. Instead of a canal-lok, we use a skeleton style. Over the past several years, manufacturers have offered closed and double domes designed to close off the ear canal, increase low frequency gain, and thus extend the fitting range of these products.

Heat cure silicone is a better choice than platinum cure when high precision is needed for intricate details. I bought a special floss (NANOCLEAN) made especially for cleaning thin tube in hearing aids and my HA provider suggested it is causing the cracking. This is when the opening of the vent is narrower at the eardrum. In this respect, quasi-2D tin perovskites exhibit relatively slow crystallization and crystal growth rate compared to the three-dimensional analogues.
