The high performance of Dawson-type POMs in hole injection/collection ensures an efficient hole transfer from the organic layer to the anode, depressing the charge recombination in the optoelectronic devices. PE is also a hard material and is the most hypoallergenic material in the industry. Custom earmolds coupled to thin tube/wire devices have been shown to extend their fitting range to flat moderate to severe hearing losses. As expected, the green curve in Figure 7, which represents the larger vent diameter and shorter vent length, has significantly less low frequency gain compared to the earmold using a 1.5 mm parallel vent (purple curve).
