Iodine deficiency related to hearing loss

Have been doing some homework relating to vitamin D deficiencies and am finding all sorts of good things, including the fact that deficiencies can lead to hearing loss.  In that search I've also found that insufficient iodine is also a contributor to hearing loss.  Have had some form of hearing loss all my life and don't see anything that says I can restore it, but will keep on looking.  Am taking large amounts of vitamin D3 and have continued my iodine intake, but now at a reduced rate.

Here's a tidbit I found regarding iodine and hearing loss - the type of hearing loss they describe is nerve related, and that's where my loss is at.

Iodine
Although iodine deficiency is most commonly associated with endemic goiter (overgrowth of the thyroid gland caused by lack of iodine in the diet), studies in animals and humans find that iodine deficiency also has a role in sensorineural hearing loss (Meyerhoff 1979; Wang et al. 1985; Delange et al. 1989; Valeix et al. 1992, 1994; DeLong 1993), including middle ear changes, cochlear lesions, congenital deaf-mutism and bilateral hearing deficits, and high hearing thresholds in children. Adequate maternal iodine status is critical for brain development of the fetus, beginning about the 14th week and continuing perhaps into the third trimester (DeLong 1993). Iodine is available from household salt. However, levels of iodine content are deliberately low in some types of table salt in an effort to compensate for the excessive use of table salt by many persons (Delange et al. 1989). Certain medical conditions also require strict limitation of dietary salt, further reducing intake of iodine.
