Because they smell money, of course. And because they sniff a potentially big money-making opportunity, the pharmaceutical industry is racing to find treatments for a host of auditory disorders. It’s a shame there’s no money in prevention, because noise-induced hearing loss and most cases of tinnitus and hyperacusis are 100% preventable. So if you don’t have hearing loss, tinnitus, or hyperacusis yet, save yourself some cash and limit your exposure to noise now. Or try your luck and hope that at least one pharmaceutical company finds a cure before you experience symptoms.
