I'm aware of WorkSafe and I know several people that work there. The form you submitted applies to occupational hearing loss, the kind where you work in a loud workshop whose environment noise is in excess of a specific dB level, not the kind self-imposed by listening to music 8 hours a day.
You appear to be in Vancouver or thereabouts. Worksafe BC absolutely does cover hearing loss. Here's the claim form:
