Even with the hearing loss changes, prior to 2010, there was no threshold for entitlements to hearing aids. We put in a 6 percent hearing loss because that's what Australian jurisdictions did and it's what the United Kingdom did, and it actually recognised that between zero and 6 percent, there was little case to be had, according to the science, for a hearing aid to be provided. That was still the advice that officials gave us at 6 percent.
