Corey, who himself has hearing loss, didn't know what to tell her. "We put the different masks onto the head-shaped loudspeaker and played the same sound for every test," Corey said. "Those sounds are already a challenge for those with hearing loss, with or without masks, and even become a challenge for those without hearing loss when you throw a mask into the mix." Almost everyone uses speech reading to some extent, with or without hearing loss, Corey said. The good news is that most masks do not completely block sound, they simply deflect it away from the mouth.
