People with hearing impairment can do almost any job they choose. Offhand I can think of typist, clerk, data entry, mail room, warehouse, assembly, computer technician, guest room attendant (porter/maid/janitor), research assistant in a lab, certified nursing assistant/LPN/RN, x ray tech, medical assistant, social worker, bus driver, writer, graphic artist, mechanic, plumber, scientist, sonographer, webmaster... I could go on and on, I do this for a living pretty much 🙂
