Navigating Arc Raiders' Stella Montis is always a pain, so I'm sorry to tell you that the On Deaf Ears quest sees you running from one side of the map to the other. At least you don't need to get lucky in finding a random item, like the With a View quest.
Below, I'll show you where you need to look to complete On Deaf Ears in Arc Raiders, digging up old research for everyone's favourite medical robot, Lance. I recommend bringing a Raider Hatch key with you, as it'll take some time completing the quest objectives, and you'll finish next to a hatch, too.
