 It is now thought by professionals that Farr was possibly suffering from hyperacusis, which occurs when the olivocochlear bundle in the inner ear is damaged, causing it to lose its ability to soften and filter sound, making loud noises physically unbearable (auditory efferent dysfunction).Despite this, Farr was discharged from hospital and sent back to the front with the 1st Battalion of the West Yorkshire Regiment, a part of the 6th Infantry Division, with which he fought in the Battle of the Somme.Farr reported himself to the medical station several times over the following months.
