What does life sound like for someone whose hearing has suddenly changed? Carly Sygrove is a British teacher living in Madrid. She was sitting in her school’s auditorium when suddenly her head was filled with a loud screeching sound. Diagnosed as sudden sensorineural hearing loss, Carly no longer has any functional hearing in her left ear, and battles with the whoops, squeals and ringing that comes from having tinnitus. Carly shares her personal story and speaks honestly about how life with hearing in only one ear is far from quiet.
