Vanessa, I also received cisplatin as part of my treatment. Maybe the dosage wasn't that heavy, my hearing had not been affected. I did hear frequent buzzing sound like a train running by your side for about a month post treatment. I also heard occasional ringing sound and thought that someone was pressing the door bell. Luckily all these signs disappeared gradually and now my hearing is 100% back to normal. Yes, cisplatin is notorious for damaging our ears and the side effect can be chronic. You'd better discuss it with your doctor to see if anything can be done ASAP. Take care,

Karen stage 4 tonsil cancer diagnosed in 9/01.
