My family feels I am loosing my hearing, but I hear fine, except when there is lots of noise. For instance if I'm in the kitchen cooking, have the vent on the stove on and someone speaks to me I can't hear what they are saying. Well I can hear the murmur, but can not make out what they are saying, unless it is completely quite or I'm looking at them. So, do you think I am loosing my hearing?
