I would say that it probably isn't technically any stronger, but the deaf person might be more aware of the sense of smell because they use it to compensate in some ways for the lack of auditory stimulation. Just a case of using it more than perhaps a hearing person would.
This is why wanted to ask ADers,To try to find out if its true and it seems like it might be true and that I am not nuts.
I know Jillio and Vampy are right that the heightened sense of smell for lots of deafies is subjective. In my case, as I became progressively deafer, the accuracy of my sense of smell increased.
My boss is so impressed with my sensitive nose that he has me walk through our bee yard and hive sites just to sniff out the early stages of "foul brood," a condition where we have to burn the colony, hive boxes and all.
I believe it is true too. I could always smell something that others around me couldn't. My Deaf friend told me of an incident recently at the chicken plant, she had smelled gas in the plant, she asked her co-worker/helper about it. The co-worker/helper realised about it and alerted the managers. They found a leak on the gas line.
YES
normal for hearing have 5 senses: audio, visual, touch, taste and smell
Each are 20% function in brain. Once one is miss such as audio that never use much. It cause other 4 function increase 5% more which mean, all are 25% each.
More we see, touch, taste and smell. Sometime, I felt we, deaf, see more.
