Olfactory threshold

The olfactory threshold is the smallest amount of a smell that a person can detect, essentially the faintest odor detectable by the sense of smell. It varies among individuals and can be influenced by factors like age, health, and environment. This threshold helps scientists understand how sensitive a person’s sense of smell is and is important in fields like perfume development, food testing, and diagnosing certain medical conditions. In simple terms, it’s the point at which an odor becomes noticeable to your nose.
