sensitivity smell

Do people have the same sensitivity to smell? Place people at one end of a room. Have another person open a scent, such as lemon oil or vinegar. Have your test subjects write down what they smell and what time they smelled it. Is the time the same for different scents? Does it matter whether the test subject was male or female?
