An olfactory training using "Sniffin' Sticks" was performed on 91 patients aged between 50 to 84 years. The whole speculation lasted for five months. The result indicated that around 30% of the patient score a higher TDI-score after the training. The result is consistent with the experiment performed on patients of all ages. Therefore, the effect of aging on olfactory training can be neglected. Moreover, this experiment also recorded the score of auditory function. However, it did not show any significant difference between the performance before and after the training.
