Thresholds for nine food odors were found for two groups of subjects, young and elderly. Dravniek's dynamic triangle olfactometer, which employs the forced-choice, triangle principle and controls for guessing was used. Elderly subjects were found to have a considerably reduced sensitivity to these odors compared with young subjects.
针对两组受试者，即年轻人和老年人，测定了九种食物气味的阈值。使用了德夫尼克动态三角嗅觉计，该仪器采用强制选择、三角原理并控制猜测因素。结果发现，与年轻受试者相比，老年受试者对这些气味的敏感度大幅降低。
