WebDec 30, 2015 · Abstract Background: According to the Fletcher-Peto curve, rate of decline in forced expiratory volume in 1-second (FEV1) accelerates as age increases. However, recent studies have not demonstrated that the rate of FEV1 decline accelerates with age among COPD patients.
The Fletcher–Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A.
