The construction of sound intensity apparatus and experiments on the relative intensity of successive, simultaneous, ascending and descending tones

Abstract

"From the impression which gradually developed during the course of the experiment it seems probable to the writer that both difference in vibration rates and the ratios of the intervals have an influence upon the judgments of the tone intensities. It is these facts mainly which led him to conclude that the intensity judgment in audition is really a mixed judgment. A tone may be judged as strong as another tone one moment, but presented again a few moments later, they will be judged of different intensity."--Text taken from page 80.
