Loudness Function of a 1000-cps Tone in the Presence of a Masking Noise

Loudness levels of a partially masked 1060-cps tone are determined by loudness-balance procedures and, indirectly, by the methods of magnitude estimation and production. It is shown that loudness balances obtained by the method of adjustment are consistent with the loudness judgments obtained by the combined method of magnitude estimation and production, called method of numerical magnitude balance. The final results are in good agreement with those of other investigations in which balanced procedures were followed.
