Subliminal threshold
The actual frequency of B could be determined in this way at any time, and its drift checked. It was adjusted to read correctly by the “zerobeat” method after the “settling down” period, and set to the particular frequency required B was brought into unison with it. A was therefore used as the frequency standard. 528 Hz Frequency (Love and Miracle Frequency) 432 Hz Frequency (Nature frequency) Alpha brainwave (To access the subconscious better) Power booster. fairly rapidly, and thereafter drifted quite steadily at the rate of 10-15 c./sec.

A, if allowed to run for about an hour, was very stable in frequency, varying by only 1 or 2 c./sec. Other Albums by Subliminal Threshold Affirmations. The first of these (oscillator A ) was already available, and has been described elsewhere (Shaxby and Gage 1932) the second (oscillator B) was a commercial oscillator of similar frequency range, viz. Two heterodyne oscillators were used to provide pure notes of the various frequencies used during the work. The experiments were also carried out with notes of different frequencies in the two ears in an endeavour to investigate the variations of total energy in such cases.
In this way it was possible to find the relation between the energy required at the monaural threshold and the total energy required at the “binaural” threshold determined under these conditions. The measurements were extended to the cases in which the subliminal note presented to the one ear w’as maintained at various levels below the monaural threshold, and the intensity of the note applied to the other ear to reach the “ binaural” threshold was determined. In the present work, this fact has been further verified.
In the course of the investigation of the possibility of forming a loudness scale, Churcher (1935), and Fletcher and Munson (1933), have found that the intensity of a note when heard binaurally may be assumed to be onehalf of that of the same note heard monaurally when the note is judged to be equally loud under the two conditions of listening. above the intensity in either ear at the binaural threshold.
Another form of the assumption is the statem ent that the monaural threshold intensity is 3.0 db. It has been assumed by some workers that the intensity of a note of any frequency in either ear at the binaural threshold is one-half of the threshold intensity in either ear when used alone, i.e.
