Effect of white sound on pain threshold

Abstract

It has been claimed that intense acoustic stimulation, using "white sound", can reduce or eliminate pain. The effect of white sound on visceral pain produced by contraction of ischaemic muscle has therefore been investigated. Pain threshold estimations were made under the following conditions: (A) control; (B) music alone at comfortable listening level; (C) white sound of moderate intensity (90 db SPL); (D) white sound of maximum intensity (120 db SPL). The results do not indicate that sound stimulation alters the threshold for pain produced by the contraction of ischaemic muscle. © 1964 John Sherratt and Son.
