In this study, we used noninvasive physiological measurement of blood flow responses to provide evidence that infant crying sounds containing high-frequency components (HFCs) above the audible range significantly affect the breast blood flow of lactating mothers. None of the subjects recognized the HFC as sound when it was presented alone. Nevertheless, the values of oxy-hemoglobin concentration using NIRS (near-infrared stereoscopy) recorded from the both breasts significantly increased when the subjects were exposed to full-range sound compared with an otherwise identical sound from which the HFC was removed. Physiological evaluation indicates that the subjects felt the infant crying sounds containing an HFC below the level of consciousness. It might be important for normal biological communication between mother and child during the period when lactation is establishing.

在这项研究中，我们使用无创生理测量血流反应，以提供证据表明，婴儿哭泣的声音含有高频成分（HFC）以上的可听范围显着影响哺乳期母亲的乳房血流。当HFC单独出现时，没有一个受试者认为它是合理的。然而，当受试者暴露于全范围声音时，与去除HFC的其他相同声音相比，使用近红外立体镜（NIRS）记录的两个乳房的氧合血红蛋白浓度值显着增加。生理评估表明，受试者感觉到婴儿的哭声包含HFC低于意识水平。这可能是重要的正常生物之间的沟通，母亲和孩子在这段时期，当哺乳期正在建立。
