It is hypothesized that various thoughts have varying intensities which cause involuntary muscle contractions or movements on a microscopic level in or near the ear, which generate pressure changes in or near the ear due to the compression of the air local to the ear. Nevertheless, regardless of the exact physical, chemical or neural mechanism, empirical testing has confirmed that thoughts generate small pressure changes in or near the ear of the …
