The sensory organ of hearing, the cochlea, emits faint sound as it processes incoming sound. Measurement of such "otoacoustic emission" in the ear canal provides evidence for how the live, healthy ear works. Emissions at mid frequencies associated with speech is usually of prime interest. Low-frequency hearing has not yet been characterized by measurement of low-frequency emissions from the cochlea. Low-frequency emissions are expected to be covered in sounds of breathing, blood circulation, and so on, if they exist at all at measurable levels. The present study shows, in essence, that the human ear emits distortion at least 1-2 octaves lower in frequency than has previously been shown. The emission is promising for further exploratory and clinical assessment of cochlear activity associated with low-frequency hearing.

Anders received his M.Sc. degree in acoustics in 2012 from Aalborg University. From 2012 to 2015 he was employed at Aalborg University, pursuing a PhD degree in the field of otoacoustic emissions. Anders was a visiting research student at the National Center for Audiology, Western University, in Canada, the Fraunhofer Institute for Integrated Systems in Germany, and the Auditory Research Laboratory, Northwestern University, Evanston, IL, USA.
