Factors affecting hearing in humans
The sample of the study involved 450 individuals from 13 countries. This also included people from different environment settings and cultures, especially rural communities and groups from other backgrounds who are often not well-represented in studies.
Hearing tests were conducted to examine the cochlear sensitivity in all these subjects. The tests measured Transient-Evoked Otoacoustic Emissions (TEOAE), soft sounds that the inner ear naturally produces when it hears a short sound, like a click or tone.
The results revealed some interesting insights. In addition to highlighting that women are better at hearing than men, the study also suggests that the environment in which a person lives plays a big role in their ability to sense sounds of different frequencies
