‘There’s more to attraction than what meets the eye – Voice and scent play an underappreciated role in understanding attractiveness’, https://www.sciencedaily.com/releases/2017/05/170518083047.htm, ScienceDaily (May 18, 2017)
Whether by an off-putting body odor or a grating voice, it’s easy to understand how the nose and ears are just as important as the eyes in noticing how attractive someone is. It’s not particularly surprising that attractiveness spans more than just physical appearance, but most research has focused on looks, neglecting vocal and olfactory factors. (…) Perceiving others through all three channels gives a more reliable and broader variety of information about them. (…) Studies have shown that people can correctly deduce very similar types of information based on scent alone.
