Valsalva is the first to compartmentalize the ear into "internal, middle and external".

He also describes in this treatise what will be called the "Valsalva Maneuver" which consists in balancing the pressures on both sides of the eardrum. Maneuver well known to those who practice scuba diving or often travel by plane.
