If a scuba diver descends also quickly into the sea, the internal pressure on all eardrum remains at atmospheric pressure while the external pressure increases due to the increased water depth. At sufficient depths, the dissimilarity between the external and internal pressures can rupture an eardrum. Eardrums can rupture when the pressure dissimilarity is as little as 35 kPa. What is the depth at which this pressure dissimilarity could occur? The density of seawater is 1025 kg/m3.
