If a diver ruptures an eardrum, which of the following symptoms might they experience?

When a diver ruptures an eardrum, the sensation typically involves sharp pain due to the sudden pressure change affecting the delicate structures within the ear. As the eardrum is a thin membrane that separates the outer ear from the middle ear, any rupture or perforation can lead to significant discomfort at the moment of the injury. Following the initial sharp pain, it is common for divers to experience some degree of relief, as the pressure that was causing the pain is equalized when the eardrum is compromised.

This symptom specifically aligns with the physiology of ear pressure regulation during diving, where the eardrum acts as a barrier. Other options, such as increased hearing ability, loss of consciousness, or reduced ability to speak, do not correlate with the consequences of a ruptured eardrum in the context of diving. Increased hearing would not be an outcome of a rupture, as damage tends to impair hearing rather than enhance it. Loss of consciousness is typically more indicative of severe decompression sickness or hypoxia, while speech ability is generally unrelated to a ruptured eardrum.
