Patrick's hearing test

I took Patrick to the audiologist for a hearing test today. He did well (hearing threshold 30-40 db and above) and as expected failed the tympanogram, which is a test of the eardrum. There is fluid in his middle ear, so the eardrum is not working properly. Since the purpose of the eardrum is to amplify sound, when it is unable to move due to an obstruction, it leads to conductive hearing loss. Patrick's hearing loss is very minor, but it is causing some speech delays, so we will need to watch it closely.

On an interesting side note, I've learned that there is a group of people who intentionally rupture their eardrums in order to make diving and hunting at sea easier. Who knew?

Intentional rupture

The Bajau people of the Pacific intentionally rupture their eardrums at an early age in order to facilitate diving and hunting at sea. Many older Bajau are therefore hard of hearing.[2]
