Tympanometry is an objective measure of middleear function, and of how mobile the eardrum is.
A small rubber tip is placed into the earcanal, and a small amount of air is pumped into the ear to measure the mobility of the eardrum, the amount of pressure behind theear drum, and the volume of the middle ear space.
This test can detectwhether there is fluid behind the eardrum; a perforation of the eardrum; Eustachian tube dysfunction; a grommet insitu or blocked, causing or exacerbating hearing loss.

- Kendall Toy Test or KTT is a test which identifies a child’s ability to correctly point out a specific toy when its name is spoken at a minimal voice level, usually 40 dB(A). The child cannot lip read as the speaker will hide their face when talking, and the toys tend to be common toys that a two-year old could identify.
