Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance)
Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)

Here are entered works on synthetic replicas of the ear used to restore cosmetic harmony to the face. Works on devices to improve hearing ability are entered under Hearing aids
Personal devices for protection of the ears from loud or high intensity noise, water, or cold. These include earmuffs and earplugs
