Behavioural tests such as 条件游戏听力测量 (CPA) or 视觉强化听力测量 (VRA) require the child to be awake and respond to the sounds via
behavioural conditioning using toys and listening games. CPA is for children aged 3
to 5 years old and VRA is for younger
toddlers aged 2 to 4 years old.
耳声发射(OAE) is a test that determines the status of the inner ear/ cochlea (specifically hair cell function). It measures otoacoustic emissions or OAEs. These are sounds given off by the inner ear when responding to a sound. The OAE test is often part of a newborn hearing screening program and pediatric hearing assessments.
