People do not understand how diverse hearing problems are. Two children can have the same hearing loss but it can affect them differently. Even a slight hearing loss can be a real problem for a child. People think a hearing loss never alters. It can vary from day to day or week to week for various reasons, such as the child having a cold causing a conductive loss on the top of a sensorineural loss.
People think a hearing aid gives people normal hearing.
An aid helps but is not a cure for deafness. It is good to let people listen through a hearing aid with the sound turned down. This gives them a more realistic idea of what it is like to listen through a hearing aid. People do not understand how acoustics affect a hearing aid wearer. Often the classroom was very noisy.
