When amplified optimally, children with hearing ability of 90dB or better should be able to identify environmental sounds and detect all the sounds of speech. Teachers and parents often investigate alternative methods of communication like sign language or cued speech to facilitate communication. Child may began choosing friends with like hearing impairments. Understanding speech when it is noisy becomes impossible. Child, with and without hearing aids, requires Assistive Listening Technology to combat normal classroom noise.
Child has to be taught every bit of information likely learned by normal hearing peers effortlessly.
In other words, child can not learn information by casually overhearing it. The child is aware of vibrations more than a tonal pattern. Speech is completely unintelligible. Child will respond on vision rather than hearing as a primary avenue for communication and learning. Detection of the speech signal is dependent upon loss configuration and use of amplification.
