Children with hearing loss often cannot hear quiet speech sounds such as “s,” “sh,” “f,” “t,” and “k” and therefore do not include them in their speech. Thus, speech may be difficult to understand.
Children with hearing loss may not hear their own voices when they speak. They may speak too loudly or not loud enough. They may have a speaking pitch that is too high. They may sound like they are mumbling because of poor stress, poor inflection, or poor rate of speaking.
Children with hearing loss have difficulty with all areas of academic achievement, especially reading and mathematical concepts.
Children with mild to moderate hearing losses, on average, achieve one to four grade levels lower than their peers with normal hearing, unless appropriate management occurs.
The gap in academic achievement between children with normal hearing and those with hearing loss usually widens as they progress through school.
