H.B.
A person is deaf if they can not hear anything. A person is hearing impaired if they hear sounds but below a certain level. It depends on how much the child can actually hear to determine if she is deaf or hard of hearing. I have sensorineural hearing loss in both ears; I wear hearing aids. Without them, I can not hear the human voice unless someone is yelling in my ear. I am considered hard of hearing or hearing impaired rather than deaf, even though I can not function in society without a hearing aid.
The thing about conductive hearing loss is that it is usually repairable. Did your doctor tell you the cause? It could be a wax build up or a problem with the bones in the inner ear, both are usually repairable. A hearing aid can often help with this type of hearing loss as well if surgery is not an option.
