This type of hearing loss is often due to genetic factors, a congenital defect or a malformation in the inner ear (cochlea). Sound waves are like water. The frequencies an ear can hear are limited to a specific range of frequencies. Hi! For the most part, the speech acoustics courses we took were viewed as theory.
