Hearing loss can be classified into four types: conductive, sensorineural, mixed, or central. Sensorineural loss, or nerve deafness, is the most common hearing impairment (Better Hearing Institute, 1999). Hearing impairment can also be defined by severity of loss. A decibel (dB) is the unit used to measure the loudness of sound. The higher the dB, the louder the sound. Mild loss refers to sounds less than 40 dB; these individuals are often referred to as hard of hearing and have difficulty with quiet or distant speech. Moderate loss involves sounds between 41 and 70 dB; individuals with this degree of loss typically require a hearing aid but can hear when facing the speaker within 3-5 feet. Severe loss includes sounds between 71 and 90 dB; persons suffering this degree of loss require a hearing aid but may hear loud noises one foot from their ear. Profound loss refers to the sounds over 90 dB; a hearing aid and specialized training are necessary for individuals with this degree of loss. The term deaf refers to individuals with a loss above 70 dB."}
