Data are collated from all major public databases and used to generate an evidence-based single classification for each variant, which is then curated by experts in hereditary hearing loss. Aim: Pathological images in medicine should be diagnosed in time, and the disease should be accurately and efficiently classified by computer vision.In this chapter, we are devoted to the classification of hearing loss images. Degree of hearing loss based on the PTA of 500, 1000 and 2000 Hz air conduction thresholds Hearing loss configuration is classified in accordance with the shape of the air con- duction audiogram. This number could rise to over 2.5 billion by 2030. The table below shows one commonly used classification system. When hearing loss occurs once language has been established. The degree of hearing loss can range from mild to profound: Mild Hearing Loss A person with a mild hearing loss may hear some speech sounds but soft sounds are hard to hear. Terms are based on the pure-tone average (PTA), the average of air conduction thresholds at 500, 1000, and 2000 Hz. In a developing child it can look like: misbehaving. Table 5: Correlation of old classification system with type of hearing loss. Certainly, normal pure-tone threshold sensitivity does not rule out hearing difficulty or the presence of auditory pathology, including cochlear and auditory neural peripheral or central deficits.
