The term "noise-induced hearing loss" (NIHL) refers to sensorineural hearing loss brought on by either acute acoustic trauma or prolonged exposure to loud noises. Noise exposure has the potential to permanently change the hearing threshold due to irreparable damage to the inner ear. Many risk factors affect the incidence of NIHL including personal factors; such as genetic factors, age, sex, and lifestyle; and elements relating to the noise; such as the length of exposure, its volume, and frequency. This study aims to explore the updated evidence concerning the causes, risk factors, diagnosis, and management of Noise Induced Hearing Loss that were carried out worldwide. The following databases were searched: PubMed, Web of Science, Science Direct, EBSCO, and the Cochrane Library. Using Rayyan QCRI, study papers were screened by title and abstract before being subjected to a full-text evaluation. Eleven research studies with participants of different ages and sexes appropriate to NIHL were included in this review and the relation between different variables with NIHL was discussed. NIHL is a significant problem, especially among industry workers with a high risk of noise exposure. The primary risk factors for NIHL are noise exposure type, intensity, and duration. Smoking and alcohol consumption also significantly affect hearing performance.
