Sensorineural sonus complete occurs due to any severe infectious disease, or sometimes is idiopathic in nature (Unknown cause). In these cases, people are often unaware of their hearing impairment until later in life. Gradual sonus complete can affect people of all ages and ethnicities. The possible causes of acquired hearing impairment include untreated middle-ear infection such as otitis media, excessive exposure to loud noises (loud music, fireworks, etc.), or a perforation of the eardrum. If hearing aids will help you, there's nothing shameful about wearing them.
