what would cause hearing loss in a child
Hearing loss Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins.[2] A common condition that results in hearing loss is chronic ear infections.[2] Certain infections during pregnancy such as syphilis and rubella may also cause hearing loss.[2] Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear.[2] Testing for poor hearing is recommended for all newborns.[6] Hearing loss can be categorised as mild, moderate, moderate-severe, severe, or profound.[2] There are three main types of hearing loss, conductive hearing loss, sensorineural hearing loss, and mixed hearing loss.[3]
Hoarse voice A hoarse voice, also known as hoarseness or dysphonia, is when the voice involuntarily sounds breathy, raspy, or strained, or is softer in volume or lower in pitch.[1] It can be associated with a feeling of unease or scratchiness in the throat.[1] Hoarseness is often a symptom of problems in the vocal folds of the larynx.[1] It may be caused by laryngitis, which in turn may be caused by an upper respiratory infection, a cold, or allergies.[1] Cheering at sporting events, speaking loudly in noisy situations, talking for too long without resting one's voice, singing loudly, or speaking with a voice that's too high or too low can also cause temporary hoarseness.[1] A number of other causes for losing one's voice exist, and treatment is generally by resting the voice and treating the underlying cause.[1] If the cause is misuse or overuse of the voice drinking plenty of water may alleviate the problems.[1]
