Final answer:
The claim that only adults are affected by hearing loss is false; children and adults alike can experience varying degrees of hearing loss. Hearing aids can assist with different types of hearing loss, both sensorineural and conductive.
Step-by-step explanation:
The statement that only adults are affected by hearing loss is false. Hearing loss can affect individuals of all ages, including infants, children, and adults. Hearing aids may be effective in treating various forms of hearing loss such as sensorineural hearing loss and conductive hearing loss. Sensorineural hearing loss can be caused by aging, infections, head trauma, and exposure to loud noises, among other factors. Conductive hearing loss occurs when there's a problem with conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). If a child has a hearing loss of 60 dB near 5000 Hz, this indicates a much greater loss at that frequency compared to normal hearing, and sounds at 5000 Hz would need to be significantly louder than those at 400 Hz to be perceived as the same volume by the affected child.
