Which of the following can contribute to hearing loss?

Hearing loss can result from a variety of factors, all of which contribute to the overall risk and development of this condition. Exposure to loud noises is known to cause acute damage to hair cells in the cochlea, which are vital for hearing. Prolonged exposure can lead to permanent hearing impairment.

Ear infections can lead to conductive hearing loss, where the transmission of sound is impeded due to fluid buildup or inflammation in the middle ear. If recurrent or severe, these infections can have lasting effects on auditory function.

Old age, or presbycusis, is a common cause of sensorineural hearing loss, as natural degeneration of the auditory structures occurs over time. This age-related decline typically affects high-frequency hearing first.

Since all of these factors—noise exposure, ear infections, and aging—can independently and collectively contribute to hearing loss, it follows that the correct response encompasses the cumulative impact of all listed options. Understanding these various contributors highlights the importance of taking preventative measures and seeking medical advice when necessary to protect hearing health.
