What two factors determine the risk of damage from noise exposure?

The correct answer, which focuses on loudness and duration, underscores two critical elements that significantly influence the risk of noise-induced hearing damage. Loudness, often measured in decibels (dB), reflects the intensity of the sound. Higher decibel levels indicate louder sounds, which can potentially cause more harm to the auditory system. Duration refers to the length of time an individual is exposed to a particular noise level. Increased exposure time to loud sounds further elevates the risk of damage, as consistent or prolonged noise can lead to cumulative effects on hearing.

Understanding the interplay between loudness and duration is essential in audiology. For instance, brief exposure to an extremely loud noise (like a gunshot) can cause immediate hearing loss, while prolonged exposure to moderately loud noise (such as music at high volume) can lead to gradual hearing deterioration over time. Thus, both factors are pivotal in assessing individual risk and the necessary preventive measures needed to protect hearing health.
