Which statement regarding noise is true?

The statement that adults are wakened by noise more easily than children is accurate because research has shown that children are generally deeper sleepers compared to adults. Children often have a higher threshold for disturbances during sleep, meaning that typical household and environmental noises might not rouse them as easily. In contrast, adults may be more sensitive to disruptions during sleep due to various factors, including stress levels, sleep patterns, and changes in health as they age, making them more likely to be awakened by noise.

In contrast, the other statements do not hold true based on studies of noise sensitivity. Healthy individuals tend to be less affected by noise compared to those with health issues, who may have heightened sensitivity due to stress or other factors. Middle-aged individuals may not necessarily be more sensitive to noise than the elderly, as sensitivity can vary widely among individuals based on various factors, including health and lifestyle. Additionally, studies on gender differences in response to noise have shown that there isn't a consistent pattern indicating that men are more easily disturbed by noise than women; reactions can be influenced by personal experiences and context rather than gender alone.
