Older **people** are more vulnerable to traffic accidents due to several factors. One of the main problems is that **excessive noise** in the environment can prevent them from hearing an approaching vehicle. This is especially important because many older people have **reduced hearing ability**, which makes it difficult for them to perceive important sounds on public roads.

In addition, older people may have **difficulties reacting quickly** to unforeseen situations, which increases the risk of accidents. Therefore, excessive noise not only affects their ability to hear but can also complicate their ability to **become aware of the presence of nearby vehicles**, thus increasing the risk of having an accident.
