How long does impulse or impact noise, such as gunfire, typically last?

Impulse or impact noise, such as gunfire, is characterized by a very short duration, typically lasting less than one second. This type of noise is defined by sharp, brief sounds that occur suddenly and reach high decibel levels, which can potentially cause immediate hearing damage. The quick nature of these sounds is crucial to understanding their impact on hearing health, as the brief but intense sound waves can lead to acoustic trauma.

In contrast, other response options suggest longer durations, which do not accurately reflect the characteristics of impulse noise. Understanding the short duration of such noises and their potential effects on hearing helps audiology health technicians assess risks and educate individuals about safety and prevention measures regarding exposure to loud sounds.
