Common Safety Orientation (CSO) Practice Test

The maximum impact or impulse noise peak that should not be exceeded according to safety regulations is 140 dB peak sound pressure level. This threshold is established to protect individuals from hearing damage and other physiological effects that can result from exposure to high levels of noise. The rationale behind this regulation includes the understanding of how sound levels affect human health, particularly focusing on the potential for immediate and long-term hearing impairment.

Levels above this threshold pose significant risks, as noise at and above 140 dB can lead to immediate auditory damage and potential trauma to the ear. Regulations are often based on research findings that outline acceptable exposure limits to ensure safe working conditions. Keeping sound levels within this limit is essential in industries where high noise levels are common, such as construction and manufacturing, to prevent not only auditory damage but also to promote overall worker safety and well-being.
