Which of the following practices helps in managing noise exposure?

The practice of using barriers and protective equipment is an effective way to manage noise exposure in various environments, especially in workplaces where loud sounds are prevalent. This method focuses on minimizing the impact of noise on workers' health by creating physical barriers that absorb or deflect sound waves and by providing personal protective equipment, such as earplugs or earmuffs, that reduces the level of sound that reaches an individual.

Implementing barriers can involve installing sound-absorbing panels or enclosures around noisy machinery, while protective equipment directly protects employees’ hearing. This approach is vital as prolonged exposure to high noise levels can lead to permanent hearing loss and other adverse health effects. Utilizing such measures contributes to a safer work environment and fosters compliance with occupational health and safety regulations regarding noise exposure limits.

Other strategies, such as allowing breaks for employees, can provide temporary relief from noise but do not address the underlying exposure issue in the same direct manner as barriers and protective equipment. Increasing the number of shifts could potentially increase the overall noise level in the workplace, and encouraging loud communication is counterproductive to managing noise levels effectively.
