Which of the following is a disadvantage of using pneumatic systems?

The noise produced during operation is indeed a recognized disadvantage of using pneumatic systems. Pneumatic systems rely on compressed air to generate movement, and the rapid release of air can create significant sound levels. This noise can not only be a source of discomfort for operators but may also lead to stricter noise regulations in certain environments. Continuous exposure to loud environments can pose health risks, including hearing loss, which necessitates additional measures like soundproofing or personal protective equipment.

In contrast, while factors like cost, load handling capabilities, and parts availability may present considerations when evaluating pneumatic systems, they are not universally recognized as disadvantages in the same manner as operational noise. Many industrial environments utilize pneumatic systems effectively despite these challenges, focusing on the benefits such as flexibility, ease of control, and the ability to generate rapid movements. However, the operational noise can significantly impact user experience and workplace conditions, making it a notable disadvantage.
