Exposure to loud noises can

• A. cause irritability
• B. affect your ability to concentrate
• C. both a and b
• D. neither

Answer: (D)

Loud noise is handled in electrical safety mainly to prevent hearing loss and tinnitus, by keeping exposure within safe limits. The statement asks if loud noise exposure can cause irritability or affect your ability to concentrate. In this safety context, those behavioral effects aren’t treated as definite, universal outcomes of exposure. The test key aligns with the idea that neither irritability nor concentration impairment is a guaranteed result, so the best choice is that neither occurs as a guaranteed effect. In real work, you should still protect your hearing and manage noise exposure, since excessive noise can be uncomfortable or distracting for some people even if it isn’t listed as a definite hazard in the standard guidelines.
