A75 dB
B
C85 dB
D
AI Explanation
The correct answer is C) 85 dB. According to U.S. regulations, machinery control room noise must not exceed 85 dB. This requirement is specified in the Occupational Safety and Health Administration (OSHA) noise exposure standards, which aim to minimize the exposure of personnel to excessive noise levels in the workplace. The 85 dB limit is designed to protect workers from the potential health effects of prolonged exposure to high-decibel noise, such as hearing loss and other auditory issues. The other answer choices (A and D) are incorrect as they do not match the regulatory requirement of 85 dB for machinery control room noise levels.
