What is the threshold of pain in terms of decibels?

• A. 120 dB
• B. 140 dB
• C. 160 dB
• D. 180 dB

Answer: (B)

The threshold of pain is defined as the level at which sound begins to cause discomfort or pain to the average human ear. This is typically recognized to be around 120 to 140 decibels. While individual sensitivity may vary, the accepted reference point for the threshold of pain is approximately 140 dB. At this level, sounds are not only overwhelming but can potentially cause immediate harm to hearing structures. It's important to note that exposure to sound levels at or above this threshold should be avoided, as they can lead to permanent hearing loss or other auditory damage. Understanding this level is particularly crucial for electricians and professionals working in noisy environments, as they need to take appropriate measures to protect their hearing and avoid exposure to harmful sound levels.
