Above what level is noise considered a hazard to your hearing?

  1. 75 decibels

  2. 80 decibels

  3. 85 decibels

  4. 90 decibels

The correct answer is: 85 decibels

Noise is considered a hazard to hearing at levels above 85 decibels. At this threshold, prolonged exposure can lead to permanent hearing loss and other auditory issues, making it crucial for individuals working in noisy environments, such as laboratories, to use hearing protection and take preventative measures to safeguard their auditory health. Levels of 75 decibels are typically not deemed hazardous. While 80 decibels can be concerning, especially with extended exposure, the recognized level that requires serious attention regarding hearing protection begins at 85 decibels. Understanding this threshold is essential for ensuring safety and compliance with occupational health guidelines.
