What is the EPA's recommended exposure limit for noise to prevent hearing damage?

The Environmental Protection Agency (EPA) recommends that exposure to noise levels be kept at or below 70 decibels (dB) to help prevent hearing damage. This recommendation is based on research that indicates prolonged exposure to sound levels above this threshold can lead to hearing loss over time. Exposure to sounds at 70 dB or above, particularly for extended periods, can increase the risk of developing noise-induced hearing loss.

The recommendation aims to protect individuals in various environments, including workplaces and areas where loud noises are common. Understanding the significance of the 70 dB threshold is crucial for hearing health, especially in occupational settings, as it helps guide proper hearing conservation practices and informs individuals about the level of noise that is considered safe for prolonged exposure.
