What maximum noise levels?

Maximum noise levels refer to the highest permissible sound intensity measured in decibels (dB) that is considered safe for human exposure in various environments, such as workplaces or public areas. For example, the Occupational Safety and Health Administration (OSHA) sets a permissible exposure limit of 90 dB for an 8-hour workday. Prolonged exposure to noise levels above 85 dB can lead to hearing damage. Regulations may vary by country and specific context, so it's essential to consult local guidelines for precise limits.
