Laws will vary by jurisdiction and there may be exceptions or less restrictions for engines manufactured prior the passage of the latest statute. 75-80 dBA at 50 feet would be considered quiet in most states.
The legal decibel levels vary depending on the specific location and context, such as residential areas, commercial areas, or industrial zones. Generally, noise ordinances set limits on the decibel levels during the day and night to prevent disturbances and protect public health. It is important to check the local regulations to ensure compliance with the applicable laws.
The maximum range of detection for submarines using sonar varies depending on the decibel level. Higher decibel levels can detect submarines at greater distances compared to lower decibel levels.

In a busy city environment, average decibel levels typically range from 70 to 85 decibels.

Hearing protection is typically required at decibel levels of 85 or higher to prevent hearing damage.

Decibel levels are typically measured using a sound level meter. The meter captures sound pressure levels in decibels (dB). The measurement is usually taken at a specific location and distance from the noise source to determine the intensity of the sound.
Hearing protection can effectively block out decibel levels up to around 30-35 decibels.
Sounds above 85 decibels can damage hearing, especially with prolonged exposure. The risk increases with higher decibel levels and longer exposure time. It is important to protect your ears in environments with loud noise.
