Is 50 dB too loud?

What is a good noise level for a home?
As long as the sound environment does not exceed 20 decibels, you are fine and sleep well, the noise is almost inaudible. Try not to exceed 40 decibels so that you do not hear any disturbing noise. Above 60 decibels, your quality of life and sleep decreases considerably and it is important to take action.
What is the ideal level of noise?
Decibel Level
Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
