Is 20 dB very loud?

Could you please clarify for me, is 20 decibels (dB) considered to be a very loud noise level? I understand that decibels are a logarithmic scale used to measure sound intensity, but I'm unsure of how to interpret the specific number of 20 dB in terms of its perceived loudness. Is it comparable to the sound of a whisper, a normal conversation, or something louder? Thank you for your assistance in clarifying this matter.
