* Distance between speakers: A conversation close up will be louder than one from across a room.
* Volume of speakers: Some people naturally speak louder than others.
* Environment: A noisy environment might require people to speak louder to be heard.
* Emotional intensity: Excited conversations tend to be louder.
Generally, however:
* A typical conversation at a comfortable distance is around 60-70 decibels (dB).
* A very quiet conversation might be around 40-50 dB.
* A loud conversation might reach 70-80 dB.
For reference:
* A whisper is around 30 dB.
* Normal background noise is around 40-50 dB.
* A lawnmower is around 90 dB.
* A rock concert can reach 120 dB or more.
It's important to note that prolonged exposure to sounds above 85 dB can damage your hearing. So, while a normal conversation is usually within a safe range, it's good to be mindful of your surroundings and avoid excessively loud environments.
