However, this can vary depending on:
* The individual: Some people naturally have louder or softer voices.
* The distance from the speaker: The farther away you are, the quieter the voice will sound.
* The environment: A noisy environment will make it harder to hear a normal speaking voice.
Here's a general comparison of decibel levels:
* 0 dB: The threshold of human hearing.
* 20 dB: A whisper.
* 40 dB: A quiet library.
* 60 dB: Normal conversation.
* 80 dB: Busy traffic.
* 100 dB: A lawnmower.
* 120 dB: A rock concert.
* 140 dB: A jet engine.
Keep in mind that prolonged exposure to sounds above 85 dB can damage your hearing.
