What is the decibel range of a normal voice conversation?

• A. 60-70 dBA
• B. 70-80 dBA
• C. 75-85 dBA
• D. 80-90 dBA

Answer: (B)

Normal voice conversation sits at a moderate sound level. At typical talking distance, casual speech is about 60 dB, sometimes a bit higher depending on distance and voice tone, and can approach the low 70s in closer proximity or when the speaker is slightly louder. The dBA weighting is used to reflect how our ears perceive different frequencies, so everyday speech is usually described in the roughly 60–70 dBA range. The higher ranges (70–80 dBA, 75–85 dBA, 80–90 dBA) correspond to louder scenarios like a raised voice in a noisy environment or louder machinery, not a normal conversation. So, the commonly expected range for a normal voice conversation is about 60–70 dBA.
