The characteristic of sound that is characterized by terms like soft, medium, or loud is **intensity**.
1. **Intensity** refers to the amplitude or volume of sound waves.
2. Soft sounds have low intensity, medium sounds have moderate intensity, and loud sounds have high intensity.
3. Intensity is measured in decibels (dB).
4. For example, a whisper would have low intensity (soft), normal conversation would have moderate intensity (medium), and a shout would have high intensity (loud).
In summary, intensity describes the strength or power of a sound wave, determining whether it is perceived as soft, medium, or loud.
