Sound is a wave, the physical characteristics of sound are influenced by the properties of a wave. The basic properties of sound are pitch, loudness and tone. The loudness of the sound determined by the amplitude or height of sound waves. Amplitude is the displacement of a wave from its mean value. Greater the amplitude, the louder the sound. This means greater the amplitude, the sound will be louder. Amplitude is measured in decibels, thus loudness of sound is also measured in decibel.
Answer: Water that's safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn't necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.
