The unit used to measure the intensity of sound is the decibel (dB).
Explanation:
- The intensity of sound refers to the amount of energy carried by sound waves per unit area.
- The decibel is a logarithmic unit that measures the ratio of the intensity of a sound wave to a reference level.
- The reference level is usually set to the threshold of human hearing, which is considered to be 0 decibels (dB).
- Sound intensity increases exponentially as the decibel level increases.
- The decibel scale is used because the range of human hearing is vast, from the faintest sound that can be detected to extremely loud sounds that can cause damage.
- Some common examples of sound levels in decibels include:
- Normal conversation: about 60-70 dB
- Vacuum cleaner: about 70-80 dB
- Rock concert: about 110-120 dB
- Jet engine: about 140-150 dB
- The decibel scale allows for a more practical representation of sound levels and their effects on human hearing.
- It is important to note that the decibel scale is logarithmic, meaning that a 10 dB increase represents a tenfold increase in sound intensity.
