Which are reasons for a decrease in the intensity of sound as distance increases?

Multiple select question.

The temperature of the sound wave decreases as the sound travels.


Some of the sound's energy is converted to other forms of energy.


Sound does not travel through the air very well.


The energy of the sound wave spreads out as the sound travels.

Answer 1

The correct options for reasons for a decrease in the intensity of sound as distance increases are:

- **Some of the sound's energy is converted to other forms of energy.**
- **The energy of the sound wave spreads out as the sound travels.**

The other options are not correct reasons for the decrease in intensity:

- The temperature of the sound wave does not necessarily decrease as it travels; rather, it is the medium's properties (like temperature, humidity, etc.) that affect sound transmission.

- While sound can be affected by the medium it travels through, it can still travel effectively through air, especially over short distances; this statement is too general to be a correct reason for the decrease in intensity.
