Effect of Distance on Sound Volume

What happens to the volume of sound as one moves away from the source?

• The volume of sound fluctuates

• The volume of sound remains the same

• The volume of sound increases

• The volume of sound decreases

Explain how distance affects the volume of sound using an example.

• Distance has no impact on the volume of sound

• Sound volume remains constant regardless of the distance

• The volume of sound increases as the distance from the source increases

• For example, if you are standing close to a speaker at a concert, the sound is loud. But as you move further away from the speaker, the sound becomes quieter due to the increased distance.

If you are standing 10 meters away from a speaker and then move to 20 meters away, what will happen to the volume of the sound?

• The volume of the sound will decrease.

• The volume of the sound will increase.

• The volume of the sound will stay the same.

• The volume of the sound will become louder.

How does the volume of sound change as you move closer to the source?

• The volume of sound increases.

• The volume of sound decreases.

• The volume of sound remains the same.

• The volume of sound becomes silent.

Describe the relationship between distance and sound volume.

• As the distance from the sound source increases, the sound volume decreases.

• As the distance from the sound source increases, the sound volume increases.

• Sound volume remains constant regardless of the distance from the sound source.

• The relationship between distance and sound volume is not related.

What is the scientific term used to describe the decrease in sound volume as distance from the source increases?

• Attenuation

• Amplification

• Magnification

• Intensification

Why is it harder to hear someone talking from a distance compared to when they are close to you?

• The background noise at a distance interferes with hearing the person talking

• The air at a distance absorbs the sound waves, making it harder to hear

• The person's voice changes frequency at a distance, making it harder to hear

• The sound waves from a person talking at a distance are weaker by the time they reach your ears, making it harder to hear them compared to when they are close to you.

If you are in a large hall and the speaker is at the other end, how will the volume of the sound change as you walk towards the speaker?

• The volume of the sound will remain the same as you walk towards the speaker.

• The volume of the sound will decrease as you walk towards the speaker.

• The volume of the sound will fluctuate as you walk towards the speaker.

• The volume of the sound will increase as you walk towards the speaker.

What are some ways to increase the volume of sound when it reaches a distant listener?

• Whispering to the listener

• Using a smaller source of sound

• Increasing the background noise

• Using a louder source of sound, using a megaphone or speaker system, and reducing background noise to improve clarity.

Explain how the effect of distance on sound volume can be observed in everyday life.

• Sound volume remains constant regardless of the distance from the source.

• The volume of the sound increases as the distance from the source increases.

• There is no effect of distance on sound volume.

• The volume of the sound decreases as the distance from the source increases.
