Why does something that is soft absorb more sound than something that is hard?
Soft materials have a porous structure that allows sound waves to penetrate and get trapped inside, reducing the sound's ability to bounce or reflect. In contrast, hard materials reflect sound waves, causing them to bounce off surfaces and remain in the environment. This difference in how sound waves interact with soft and hard materials contributes to the soft material's better sound absorption properties.
How does soft material absorb sound vibrations?
Soft materials absorb sound vibrations by converting the acoustic energy into mechanical energy within the material itself. As sound waves travel through the material, their energy is dissipated as they cause the material to vibrate internally, reducing the amplitude of the sound waves. This process is facilitated by the ability of soft materials to deform and dampen the sound waves effectively.
Why do soft things absorb sound?
Soft things absorb sound because their porous and fibrous structure allows them to trap sound waves, which then get converted into heat energy. The material's ability to dissipate and scatter the sound waves rather than reflect them helps reduce reverberation and echo in a space, leading to a quieter environment.
What control how loud or soft sound is?
The amplitude of a sound wave determines how loud or soft a sound is. Greater amplitude produces a louder sound, while smaller amplitude results in a softer sound. This is perceived by our ears as variations in volume.
The difference between pitch and volume?
Pitch refers to how high or low a sound is, determined by the frequency of the sound waves. Volume, on the other hand, refers to how loud or soft a sound is, determined by the amplitude of the sound waves.
What kind of waves make soft sound?
higher waves

Are hard or soft surfaces best at reflecting sound?
Hard surfaces are better at reflecting sound because they do not absorb the sound waves as much as soft surfaces do. Soft surfaces, like carpets or curtains, tend to absorb more sound, causing less reflection.

How echo is formed?
An echo is formed by sound waves bouncing back off of solid surfaces. The greatest effect happens in small empty rooms with few or no soft furnishings. Soft furnishings absorb sound waves and so would counteract the effect.
When particles spread?
Sound does not spread out in particles but in waves. Imagine dropping a pebble in a still lake...and that is how sound waves spread out. Sound waves can also reverberate through harder materials; however, soft materials absorb the vibrations.
What is a soft repitition of sound?
A soft repetition of sound is known as an echo. This occurs when sound waves bounce off a surface and return to the listener, creating the perception of a repeated sound. Echoes are commonly heard in large open spaces or mountainous environments.
Why is the outer ear soft and flat?
So sound waves can bounce off the ear into the inner part.
When you scream into a pillow what happens to the sound waves?
When you scream into a pillow, the sound waves produced by your voice are absorbed by the pillow's material, which dampens their intensity. The soft fibers and structure of the pillow disperse and trap the sound waves, reducing their reflection and transmission. As a result, the sound is muffled, and less sound energy escapes into the surrounding environment, making it quieter.
The difference between pitch and volume?
Pitch refers to how high or low a sound is, determined by the frequency of the sound waves. Volume, on the other hand, refers to how loud or soft a sound is, determined by the amplitude of the sound waves.
