higher waves
No, a soft sound typically has low amplitude waves (shorter in height) compared to a loud sound that has high amplitude waves (taller in height). The amplitude of a sound wave is directly related to its volume or intensity.
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.
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.
A soft "coo" 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.
There are a lot of different animals that have a soft sound from a bird like animal an owl to other rodent animals that don't make much noise at all like a chipmunk.
Soft surfaces absorb sound waves rather than reflecting them, which helps to decrease the overall volume of sound. This absorption reduces the reverberation or echoing effect that can amplify and sustain sounds in a space. Soft materials like carpets, curtains, and upholstered furniture are commonly used in buildings to help dampen sound and create a quieter environment.
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.
To make it crackle.
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.
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.
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.
