When a sound wave loses its sound, it means that the wave can no longer be detected by our ears or any other sound-detecting devices. However, the soundless wave itself still continues to propagate through the medium.
When a soundless wave encounters an object, what happens to the wave depends on various factors such as the nature of the object, the frequency of the wave, and the properties of the medium. In general, when a soundless wave encounters an object, it can undergo reflection, transmission, or absorption.
Reflection occurs when the soundless wave strikes a surface and bounces back, changing its direction. This is similar to what happens when light reflects off a mirror. The wave can bounce off the object and travel in a different direction.
Transmission occurs when the soundless wave passes through the object and continues its propagation on the other side. This happens when the object allows the passage of the wave without significant obstruction or reflection.
Absorption occurs when the soundless wave is absorbed by the object. The energy of the wave is converted into other forms, such as heat, and does not continue to propagate.
Whether the soundless wave can regain its sound or not depends on the properties of the object and the medium it encounters. If the object or the medium absorbs the sound energy, it may not be possible for the sound to be recovered. However, if the wave undergoes reflection or transmission and reaches a suitable medium or a sound-detecting device, it is possible for the sound to be recovered.
In summary, when a sound wave loses its sound, the soundless wave can still propagate through the medium. When it encounters an object, it can undergo reflection, transmission, or absorption. Whether the sound can be recovered depends on the properties of the object and the medium, and if the wave undergoes appropriate reflection or transmission to reach a sound-detecting device or a suitable medium.
