Sound is mechanical energy. The energy displayed by the source is transferred into the medium through which it travels. When the wave, that moving energy, comes into contact with a surface, some of the energy is transferred into the surface. But how much? The more solid and "less moving" the surface (seen on a tiny scale), the less the moving air waves, those compression and rarifaction waves, can transfer energy into the surface. And that's what it's all about. The "softer" the surface, the more those pressure waves in air can affect that surface and transfer their energy into it.

∙ 15y agoUneven surfaces will refract the sound in many directions, but sound waves bounce evenly from smooth surfaces. Hence, smooth flat walls that cannot move away from the waves will reflect them back, a phenomenon known as "echo".

What happens when sound hits an object?
They are either absorbed [softsurface, e.g. wool] or refected [hard surface, e.g. metal]
Can sound travel around corner?
Sound certainly can travel around corners. Sound can also travel through hard surfaces like walls and bathroom surfaces as well.
Sound echo better off soft surfaces?
Since sound reflects off of soft surfaces better, it can reflect off of metal, walls, wood, paper, and a bunch of more soft surfaces.
What is meant by the reflection of sound?
Reflection is the return of sound waves from surfaces on which they are incident.
Why echo is not produced in many places?
Some surfaces reflect sound well, others don't.
What type of surfaces absorb sound?
a solid surface
What kinds of surfaces does sound reflect off best?
the more smooth the surface is the better the sound is
What does a cleaner ultrasonic do?
It cleans with vibrations of sound. You can clean floors and another variety of surfaces with it. It is used with a cleaning solution to clean surfaces.
What surfaces does sound travel through?
It travels best through solids
Could the tires on your vehicle make it sound different when traveling?
The tread on your tires has a particular sound. This sound will change on different road surfaces.
Do sound levels diminish more quickly outdoors or indoors?
Sound waves diminish according to the environment they are in. An anechoic indoor space (one that absorbs sound) will dissipate sound much faster than one with highly reflective surfaces (such as a room with stone surfaces). It doesn't matter if you're inside or outside, it just depends on the objects that surround the sound source.
What are the situations which echoes can be heard?
Echoes can be heard in environments with hard and flat surfaces that reflect sound waves, such as mountains, canyons, buildings, or empty rooms. When sound waves bounce off these surfaces and return to the listener, an echo is produced.
