Sound waves can bounce backwards and forwards many times before they die out.
When sound waves reflect off walls, two things happen:
- They take longer to reach the listener.
- They lose energy (get quieter) with every bounce.

∙ 11y agoYes. Everything makes sound. Even small objects. For example, ants are really small. They make noise but you just can't hear it. The sound that bounces off a mirror can not be heard because it is too low. But sound can be bounced on a mirror.

∙ 8y agoLike any other wave sound is reflected when it encounters an impedance mismatch. The mismatch in impedance between air and the hard surface is quite large, so the wave reflects very efficiently.

∙ 8y agoIt depends on the nature of the material, surface texture and geometry of the material. Bread, as an example, is an open celled plastic that would deaden sound if you used it to paper your walls. A hard smooth plastic wall of plexiglass would reflect sound.Plastic surfaces and applications are available commercially that either reflect or absorb sound.

What are sound waves called?
Sound waves are called mechanical waves cause they need a material medium for their flow. Not only are they mechanical, but compression & lonqitudinal. -Apex:)
What are sound waves of irregular vibration in matter?
The sound waves of irregular vibration in matter is called noise.
How does sound waves travel through a material?
Sound waves travel through a material via VIBRATION. When sound waves hit an object at one end, the object's molecules at that end starts vibrating and during this vibratory motion they transfer their energy to neighboring atoms, hence cause a chain vibration and ultimately the waves reach at the other end.
What is meant by an echo and how it is caused?
sound can bounce of materials and/or go through them. When sound bounces, it's called an echo, from the mythological character echo, who could only say the words that someone else said to her. Echoes happen pretty much with every sound, but they usually aren't noticeable unless you go somewhere like a cave or yell really loudly.
Who studies sound?
An audiologist studies the properties of sound.
How does an echo work?
An echo happens when sound waves bounce off an object. That's why if you scream into a hollow cave, there is an echo. Because the sound waves bounce off the walls and back at you
What is it called when light waves do not bounce off an object?
Absorption; the light is absorbed by the object.
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine the speed of the object
What are echoes and how are they formed?
Sound that bounces back is called an echo and they are formed when sound waves are called a bellend.1. Sound travels in waves2. These waves bounce of nearly everything3. Sometimes these waves get absorbed or run out of energy4. If you are in a big room/place with nothing in these sound waves bounce around and end up coming back to your ears!
What happens to echolocation when it hits an object?
Echolocation is actually a process- it can't hit anything. In echolocation, high frequency sound waves are sent out by an animal. When these sound waves hit an object, they bounce off of it and reflect back to the animal. The animal can gather information about the object from these sound waves such as its size, shape, and distance.
Why Waves refracts?
not all of the waves are reflected.This is how it goes,if sound waves hit a smooth,hard surface.Some of the sounds are reflected.the sound that bounce back is called an echo
The use of sound waves by some bats to navigate and find food is called what?
Bats send out sound waves which bounce off of solid and liquid materials. They then locate the where the sound wave came from and can determine where the object is and what the object is. This form of navigation is called echolocation.
Does a reflection bounce off of a sound waves surface once the sound waves hit the surface?
no
How do sound waves travel what do sound waves need in order to travel?
sound waves bounce off of walls. they need air to travel.
Do objects block sound?
no, they absorb it or the sound waves bounce off.
What are reflected sound called?
Reflected sound is commonly called an echo. It occurs when sound waves bounce off a surface and return to the listener's ears after a short delay.
Do sound waves bounce off objects?
Yes
