When a sound wave hits a wall, the amplitude of the wave decreases due to reflection. Some of the sound energy is absorbed by the wall, some is transmitted through it, and some is reflected back into the original space. This results in a decrease in the overall energy and amplitude of the sound wave.

What happens to a sound wave when it is reflected off a wall as an echo?
When a sound wave is reflected off a wall as an echo, it bounces back and reaches our ears after a short delay, creating a repeated and fainter version of the original sound.
What happens to sound waves when they reach a wall or other solid flat object?
When sound waves reach a wall or solid flat object, they are partially absorbed by the material and partially reflected back. The reflected sound waves can interact with incoming sound waves, causing constructive or destructive interference. This can result in changes to the overall sound quality and volume in the surrounding environment.
How does sound bounce off walls?
Sound bounces off walls due to the reflection of sound waves. When sound waves hit a wall, they bounce back in the opposite direction, creating an echo or reverberation effect. This happens because the wall's surface is hard and smooth, causing the sound waves to reflect off of it rather than being absorbed.
How can sound be amplified through a wall?
Sound can be amplified through a wall by using a device called a speaker or a sound amplifier. The sound waves travel through the wall and are then amplified by the speaker, making them louder on the other side of the wall.
How can you make the volume of a vibrating louder?
To make the volume of a vibrating object louder, you can increase the amplitude or size of the vibration. This will result in a greater displacement of the air particles, producing a louder sound. Additionally, you can position the vibrating object closer to a resonant surface, such as a wall or table, to amplify the sound.
What happens when a sound wave hits a wall?
when a sound wave hits a wall it refracts and loses velocity but carrys on. if there is another wall within its distace then it will refract gain. this can cause an echo
What does a sound wave do as its energy is used up?
The eventual diminution of a sound waves is usually as heat dissipation in the wall materials, or perhaps in specially designed sound absorbers. During this process, the original amplitude of the wave will gradually diminish.

How is echo produce?
Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water.
What happens to an ultrasound ray when it hits a boundary?
First off, Ultrasound is not a ray. Like all sound, its a wave. Ultrasound simply means its so low in pitch, its below the human hearing range.When a sound wave hits a barrier, two things happen. The energy from the wave is partially absorbed into the barrier itself, which will now vibrate with that energy. Also, some of the energy from the wave is deflected, or bounced off.Think of it as being how you can hear someone talk through a wall. Even though the sound waves are bouncing off the wall, and therefore a small room like a closet would amplify the sound, its still being transferred through the wall.
Susie hammers on a block of wood when she is 85 m from a large brick wall Each time she hits the block she hears an echo 0.5 s later With this info calculate the speed of sound?
To calculate the speed of sound, we can use the formula speed = distance/time. Since the sound travels from Susie to the wall and back, the total distance is 2 * 85m = 170m. The total time for the sound to travel this distance is 0.5s (from Susie to the wall) + 0.5s (from the wall back to Susie) = 1s. Therefore, the speed of sound is 170m / 1s = 170 m/s.
