Sound energy passes through a hole by creating vibrations in the air molecules near the hole. These vibrations travel through the hole and continue to propagate as sound waves.
The size and shape of the hole, as well as the material it is made of, can affect how sound energy passes through. Additionally, the frequency and intensity of the sound can also impact its passage through a hole.
Yes, the size and shape of the hole can determine whether or not sound energy can pass through it. A smaller hole or a hole with irregular shapes can block or reduce the amount of sound passing through it.
The farther away from the hole, the more spread out the sound waves become. This can result in a decrease in the intensity of the sound, but it can still be heard depending on the size of the hole and the strength of the sound source.
When sound energy passes through a hole and encounters different materials, it can be reflected, absorbed, or transmitted. The type of material and its properties, such as density and thickness, can determine how much sound energy is reflected, absorbed, or transmitted through the hole.
