A dog barking will not make a cake fall during cooking. There would need to be sound waves violent enough to break the bubbles forming in the cake for this to happen, and a dog barking is not that big a noise, and the cake is also insulated from noise by the door of the oven.
YES, while it is being cooked.
To start with the cake batter is liquid and as it warms up the raising agents in the batter release bubbles of carbon dioxide (the batter froths up) and this makes the cake rise. As the temperature gets even higher, the batter then begins to set with the mixture forming a framework round all the bubbles.
If, after the batter has frothed up, the still runny mixture (i.e. before it sets) is exposed to vibrations (sound is a vibration), these vibrations can cause the bubbles to move and coalesce so that the carbon dioxide escapes from the batter and the cake falls back and ends up as a hard lump when cooked.
No.
No; sound comes from vibrations.
By vibrations.

No, they make a higher-pitch sound - a squeak not a boom.
Making vibrations
No; sound comes from vibrations.
By vibrating, which induces vibration in the air, and sound is vibrations in the air.
By changing the electrical energy into sound energy and creating vibrations in the air.
Sounds are nothing more than tiny shaking movements of the air.Sounds are made when a material vibrates.Fast vibrations make a high sound, and slow vibrations make a low sound.Large vibrations make a loud sound, and small vibrations make a quieter sound.Plucking, blowing, shaking, beating or scraping can make sounds.Sound can travel through materials.Hard materials can reflect sound so that the sound travels back in the opposite direction. This is called an echo.Whales in the ocean "sing" to each other. The sound of their song can travel a distance of 800km.Sound moves through the air at 340m per second
An object makes sound by releasing sound waves that travel through the air, which we call vibrations
