Yes, if you hit your wall with a hammer, it will likely make noise. The specific sound produced will depend on various factors, including the material of the wall, the force applied, and the construction of the wall itself.
If your wall is made of a solid material like concrete or brick, it will produce a thudding sound when struck with a hammer. The impact of the hammer will cause vibrations that travel through the wall, resulting in a noticeable noise.
On the other hand, if your wall is made of a lighter or hollow material like drywall, the sound produced may be more of a dull thud or a loud knocking noise. The hollow space within the wall can amplify the sound and create a resonance effect.
It's important to note that intentionally hitting your wall with a hammer can cause damage to the wall, leaving behind visible marks or even creating holes. It's generally not recommended to strike your wall with a hammer unless you have a specific reason to do so, such as during construction or repair work.
