Weak Point

She knew the point from where the voice was coming from but she couldn’t just knock down the place with the hammer. She was afraid that she might hurt whosoever was making those obnoxious noises. So she first needed to find a weak point in the wall. She placed her ears against the wall to listen to the noise so that she would know the exact point she had to strike with a hammer. Would she be able to take out that was stuck inside the wall safely?
