How and why do we hear through the brick walls? Does the sound actually penetrate the walls?
Have you done any research? What have you found?mktsgm said:How and why do we hear through the brick walls? Does the sound actually penetrate the walls?
Apparently, this plays a large part in sound leakage. Simply stuffing air gaps between rooms (such as electrical outlet boxes that often bridge wall spaces) has a big effect on reducing sound leakage.RPinPA said:Another property that sound shares with other waves is diffracting around barriers.
The sound that gets through small holes between rooms is particularly annoying because it tends to consist of only the highest frequencies so you just hear a tinny sounds and the squeaky parts of kids voices - from one classroom into the staff room in school!DaveC426913 said:Apparently, this plays a large part in sound leakage.

Hearing through walls, also known as "wall listening" or "wall surveillance," involves using specialized equipment to detect and amplify sound waves that pass through walls. This can be achieved through various methods such as using a stethoscope, laser microphone, or even a smartphone app that utilizes the device's built-in microphone and sound processing capabilities.
The legality of hearing through walls varies depending on the country and state laws. In most cases, it is considered illegal to listen in on someone's private conversations without their consent. It is important to research and understand the laws in your area before attempting to use this technology.
Hearing through walls can be used for a variety of purposes, including law enforcement and surveillance, home security, and scientific research. It can also be used to detect potential structural issues in buildings or to locate and identify pests or other animals living inside walls.
The accuracy of hearing through walls depends on various factors such as the quality of the equipment used, the thickness and material of the walls, and the distance between the listener and the source of the sound. It is generally more effective in detecting lower frequency sounds and may not be able to pick up high-pitched or muffled noises.
There are definitely ethical concerns surrounding the use of wall listening technology. It can potentially invade people's privacy and violate their right to confidentiality. It is important to use this technology responsibly and with proper consent from all parties involved to avoid any ethical or legal issues.
