Yes, particularly if they contain calcium silicate filler.
Because of air damping.
Very little sound will escape the room.
Damping makes a sound weak and amplifying makes it strong.
the amplitude of a sound wave makes sound loudness and softer.. damping makes a sound weak and amplifying makes it strong
Spiky or wavy surfaces have the effect of damping sound. Snow is spiky if you look through a microscope at it.
Damping in a vibrating system causes a decrease in amplitude because it dissipates energy from the system in the form of heat or sound. As energy is lost to damping forces such as friction or air resistance, the system's natural frequency is reduced, leading to smaller oscillations over time.

Green Glue damping compound was created as a soundproofing materials. It works because it has visoelastic properties that make it great at both absorbing and blocking sound. Green Glue is usually sandwiched between two rigid layers of material, like drywall. Sound is then unable to pass through the wall (or whatever object you soundproofed).
The pitch is determined by how high the sound is.
The two properties of a sound that get louder are its amplitude, which determines the volume or intensity of the sound, and its energy level, which increases as the sound becomes louder.
Sound powder in Tamil is referred to as "சவம் பொடி" (savam podi).
A scientist who studies sound is known as an audiologist. Audiologists study patens that sound waves make as well as the effects of certain vibrations on the human body.
