It absorbs, diverts & dampens the sound and does a pretty efficient job at it.
When the waves hit something that is smooth, hard and or with minimal surface area it gets diverted but not reduced by much.
When the sound waves hit something soft that bends or a surface with a lot of surface area it absorbs much of the energy in the waves.
The other effect that works well to mitigate sound is to divert the energy into many directions. Same energy, many directions instead of just one & the vibration is much diminished.
Carpet is both soft & full of millions of individual fibers that absorb & divert the sound. Many of your favorite albums were made in studios that had shag carpets on the walls for this very reason; it helps the sound engineers get that distinct studio dead sound.
Many performers stand on an oriental rug when they sing, same effect & reason.
The acoustics in the lecture room are terrible.
The word is "acoustics." Acoustics refers to the qualities of a room or hall that affect how sound is transmitted and heard within that space.
The absorption of sound waves in a room affects its acoustics by reducing echoes and reverberations, leading to clearer and more balanced sound quality. Materials like carpets, curtains, and acoustic panels can help absorb sound waves and improve the overall acoustics of a room.
It depends on the size of what you're carpeting.
290 dollars for the carpeting.
16 square yards. Carpeting is sold by the square yard.
810.60 for the carpeting.
Reverberation echo is the persistence of sound in a room after the original sound source has stopped. It can affect the acoustics of a room by creating a prolonged and sometimes muddled sound, which can impact clarity and intelligibility of speech or music.
Simulating acoustics is the process of modifying your sound in post-production, in order to portray how you want your sound to sound like. For example, when you record your sound in a sound proofed recording suite/room, where the sound cannot bounce, but you wish to make it sound like you're in an empty church, you would have to add reverberation to the sound in order to gain this effect. The process of adding the reverberation is simulating the acoustics of an empty church. This is called Simulating Acoustics.

Maybe just the celing and floor?
yes, they use math to calculate the area for the room.
