Sound is undoubtedly a very vital aspect of our existence. Other that being a major type of communication, it is also put to chore in geophysics when it comes to positioning, location and signaling.
As energy, it can be used to break down degas liquids and solids. Sound waves are caused by vibrations between molecules or atoms. These vibrations are transformed from kinetic energy to sound energy. It is this energy that allows the sound waves to be propagated.
In spite of its usefulness and vast applications, this type of energy is sometimes undesired and becomes an annoyance or hindrance. The motor engine noise, outdoor noise in a music studio, noise from a shared apartment etc. There is therefore requirement for a method or medium to block it or lessen it with sound isolation control products. As they are waves, sound energy can reflect, retract and move across edges. Though they can’t be completely blocked, they can be tremendously lessened. The way of eradicating, lessening or blocking sound is addressed as sound proofing, ...
... which can be done in the following three fundamental ways:

Damping: A type of absorption in which the oscillating sound waves are made to go through resonance, with respect to the surface it hits. Damping actually works best at low frequencies.
Absorption: Damping and absorption are complicated types of soundproofing, through the use of materials. In absorption, law enforcement soundproofing is accomplished by the lessening of the sound energy waves. When sound waves hit any surface, some gets transmitted through the material, some get absorbed in the material and a percentage gets reflected. The sound energy is transformed into kinetic energy through vibrations, and eventually to miniscule heat amount, through inter molecular friction.
Distance: While travelling through a medium, the sound energy of the waves is gradually lost after being transformed into vibrational energyin the atoms of the medium. Thus, the longer the distance, the waves to travel to reach the receptor, the more of its energy is lost.

One may imagine that law enforcement soundproofing can be accomplished by any material. This is nonetheless far from the case. There are some materials that can efficiently ensure soundproofing. Before analyzing some of these materials, we have to first get an idea about what properties make these materials unique. 
The ratings for collating and categorizing these different materials are the noise reduction coefficient, which is for absorbers and the sound transmission class (STC), which is for blockers. The NRC rating is between 0 and 1 and it’s an average of how absorptive a material can be at the four frequencies. As it is an average, two materials with the same NRC might work well at various applications. STC is a measuring stick regarding how well a material blocks sound.
