Sound insulation | PPT
Sound insulation is the process of soundproofing an enclosed space to prevent sound from filtering in or out. Various materials can be used for sound insulation like fiberglass wool, rock wool, glass wool, mass loaded vinyl, cork, green glue and foam panels. These materials work by absorbing, reflecting or damping sound vibrations.

Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
