In today’s rapidly evolving world, noise pollution has become an ever-increasing concern in urban spaces, industrial zones, and even residential areas. This noise pollution can have detrimental effects on human health, including stress, hearing impairment, and sleep disturbances.

What are the units of sound?
- Watt (Watt) or joule per second (J/s) is a unit of “sound power” (Power of sound wave) or the rate of energy transfer of a sound source per unit time, which is the sound we hear.
- Decibel is a unit of “volume” or “intensity”. Humans can hear sounds from 0 to approximately 120 decibels. If it is louder than 120 decibels, it can be harmful to the listener.
- Hertz (Hertz) is a unit of “frequency” of sound waves. It is an important factor for human hearing. Humans can receive sound waves with frequencies starting from 20 to 20,000 Hertz.
To understand soundproofing material, it is advised to firstly understand the key differences between Sound absorption and Soundproofing.
▫️Sound ‘Absorbing’ materials reduce the resonance and reverberation of sound waves within a space or room.
▫️Sound ‘Proofing’ materials prevent sound waves from passing in or out of the room.
Nowadays, there are various types of materials used to control or avoid noise following below.
As the world becomes more environmentally conscious. One such innovative approach is the use of “Sustainable Materials” as a sound-absorbing material.
