To increase the sound insulation effect of the space, should we choose Sound-absorbing Nonwoven Fabric or Sound-insulating Nonwoven Fabric? How to solve the problem of excessive echo? Only by understanding your own needs can you purchase suitable products, so before placing an order to buy Sound-absorbing Nonwoven Fabric or Sound-insulating Nonwoven Fabric, you have to know the differences between them.

    This article takes you through the definitions of sound absorption and sound insulation, and their material differences, helping you distinguish the effects of Sound-insulating Nonwoven Fabric and Sound-absorbing Nonwoven Fabric in order to choose ideal sound absorption or sound insulation materials.

   What are the differences between Sound Absorption and Sound Insulation? Different effects meet different needs.

    Sound absorption and Sound insulation are two easily confused concepts. To improve the noise problem in a space, it is necessary to first understand the differences between the two in order to understand your own needs.

    Sound Absorption: Absorbing sound energy from the space

    Absorb sound energy in the space, reduce sound reflection, and improve indoor noise, echo, and reverberation issues. For example, when you fill a room with Sound-absorbing Nonwoven Fabrics or Sound-absorbing Boards, the sound will be absorbed when it hits the Sound-absorbing Nonwoven Fabrics or Sound-absorbing Boards, avoiding sound reflection as well as reducing the echo of recording, playing music or watching videos.

    Sound Insulation: Blocking sound penetration

    Avoid sound coming out or in, and reduce sound interference between two spaces. When staying in a hotel, it is easy to hear the sound of the next door talking; or being protested by neighbors while playing music at home; these are usually due to poor sound insulation in the space, so it is necessary to strengthen the sound insulation to avoid disturbing each other.

   What are the differences between Sound-absorbing Nonwoven Fabric and Sound-insulating Nonwoven Fabric?

   Although there are many choices for sound-absorbing materials and sound-insulating materials, they generally possess the following characteristics:

    Characteristics of sound-absorbing materials:

    Sound-absorbing Nonwoven Fabric, with a low-density and uneven structure, is often designed as a fibrous or granular surface which can increase the frictional force on sound waves, thereby absorbing the energy of sound waves. After absorbing sound, materials with good sound-absorbing effects can prevent sound transmission after absorbing sound, and reduce the interference of sound on the external environment, so they have a certain degree of sound insulation function.

    Characteristics of sound-insulating materials:

    Sound-insulating Nonwoven Fabric, with a high-density and flat surface, can effectively block the transmission of sound waves, allowing sound to stay in a single space; but also due to the smoothness of the surface, sound-insulating materials are often prone to sound reflection, causing indoor echo problems.
