Sound Insulation/ Acoustic Insulation

Sound Insulation / Sound Proofing
Sound insulation is a kind of measure to prevent the sound waves from permeating. It is demonstrated by the sound transmission loss which is expressed by the difference of decibels between the incident sound and permeated sound. The higher the numeral is, the better the sound insulating property is.

Materials used: -
