Sound Insulation and Sound Absorption Work<\/h1><\/div>Whether it’s due to living next to a road or in a condominium with poorly constructed walls where you can clearly hear your neighbors, we have to endure these noise disturbances for a long time. Wouldn’t it be great if we could eliminate these disturbances?<\/p>\n
At night, you wouldn’t hear street noise or neighbors arguing, and during storms, you wouldn’t be startled awake by thunder. It may sound like a dream, but it’s actually achievable.<\/p>\n<\/div><\/div><\/div>

Basic Concepts of Sound Insulation<\/h2><\/div>TL (Sound Transmission Loss)<\/strong> is the reduction in sound energy when passing through materials at different frequencies. TL values show how many decibels of sound a material can block at each frequency range.<\/p>\n<\/div>![\"SAC](\"https:\/\/3t-insulation.com\/wp-content\/uploads\/ROCKWOOL-TL.jpg\" "\\"ROCKWOOL-TL\\"")

STC (Sound Transmission Class)<\/strong> is the sound insulation rating of materials, derived from the average TL values. Higher STC values indicate better sound insulation. STC values cannot be added together. STC is determined through material testing, for example:<\/p>\n\n- 9mm gypsum wall with 50mm sound insulation has an STC of 35 <\/li>\n
- 10cm solid brick wall has an STC of 43 <\/li>\n
- 9mm sound-proof ceiling with 50mm sound insulation has an STC of 30 <\/li>\n<\/ul>\n<\/div>

Basic Concepts of Sound Absorption<\/h2><\/div>SAC (Sound Absorption Coefficient)<\/strong> is the sound absorption value of insulation at a specific frequency. SAC = 0.8 at 500 Hz means that at 500 Hz, this material absorbs 80% of sound and reflects 20%.<\/p>\n<\/div>NRC (Noise Reduction Coefficient)<\/strong> is the average sound absorption value of materials. For example, NRC = 0.8 means the material absorbs approximately 80% of sound overall and reflects 20%. NRC = 1 means sound enters and doesn’t exit at all, effectively absorbing 100% of sound.<\/p>\n<\/div>![\"TL](\"https:\/\/3t-insulation.com\/wp-content\/uploads\/ROCKWOOL-SAC-and-NRC.jpg\" "\\"ROCKWOOL-SAC-and-NRC\\"")

How do Sound Insulation and Sound Absorption Differ?<\/h2><\/div>Sound absorption and sound insulation have similar names but different applications.<\/p>\n<\/div>
Sound Absorption is<\/b> insulation material that absorbs sound to reduce echo and reflection. Its effectiveness is measured by SAC and NRC values – higher values indicate better sound absorption. It’s suitable for smooth-walled rooms without furniture, churches, meeting rooms, studios, and other spaces to reduce echo and sound reflection.<\/p>\n<\/div>Sound Insulation is<\/b> material that prevents sound transmission and reduces sound passage. Most are open-cell structure fiber insulations that must be used with wall panels or other wall structures. Their effectiveness is measured by TL and STC values – higher values indicate better insulation. Suitable for bedrooms, pubs, residential homes, office buildings, meeting rooms, and other spaces with noise issues.<\/p>\n<\/div>Comparison Table of Sound Insulation and Sound Absorption<\/strong><\/p>\n<\/div>\n\n
