Structural Borne vs Airborne Noise

Structure-borne sound and airborne sound are two different types of sound transmission mechanisms.
1. Airborne Sound:
• Airborne sound is the most familiar type of sound transmission, occurring through the air.
• When an object vibrates, it displaces the air molecules around it, creating sound waves that propagate through the air.
Examples: conversations, music, and noise from machinery.
2. Structure-borne Sound:
• Structure-borne sound, as the name suggests, travels through solid structures.
• It occurs when an object vibrates and transfers its energy directly to the structure it's in contact with.
• The structure then vibrates, transmitting the sound energy through it.
Examples: footsteps on a floor, vibrations from, or sound through shared walls.
Understanding the distinction between these two types of sound transmission is essential for addressing noise-related issues in various environments, whether it's for architectural design, noise control, or product development.
