Sound Attenuation

Definition

Sound attenuation is the process in which sound is reduced as its energy is converted to motion or heat.

Purpose

The purpose of sound attenuation is to decrease the intensity of sound as it travels through materials or spaces, reducing noise pollution and improving acoustic comfort.

Examples of Use

• Insulation in walls and ceilings attenuates sound to prevent noise transmission between rooms.
• Sound barriers along highways reduce traffic noise for nearby residential areas.
• Industrial facilities use sound attenuating materials to protect workers from excessive noise levels.

Related Terms

• Acoustic Insulation: Materials used to reduce sound transmission and improve sound quality within a space.
• Noise Control: Techniques and methods used to manage and reduce noise.
• Damping: The reduction of sound energy by converting it to heat or motion.

Notes

Sound attenuation is critical in various applications, from building construction to environmental noise control, requiring the selection of appropriate materials and designs to achieve desired outcomes.
