Sound Transmission through Flanking Paths

Sound transmitted through duct walls, floors and ceilings. Noise transmitted through duct walls, or through floors and ceilings with lower transmission loss - TL -, may dramatically diminish the effect of silencers and other acoustic enclosures.

Sound Transmission through Flanking Paths

Noise transmitted through duct walls, or through floors and ceilings with lower transmission loss - TL -, may dramatically diminish the effect of silencers and other acoustic enclosures.

This tool calculates sound transmission through flanking paths considering transmission loss through various materials and configurations.
