Sound Attenuation - Duct split to Terminals

Estimation of sound attenuation when ducts are split to terminals

Sponsored Links

Splitting ducts to terminals will reduce the sound power level - LN - transferred to each terminal.

Sound allowance - lw split branch terminals

The sound power is reduced according reduced volume of air.

For equal terminals the attenuation to each terminal is indicated in the diagram below.

Duct to Terminals - Sound allowance

Example - Sound Attenuation from a Duct to Equal Terminals

According the diagram above - for a duct that splits into four equal terminals the sound attenuation from duct to each terminal is approximate

6 dB
