Summary

Chambers and resonators are used as noise control devices in almost all industrial duct systems. In Chapter 5, transmission loss is defined and, using the acoustic models and the assembly techniques described in previous chapters, transmission loss characteristics of various chamber and resonator types are demonstrated. Also discussed are the calculation of the shell noise and mean pressure loss (or back pressure), which may impose trade-offs on effective use of these devices in duct-borne noise control.
