A first type of acoustical waveguide filter, made of identical cavities, was developed and studied thoroughly. The noise control performance of that device was limited to a narrow frequency band. A new type of waveguide filter, made of rectangular cavities of different sizes, is proposed in order to
## Abstract An acousticβdriven thermoacoustic device, which is used to investigate acoustic characteristics of a regenerator, was designed and manufactured. A model of the acoustic characteristics of the regenerator is discussed. The acoustic characteristics of the regenerator, such as acoustic imp
