Abstract: Acoustic resonators are widely used in various noise control applications. Working in a narrow frequency band, their physical characteristics, i.e. the resonance frequency and damping affect the control performance. To achieve good performance, these parameters need to be fine-tuned, which requires an accurate theoretical model of resonators. Existing models on T-shaped acoustic resonators, however, fail to meet this requirement. In this paper, a three-dimensional model for T-shaped acoustic resonators is developed by considering multiple acoustic modes. The resonance frequency is then determined and compared with numerical simulations from Sysnoise and experimental results. The proposed model is shown to be able to provide accurate and reliable prediction of the resonance frequencies of T-shaped acoustic resonators.
