At this time, I'd like to express my heartfelt gratitude to everyone who has helped, supported, and cared for me during these four years. I'd like to express my sincere thanks to Prof. Gan Woon Seng, my Ph.D. supervisor, for his care and support throughout my studies. His enthusiasm for research and commitment to it has profoundly impacted me. Prof. Gan created a pleasant research environment and gave me valuable life advice. Thanks to Prof. Gan's thorough guidance, I've learned much about the fun and importance of research work. I'd like to use this opportunity to express my appreciation to my senior, Dr. Shi Dongyuan, who has been a tremendous help to me since the beginning of my research. He has actively guided my studies and experiments. With his assistance, I've made significant progress. Ms. Santi Peksi assisted me in learning about local customs and doing many lab tasks. Wen Shulin (Dr), Lam Bhan(Dr), Keneth, Karn, Hai, Zhen Ting, Tho, Rishabh, Miqing, Zhengding, and Junwei were all important members and alumni of the lab throughout my Ph.D. I want to thank my three best friends in China, Zhou Yilin, Jin Jun, and Wen Jiafen, in particular. They showed me a lot of love and encouragement when I was down or upset. They also assisted me in caring for my family. Junjie, Hanxiao, Xiaofan, Mingyu, Yuncheng, Ruiyu, Yuhao, Suofei, Zhangxin, and Mengmin were among my friends in Singapore, and I am grateful for their support in my studies and daily life.Finally, I wish to express my warmest gratitude to my parents, Mr. Liu Zhen and Mrs. Shen Heyin, as well as my grandma, Mrs. Sun Qiuyun. They were always there for me no matter what I did or said. I love all of you!

A tunable active-noise-control (ANC) circuit topology for headsets used in different applications is presented in this article. In the current consumer headset market, ANC is a mature technology that is commonly applied to wireless headsets connected to smartphones for listening to music and making phone calls. The development of ANC headsets has resulted in low-cost and simple devices due to the built-in ANC registers in the digital circuit. Digital circuit implementation is important to provide ultra-low latency processing for different algorithms compared with using digital signal processors (DSPs). However, a limitation associated with these built-in ANC filters is that the ANC digital circuit has been designed only for the wireless headset consumer market. Consequently, ANC headsets can only be used for designated features. ANC tuned for planes by eliminating low-frequency engine noise has been commonly used in the past twenty years. Pass-through (PT) amplification is also commonly tuned to allow users to hear external sounds and have conversations without having to remove their headset. In addition, ANC and PT amplification are also not allowed to operate simultaneously on the existing chipsets. In this paper, an ANC circuit topology with ultra-low latency processing is presented, where the ANC response of the headset can be tuned without any restriction imposed by the built-in ANC filters. The proposed ANC circuit topology consists of a commercial ANC chipset with an external audio codec to provide tunable characteristics. It is achieved by fixed maximum noise cancellation of ANC chipset being modified by summing with the signal from audio-codec path via an audio mixer. Acoustic performance for several headset applications implemented using the proposed circuit is validated. This simple circuit topology can be easily developed and adapted to the current headset consumer market for consumer-selective ANC in different environments.
