Dr. Tang-Chuan Wang is an excellent otolaryngologist-head and neck surgeon in Taiwan. He is also a research scholar of Harvard Medical School and University of Iowa Hospitals. During his profound experience, he has worked in the Hospital of the University of Pennsylvania, Boston Children's Hospital, and Massachusetts Eye and Ear. Besides, he is not only working hard on clinical and basic medicine but also launching out into public

health in Taiwan. In recent years, he has devoted himself to medical innovations and telemedicine. He always says that "in theoretical or practical aspects, no innovation is a step backward." Due to his contribution to bio-design, he was invited into the executive committee of HIWIN-CMU Joint R&D Center in Taiwan.

Preface

The auditory system is one of the finest structures in the human body. Although the auditory anatomical structure is so small compared to other organs, without it, it would greatly affect a person's basic life. Hearing loss, also known as hearing impairment, is a partial or total inability to hear. When people communicate with others, listening is always the first step. That is why Helen Keller once said, "Blindness separates people from things; deafness separates people from people."

**Noise-induced hearing loss**, a common cause of hearing loss, is a kind of hearing impairment resulting from exposure to loud sound. There is continuous and endless noise in many workplaces, which may cause chronic and cumulative damage. Some young people often work hard, but they easily neglect or forget to protect themselves. This type of hearing loss is avoidable and preventable. In the section "Teamwork Approach to Noise-Induced Hearing Loss, Dr. Alberto Behar talks about noise exposure. The question to answer is how to determine the risk of a person performing in an environment where the noise levels, duration, and frequency content change with time. Dr. Joong-Keun Kwon and Dr. Jiho Lee introduce the scientific basis of noise-induced hearing loss, the impacts of ototraumatic substance, and the co-existing impact on hearing loss. In addition, Dr. Alejandro Brice provides a case study from a speech-language pathologist's perspective and discusses the occurrences that affected comprehension along with the compensatory strategies that

**Hearing loss** in children is a problem worthy of attention. Around 7% of the people with disabling hearing loss are children, and it is very worrisome to note that 5 out of every 1000 infants are born with or develop disabling hearing loss in early childhood. Hearing loss can affect a child's ability to develop speech, language, and social skills. I have managed children with hearing loss for many years, and the most touching sight is the light that blooms on a child's face when hearing his or her mother's voice for the first time. Then the scene of "happy tears" impressed me so much. To hear the voice that has not been heard is so pleasant, as if this ordinary listening experience is a supreme listening enjoyment. In the section "Teamwork Approach to Hearing Loss in Children," Dr. Alejandra Itzel Contreras Rivas et al. present neonatal hearing screening. It is very important to screen all newborns in order to establish the appropriate diagnosis and the necessary treatment to avoid delays in development. Dr. Penelope Brock et al. discuss cisplatin ototoxicity in children. They focus on cisplatin-induced hearing loss, its mechanisms, its health impact on the young

person, and ways to mitigate or reduce the severity of ototoxicity.

**Hearing loss comorbidities** is a term that means that a person's hearing health is affected by other medical conditions and vice versa. In the section "Teamwork Approach to Hearing Loss Comorbidities," Dr. Sampson Antwi and Dr. Mohammed Duah Issahalq share the topic of hearing loss in chronic kidney disease. Hearing loss is not uncommonly associated with chronic kidney disease and this comorbidity is often overlooked by health caregivers. Dr. Rajesh Paluru and Dr. Devendra Singh Negi investigate brainstem auditory evoked potentials in type 2 diabetes mellitus. When brainstem auditory evoked potentials were carried out in diabetic patients
