An acoustician is someone who specializes in the study of sound. Many people mistakenly believe that acoustics is strictly musical or architectural in nature. On the contrary, acoustics is the interdisciplinary study of sound, and the field is very diverse, including people who study the production of sound, the physical properties of sound and its transmission in the environment or within enclosed spaces, and how sounds are received and used. These studies may focus on human-produced sounds, animal sounds, and/or sounds in the natural environment. Acousticians include engineers, physicists, speech and hearing scientists, doctors and medical researchers, architects, biologists, psychologists, mathematicians, oceanographers, computer scientists, and musicians. The application of acoustics is present in almost all aspects of life, including designing a concert hall, helping people with hearing impairments, investigating communication in marine animals, or researching the way in which sound travels underwater. Acoustician jobs can include opportunities for research in the field and/or a laboratory setting.
