Anil Lalwani, MD, professor and vice chair for research in the department of otolaryngology–head and neck surgery at Columbia University College of Physicians and Surgeons in New York City and the current president of the American Auditory Society (AAS), introduced a session focused on important new research and knowledge in hearing loss. He noted that the research presented in the session would point to a need to refine how to test for hearing loss.

Hearing Decline Begins Much Earlier than Commonly Thought
Sumitrajit Dhar, PhD, chair of the department of communication sciences and disorders at Northwestern University in Evanston, Ill., began his talk by explaining, “We know that at some point in our lifetime, auditory function starts to decline.” He added that the real question is when the decline begins, and one barrier to answering this question has been the lack of sound sources that deliver clean but adequately intense signals to evaluate the parts of the inner ear that are responsible for capturing the highest audible frequencies.
Another barrier to evaluating the cochlear base in routine clinical or research protocols has been the inability to accurately calibrate sound levels at high frequencies.
