I will always regret that I never met C.C. Bunch. I like to think of him as the very first audiologist. Toward the end of his life, he was a member of the faculty of my alma mater, Northwestern University, but he died three years before I entered the school as a freshman in 1945. He was well remembered by the older faculty, especially by voice scientist Paul Moore, who helped Bunch prepare his book, Clinical Audiometry, the first real tutorial on the techniques and interpretations of pure-tone audiometric testing.

What is ‘Normal’ Hearing?
Ask an audiologist what “normal” hearing is and, not surprisingly, you will get a variety of responses (Figure 1). Certainly, normal pure-tone threshold sensitivity does not rule out hearing difficulty or the presence of auditory pathology, including cochlear and auditory neural peripheral or central deficits. Further, a number of non-auditory factors can contribute to a patient’s perceived hearing difficulty (e.g., cognitive capacity, attention, medications, etc.).

Beethoven: His Hearing Loss and His Hearing Aids
The year 2020 is the 250th anniversary of the birth of the great classical composer, Ludwig van Beethoven (1770-1827). There is no authentic record of his actual date of birth, however the registry of his baptism in the Catholic parish of St. Remigius was on December 17, 1770.
To recognize this historical occasion, Perciaccante et al (2020) provide a review of Beethoven’s hearing loss and his use of hearing instruments of the time.
Coronavirus: Why We’re Investigating the Long-Term Impact on Hearing
Despite the multitude of ongoing research studies on COVID-19, there are many unknowns about the disease. What is known, however, is that it is more than just a simple lung infection.
Current research suggests that the respiratory system is not the lone organ system bearing long-term effects from the disease. COVID-19 may impact cardiovascular, immune, and nervous systems. Coronaviruses also may cause peripheral neuropathy or Guillain-Barré syndrome, both of which could result in auditory neuropathy.
The world of cochlear implants (CIs) is evolving. What was once a treatment pathway for a limited population of patients with profound hearing impairment has expanded to include individuals with moderate to severe hearing loss. CI technology, which began as basic sound processing through an electrode array, has grown to include Bluetooth streaming and cell phone connectivity.
