An Open Letter to the Audiology Community
Behavioral audiology (BA) is based on a simple question: How do changes in an individual’s auditory status affect their overt and covert behaviors, specifically, but not exclusively, their receptive communication function? This leads to the corollary: What changes can we, as audiologists, effect in a client’s auditory behavior to improve their receptive communication function?
BA is now in its infancy as a clinical discipline but has its roots right back at the start of modern audiology following World War II when its focus was on the difficulties experienced by U.S. Veterans as a result of traumatic changes to their auditory status.
At that stage, knowledge of auditory function was basic, almost entirely based on the behavioral changes noted in people with abnormal pure-tone audiometry. There was little or no appreciation of the subtleties of the auditory process that have become apparent in greater detail recently, but nevertheless, audiological interventions were based on treating the Veteran’s receptive communication difficulties, as a behavioral audiologist might describe them now.
To understand how BA is different from conventional audiology practice, we must look very carefully at the phenomena with which are working. This close examination has not been carried out in the past (the early assumptions have not been challenged) and, as a result, there is a lot of confusion, both within and outside of our profession. Hopefully, you will see how BA can reduce this confusion as you read on.
We are dealing with highly complex phenomena, but our everyday language does not have well-defined concepts for us to describe these. The common language words such as hearing, especially, has multiple meanings. The jargon we have developed in audiology to describe these phenomena is very loose, and as we begin to uncover the complexities of our area, its inadequacy becomes clearer.
To escape this quandary, we need to re-examine the phenomena we are dealing with fresh eyes and develop very strict definitions. BA uses new definitions to help us with these complexities.
In a recent study, Mahendran and colleagues (2021) sought to compare the rates of cochlear implant (CI) referral and implantation across different races and to compare audiometric profiles of the patients via retrospective analysis. Demographic and audiometric data were collected for 504 patients between 2010–2020 who underwent CI evaluation or implantation. Of those, 388 met…
Should we provide cochlear implants earlier for children with large vestibular aqueduct syndrome? Patterson and colleagues (2021) examined outcomes of nine pediatric patients with Pendred syndrome who received cochlear implants between 2003–2017. Pendred syndrome is an autosomal recessive disorder defined by the combination of sensorineural hearing loss, goiter and an enlarged vestibular aqueduct (EVA). All…
Cochlear implantation is generally considered a safe and effective recommendation for healthy adults who have bilateral, moderate-to-severe or moderate-to-profound sensorineural hearing loss and do not benefit from acoustic amplification (i.e., poor speech recognition). However, given the large elderly population and the importance of timely hearing intervention, there is a need to more closely examine the…
