We begin this blog with a discussion of some basics and key concepts which will make it easier to understand some of the myths about hearing loss (“HL”) that make it so difficult for many lawyers to quit denying that they have issues that need tending and go in for a hearing test. Depending on the response of our readers, we may pursue exposing more of the myths for a while, discuss the latest headlines relevant to our topic or take up some other issues of interest, returning later to the myths. Some of the more current issues we may address include HL in the baby boomer population; noise-induced HL brought on by rock concerts, volume intense entertainment devices such as the i-Pod, and other sounds germane to a thriving and robust modern economy. Also of considerable interest are the latest advances in hearing aid technology and assistive listening devices which can help hearing challenged lawyers to stay competitive in the traditional areas of law practice where complete control over ones ability to perceive speech and understand subtext is critical to the proper handling of a client’s affairs.
With no slight intended, our blog is focused primarily on the issues confronting hard-of-hearing (“HOH”) lawyers who practice in the public and private sectors; serve as judges, or their clerks, on the state and federal benches; or hold positions in a legally related field such as legal education in the traditional law school setting. Too, it covers law school students and those who are considering a career in law.
The issues of those who were born Deaf, and others who were deafened later in childhood and use signing as their primary means of communication, are unique to that population and beyond the scope of matters we anticipate bringing to the table. However, the input of Deaf lawyers can be quite valuable and we welcome their comments on issues under discussion.
Our target is the population of lawyers who acquire HL during adulthood and communicate orally. Our purpose is eventually to educate them about the insidious dangers associated with undiagnosed and untreated HL that can upend careers in the prime of their professional lives. In doing so, we also hope to raise the level of awareness about hearing loss generally in the legal profession.
Perhaps most important, we will strive to quicken a sense of hope even to the most seriously affected, that there are options open to those who are willing to work through their denial and flexible enough to accept help from professionals who can assist them in re-gaining their functionality. It is especially important to note that the affected lawyer is not the only person at risk; in addition to families, co-workers and friends, the HL of challenged lawyers can also subject to unwanted outcomes, other lawyers working on same side of a case who may be following their lead; the firms, if any, who employ them; and most importantly, the clients they serve.
The human ear is far more complicated than one might think. It easily outperforms in range and sensitivity the most sophisticated sound systems ever devised. After reading the following brief description of how the ear interprets sound, one sees the complexity of the hearing process and should be able to understand why any deterioration or malfunction in the system can wreak havoc in a person’s ability to perceive and interpret speech. In a cavity containing a series of chambers, all well protected by cartilage and bone, there is a delicate, precisely tuned auditory mechanism through which sound impulses from the outside environment pass and are prepared for transmission to the brain. To illustrate briefly the complexity of the process, acoustic energy of the environment (think of it as a “message”) is perceived and funneled down the outside ear canal to the ear drum where it sets in motion a thin tympanic membrane covering the drum, converting the message from sound pressure to mechanical energy.
From that point, at the beginning of the middle ear, a process is initiated whereby the mechanical energy is converted to hydraulic energy after passing through the tiny ossicular bones in the middle ear to the cochlea. By the time it leaves the cochlea, another energy conversion has taken place and the message has become encoded with electrical energy. The acoustic nerve is the last point through which the message passes before entering the neural pathways which will take it to the brain for decoding into language that the brain can understand, and react, or not, as appropriate to the situation.
Many, if not most, people believe that HL is a manifestation of reduced loudness, as if someone turned down the volume on a radio. If only it were that simple we could have solved this problem years ago without the huge commitment of money for investment in technology. But, as we will discuss more in postings to come, HL is usually much more than a loudness issue. Some lawyers, most of them in denial, will attempt to shift the blame away from themselves by saying their HL is really someone else’s fault, “I hear just fine but others mumble, or talk too softly or too fast, and I can’t understand them.” True enough, this description is consistent with one type of HL known as “conductive hearing loss” (“CHL”) that can result in a reduction of loudness due to interference with the “conduction” of sound waves through the mechanical portion of the auditory system in the outer and middle ears. It mostly affects persons under age 20.
Examples would include the common cold, a wax build-up in the outer canal, or an ear infection which can interfere with the tympanic membrane’s freedom of movement when set in motion by sound waves coming into the ear from the outside, thereby resulting in a temporary HL. As adults, affected lawyers often experience another type of HL which can develop either on its own, or in conjunction with CHL. This second type, known as sensori-neural hearing loss (“SNHL”), results from a dysfunction of the inner ear, and is often referred to as “nerve loss.” SNHL can occur by itself, or co-exist with CHL in which case one could be said to have yet a third type of HL, i.e., a “mixed hearing loss”. SNHL is unlike CHL which generally is treatable medically or by surgical intervention; if for some reason a patient’s CHL is treatment- resistive, hearing aids can do a lot to compensate for the loss of volume. On the other hand, SNHL, resulting as it does from damage to the delicate hair cells inside the cochlea, is not so easily and economically treated. Once it sets in, the condition is usually progressive and permanent. In addition to some loss of loudness, the overriding result is a distortion of the signal such that nothing sounds clear any more. This manifestation is the main reason why persons with SNHL generally have more difficulty understanding speech.
Now having covered some of the basics, our next post will take up some of the “bumps” that can upset your hearing sensitivity and ability to perceive and understand speech. Beyond that general discussion, we are not licensed to assist you, but will be happy to discuss generally some treatment options and communication strategies available, and refer you to qualified hearing/speech specialists who will provide you with assistance that can help you stay competitive.
