Understanding the Differences Between Pre- and Post-Natal Hearing Loss

...

Those individuals born with full hearing, just like myself, then suffer a devastating hearing loss at an early age due to various factors, often bear stark differences in their speech and communication abilities as compared to those who are born deaf. This article aims to elucidate the nuanced distinctions between the two scenarios based on personal experiences and medical insights.

Uncovering the Imprint of Hearing Loss

Most likely, individuals born deaf do not have any imprint of spoken language on their brains, making speech therapy an extraordinarily challenging endeavor without any prior experience. Interestingly, research indicates that children acquire all knowledge and usage of spoken language during the first 12 months of life. Therefore, those who lose their hearing in early infancy, like myself, managed to avoid this significant challenge.

While I cannot remember what it's like to hear, my body retains enough 'cell memory' to allow me to imagine how to pronounce words accurately. This innate ability often distinguishes those born deaf from those who acquire deafness later in life. The former, having never experienced spoken language in their developmental years, have a unique accent or way of speaking that may not be as easily recognized or processed by the hearing individuals around them.

The Uniqueness of Accents in Deafness

Notably, people born deaf often exhibit a unique accent that those who become deaf later in life do not share. My encounter with strangers who automatically use sign language upon hearing my voice supports this observation. Despite my proficiency in lip reading and my lack of knowledge in sign language, my distinctive vocal tone and cadence allow for such misunderstandings.

Understanding the Origins of Hearing Loss

Congenital hearing loss, that is, hearing loss present at birth, can result from a myriad of factors, including genetic factors, prenatal exposure to infections or drugs, complications during birth, and maternal health issues. Conversely, acquired hearing loss, which occurs later in life, can be caused by factors such as aging, noise exposure, infections, head trauma, and medical conditions like otosclerosis or Menières disease.

According to medical insights, some individuals, like me, may have had a degree of hearing loss in one ear due to an illness, such as measles, during childhood. Over years, the condition may progress, leading to severe hearing impairment by older age due to other health factors, such as narrowed arteries in the neck and head.

Experiences of Others with Hearing Loss

It is worth noting that there are a multitude of causes for both congenital and acquired deafness. As a case in point, a friend of mine, who was a professional roadie for heavy metal bands, suffered severe hearing loss due to constant exposure to the high decibels produced during live performances. The combination of multiple factors, from genetic predispositions to occupational hazards, underscores the complexity of hearing loss.

Conclusion

While both congenital and acquired hearing loss present unique challenges, those born deaf who experience a later-in-life loss often possess a distinct perspective and capability to adapt compared to those who are born deaf. Understanding the nuances between the two can provide valuable insights into the nature of hearing loss and guide more effective strategies for support and rehabilitation. The medical and personal insights shared here offer a multifaceted view of this complex issue.
