Types of Hearing Impairment and its Treatment

There are various factors which lead to loss of hearing, while ageing is considered to be the biggest cause of hearing loss it may also be congenital or may occur due to trauma. Hearing impairment can occur due to different reasons and is classified according to the type of malfunction, severity, extent of disability and stage of occurrence. Based on the above mentioned factors loss in hearing can be broadly classified into six major types: conductive hearing loss, sensory hearing loss, neural hearing loss, mixed hearing loss which is a combination of both, unilateral and bilateral hearing loss.

Prelingual deafness and Postlingual deafness is another parameter which decides the course of medication for hearing impairment. There are different hearing tests that determine the degree of hearing impairment and help the doctors in diagnosis and treatment, go check in this site whyaremyearsringing.co.uk, for more information related to hearing tests.

As the name conductive suggests, this type of hearing impairment is caused due to failure in conduction of sound waves from outer ear to the ear drum. This type of impairment is usually attributed to the malfunction of middle ear and is associated with reduction in the capacity to hear faint sounds.

Inner-ear disorders may cause hyperactivity

More info…
Behavioral abnormalities are traditionally thought to originate in the brain. But a new study has found that inner-ear dysfunction can directly cause neurological changes that increase hyperactivity. The study, conducted in mice, also implicated two brain proteins in this process, providing potential targets for intervention.

Auditory Training: Evidence for Neural Plasticity in Older Adults

More info…

Improvements in digital amplification, cochlear implants, and other innovations have extended the potential for improving hearing function; yet, there remains a need for further hearing improvement in challenging listening situations, such as when trying to understand speech in noise or when listening to music. Here, we review evidence from animal and human models of plasticity in the brain’s ability to process speech and other meaningful stimuli. We considered studies targeting populations of younger through older adults, emphasizing studies that have employed randomized controlled designs and have made connections between neural and behavioral changes. Overall results indicate that the brain remains malleable through older adulthood, provided that treatment algorithms have been modified to allow for changes in learning with age. Improvements in speech-in-noise perception and cognition function accompany neural changes in auditory processing. The training-related improvements noted across studies support the need to consider auditory training strategies in the management of individuals who express concerns about hearing in difficult listening situations. Given evidence from studies engaging the brain’s reward centers, future research should consider how these centers can be naturally activated during training.
