The ear contains several membranes and nerves that are prone to infection, obstruction and trauma. Even minor head injuries may damage the structures that comprise the auditory pathway. When hearing is disrupted, external electronic devices might be necessary to support auditory transmission. Thus, more people buy hearing aids to amplify sound for better listening and understanding.
Who is at Risk for Developing Hearing Loss?
Chronic hearing loss primarily occurs due to disseminated infection, accidents and constant exposure to loud sounds. Pilots, welders, musicians and carpenters develop higher incidence of hearing loss due to increased noise exposure. Military veterans also have higher risk of auditory impairment due to head and inner ear injury. Thus, specialized hearing aids for veterans and welders are available to ensure proper sound transmission based on the deformed structure.
How do Hearing Aids Work?
Hearing aids come in different styles, but they usually have three main components — the microphone, amplifier, and speaker. The microphone is responsible for receiving and converting sounds to electrical signals to the brain. The converted vibration is transmitted to an amplifier, which increases auditory intensity to reach the threshold for audible sounds. High intensity sound is processed until it reaches the ear through a speaker.
When Should I Wear a Hearing Aid?
If you are experiencing mild symptoms of hearing loss, you must visit an audiology expert who can determine the extent of impairment. Basic auditory assessment, such as Weber and Rinne tests, are done to initially assess if hearing difficulties are present. Once the pathology is confirmed, audiometry tests are conducted to check the degree of hearing loss. These tests are essential for proper management of the condition.
Proper hearing plays an important role in effective communication. Therefore, you should not let hearing impairment hinder your daily activities. Hearing aids may serve as long-term solutions to improve auditory capacity, noise filtration and speech comprehension. As a result, you gain confidence to speak and assert yourself during conversations with others.
