Suspect a Hearing Loss? Make an Appointment with an Audiology Clinic in Knoxville, TN

While advanced age is the most frequent reason for a hearing loss, noise also factors into the equation. People who are between 65 and 74 years old are often seen by audiology doctors with the number increasing after the age of 75. Scientists do not fully comprehend why a person’s hearing worsens with age. However, they usually conclude that the reason is both hereditary and due to long-term exposure to noise. Ongoing Exposure to Noise at Work Noise is indeed a factor that must be reviewed when a person sustains a hearing loss. When you visit an audiology clinic in Knoxville, TN, you will find that noise as well as medications can have adverse effects. For example, your hearing will suffer if you are exposed to excessive noise levels at work. Some of the areas in which people suffer the most loss of hearing include carpentry, plumbing, mining, manufacturing, transportation, agriculture, and the military. Medicines That Reduce the Ability to Hear In other cases, audiology clinic specialists often see patients who work in the musical field. Performers such as singers or musicians should always wear earplugs when they are on the stage. Medications, as noted, can also have an adverse impact on the hearing. For example, drugs such as aspirin, antibiotics, chemotherapy medicines, and malaria medications can all reduce a person’s ability to hear. A Sudden and Unexpected Loss of Hearing In addition, audiology clinic doctors add that some people may experience a hearing loss suddenly. When this happens, a loss of 30 decibels can occur over a span of days. In most of the cases, the loss only impacts one ear. While about 4,000 new cases of this type of malady happen annually, physicians only determine the cause about 10% of the time. Infection or a buildup of earwax can affect the hearing as can trauma or an illness such as high blood pressure, diabetes, or heart disease. Diseases of the middle and inner ear can also lead to a hearing loss problem....

Hydrophobic Coatings and Hydrophilic Coatings: Differences between the Two

Apr 11, 17 Hydrophobic Coatings and Hydrophilic Coatings: Differences between the Two

Posted by in Medical education‎

When it comes to implant device coatings, there are two types applied to reduce the friction between the device as well as the surrounding tissues and blood vessels as much as possible. These coatings are hydrophobic and hydrophilic coatings. Wondering what differentiates one from the other? Read on: Hydrophobic These refer to coatings that repel polar substances. One good example of those substances is water. That’s why it’s also called water-fearing coatings. This is the kind of coating you’ll typically find in vapor as well as liquid protective coatings. These coatings are not as lubricious as well, so that’s a helpful quality to keep in mind to help you differentiate between the two coatings. Hydrophilic These coatings, on the other hand, interact with polar substances and become more lubricious after the contact. They’re well-known for attracting water to the surface, keeping the water flat and preventing them from beading up. They are also known to be a self-cleaning coating. Both coatings help doctors perform minimally invasive medical procedures. Making the surface of the implant devices lubricious with these coatings significantly cuts down on health risks and issues, along with any infection that could happen, says the FDA. Which option should you choose? Depending on what your needs are, hydrophilic coatings might work better for you or vice versa. If you want something an option that’s suited for industrial flexibility or one to create more clarity as well as resistance to scratches and impact, then a hydrophobic coating might be the better option. However, if you need coatings that will stop water from beading up, comes with self-cleaning capabilities that create an oxidizing effect to ensure dirt and contaminants are repelled, then opting for coatings that are hydrophilic in nature might offer a much better solution. Determine what kind of coating you need to help you pick the best option...
