Certain Sounds Cause An Extremely Negative Reaction To People    

It Can Produce Anger, Anxiety, And Even Hypertension And Higher Heart Rate    

There is a condition in which people react negatively to certain sounds. It is called misophonia, in which people overreact to determinate sounds, such as slurping drinks, tapping the fingers, or keyboard clicks, among others. Their reaction is disproportionate, and people are aware that they cannot control it. According to specialists, this aversion develops in childhood and gets worse over time. The reaction includes emotional responses, such as anger and anxiety, and also physiological responses, like hypertension and higher heart rate. It can also be caused by other conditions, such as tinnitus, OCD, or eating disorders. Consequences on sufferers include avoiding social situations and broken relationships.

Explaining The Shape Of Human Ears    

Many of us wonder why our ears are shaped the way they are. Human ears are fixed, unlike the rotating ears of many animals. Also, they are optimized for hearing from the front since the outer flap works like a sound-gatherer. Click here for more information.

 

Researchers Have Developed A Technique To Deliver Drugs To The Inner Ear

Researchers Have Developed A Technique To Deliver Drugs To The Inner Ear    

Its Closed Space Makes Difficult Targeting Drugs And Meds    

There are several types of research on drugs to improve hearing or to slow down the hearing loss, and many of them are oriented to the inner ear, the cochlea, or the hair cells that detect sound and transmit it to the auditory nerve. However, even the drug has had positive results on the lab, the main problem is the drug delivery, due to the fact that the inner ear is a very small space near the brain, and the fluids in the inner ear are always moving. A recent research has figured a new way for drug delivery, targeting the cochlea. It combines the drug with a molecule that mimics a protein essential for the development of the nervous system and to a substance that sticks to the bones. Additional details click here.

 

Smoking Increases The Risk Of Hearing Loss

Smoking Increases The Risk Of Hearing Loss    

It Affects Hearing Low And High-Frequency Sounds    

In a study in smokers which included 50,000 participants, researchers found that they had an increased risk of hearing loss compared to non-smokers. Also, smoking affected the hearing of high-frequency sounds more than low-frequency sounds. However, the risk of hearing loss in both types of sounds increased with cigarette smoking. Also, they found that quitting has its benefits, since the risk of hearing loss decreased after 5 years. More details click here.

Frequent Use Of Magnetic Resonance Scanners (MRI) Increases The Risk Of Hearing Loss

Frequent Use Of Magnetic Resonance Scanners (MRI) Increases The Risk Of Hearing Loss    

More Powerful Models Have More Magnetism, But Also Generate Higher Noise    

Magnetic resonance imaging has given physicians the possibility of visualizing the brain, spinal cord, and other body parts, allowing an early diagnosis of serious conditions. However, it has a downside for the patient, and it is the noise of the modern scanners can reach a peak sound of 125.7 to 130.7 dB, with an average between 110 to 115 dB. This sound level can result in tinnitus and noise-induced hearing loss. MRI scanners with a higher level of magnetism have a higher noise level. Also, the scanners generate low-frequency sounds, less than 1 kHz, which have less risk of hearing impairment than higher frequency sounds, higher than 4 kHz. In these cases, the suggestion is to wear earplugs to attenuate the sound. More Information click here.

 

Nerve-Related Hearing Loss Can Be Restored By Treatment

Nerve-Related Hearing Loss Can Be Restored By Treatment    

A condition called neurofibromatosis type 2 or NF2 causes growth of tumors in the nervous system. These are not cancerous but affects the nerve function. The most common is the one affecting the auditory nerves. It can be removed by surgery, but there is a risk of damaging the nerve. Now there is a drug that can treatments, reducing the tumors.
