How Directionality Works
Localizing sounds or identifying the direction they come from, is primarily made possible by having two ears, separated by our head. Just like having two eyes improves depth perception, input from two ears improves our ability to comprehend speech in noise. A person with normal hearing in both ears has a better chance of understanding speech-in-noise than a person with perfect hearing but only one ear.
The link between heart disease and hearing health has been confirmed by numerous scientific studies in recent years. The connection seems to come from the small but required amount of oxygen rich blood circulating through the inner ear. When cardiovascular health problems cause even minute changes in the heart’s efficiency, it can be reflected in a person’s hearing health as well. As such, a loss of hearing sensitivity can be one of the earliest symptoms of heart disease.
It’s no secret that untreated hearing loss can have a negative impact on quality of life. This is the unfortunate truth for more than 33 million Americans. It is also a sad reality that a large portion of those 33+ million people leave their condition untreated for the simple reason that they cannot afford hearing aids.
Did you know that more than 200 types of common over-the-counter and prescribed drugs and chemicals can damage your hearing? Aspirin, which lurks on a shelf in most people’s bathroom cabinets, is one of them.
Known as ototoxic, the adverse effects of these medications usually starts with ringing in the ears and/or loss of balance. More severe reactions, such as permanent hearing loss, occurs when ototoxic medications are taken in high dosages or over a long period.
For many people, the holiday season is full of family traditions deeply rooted into their minds by a lifetime of celebrations and quality moments. Fond recollections of loved ones and special times over the years have systematically been stored into pockets of cognitive recall deep inside the brain. These are more commonly known as memories.
According to the September 2015 PCAST report on the state of hearing technology, there are still millions of Americans with hearing loss that do not buy hearing aids because they simply cannot afford them. This is the bad news, and is truly an injustice to people who are simply hoping to hear better.
An earhook and thick tube combination are often used when a hearing aid needs to deliver more sound to the ear than the typical standard thin tube can produce. The logic is simple – the thick tubes have a greater diameter of tube available which allows more sound to transmit to the ear. The earhook is simply an adapter that allows for the thicker tube to connect with the hearing aid.
