Headphones and Hearing Loss

Hearing loss affects countless consumers as they enter into older age, and previous studies have warned about how the condition can lead to premature death.

Now, researchers from University College London have found that a gene in fruit flies could be the key to treating hearing loss for older consumers. Because of how similar fruit flies’ auditory processing is to humans, these advances could greatly benefit consumers with hearing loss. 

“While many studies have been conducted into the hearing function of fruit flies, ours is the first to look at the mechanistic and molecular detail of their auditory life course,” said researcher Joerg Albert. 

“Our twin discoveries that fruit flies experience age-related hearing loss and that their prior auditory health is controlled by a particular set of genes, is a significant breakthrough. The fact that these genes are conserved in humans will also help to focus future clinical research in humans and thereby accelerate the discovery of novel pharmacological or gene-therapeutic strategies.” 

Treating hearing loss

Fruit flies were chosen for the study because of how similar they are biologically to humans. During this study, the researchers found that fruit flies experience hearing loss as they age much in the same way that humans do. 

In learning that, the next portion of the study involved the researchers retracing their steps. They sought to discover if there was any genetic indicator that could have prompted them to know that hearing loss was likely in the fruit flies. 

They discovered that the fruit flies had homeostasis genes, which are often responsible for picking up on sound and overall sensitivity in the ear. Knowing that, the researchers then got to work altering the gene expression, by making the genes either more or less prominent in the fruit flies, to determine if that affected their hearing loss. 

Ultimately, the researchers learned that manipulating the genes in this way was helpful in treating hearing loss for the fruit flies. Their findings from this study could help spur future treatment plans, and they could be the key to improving hearing loss treatment in the future. 

“Based on our findings from [the fruit flies], we have already started a follow-up drug discovery project designed to fast-track novel treatments for human [age-related hearing loss],” Albert explained.

Happy Plugs of New York is recalling about 9,400 Happy Plugs Bluetooth Wireless II Headphones sold in the U.S. and Canada.

The micro-USB charging cable packaged with the headphones can cause the headphones to overheat, posing a burn hazard.

The firm has received one report of the headphones overheating while plugged into their micro-USB charging cables. No injuries have been reported.

This recall involves Happy Plugs Wireless II Bluetooth Headphones sold with an external micro-USB charging cable.

The micro-USB charging cable is a black cable about 20 inches in length with a USB 2.0 port on one end and a micro-USB port on the other.

The UPC is printed on the back of the product packaging in the lower right corner and the item number is printed on the bottom of the product packaging.

The following headphones are included in this recall:

The headphones, manufactured in China, were sold at Macy’s stores nationwide and online at happyplugs.com from January 2019, through May 2019, for between $10 and $40.

What to do

Consumers should immediately stop using the recalled headphones and charging cable, and return them to the place of purchase or contact Happy Plugs to receive free replacement headphones and charging cable.

Consumers may contact Happy Plugs at (800) 419-2988 from 9 a.m. to 5 p.m. (PT) Monday through Friday, by email at customerservice@happyplugs.com and include “Recall” in the subject line, or online at https://happyplugs.com and click on “Support,” at the bottom of the page, then “Warranty and Returns,” then click on “Voluntary Recall and Exchange Program.”

Strategic Sports is recalling 1,956 Motovan Zox Sierra helmets, part number ST-560, in sizes XS, S, M, and L.

The helmet shell may allow an object to penetrate through to the users head. As such, in an event of the crash, the helmet may not protect the occupant, increasing the risk of injury.

What to do

Strategic Sports has notified the distributors and known owners, and will provide refunds for all consumers returning their helmet.

The recall began May 1, 2019.

Owners may contact Moto customer service at (888) 449-7773 or by email at helmet.recall.info@gmail.com .

Not too many consumers want to think about getting older; however, a new study conducted by researchers from the University of California - San Diego may have people planning for the future.

Researchers found that hearing loss is one of the first signs of advanced aging, and it could lead to cognitive difficulties in old age. However, according to the study, higher education can help with mild hearing loss.

“We surmise that higher education may provide sufficient cognitive reserve to counter the effects of mild hearing loss, but not enough to overcome the effects of more severe hearing impairment,” said Linda K. McEvoy, PhD.

Fighting hearing loss

The researchers note that nearly 75 percent of adults over the age of 70 experience hearing loss, and they used this study to try to help combat any other aging issues that could come along with that.

Using a longitudinal study, the researchers followed over 1,100 participants for about two and a half decades. The majority of the participants were women, and the average age was roughly 74 years old.

None of the participants used a hearing aid when the study began, and they all had their hearing tested at the outset. Five additional examinations were conducted during the study period -- typically every four years.

At the start of the study, the participants also completed several tests to analyze their cognitive functioning, and the researchers found that those with more severe hearing loss didn’t perform as well on these tests as those with more mild hearing loss.

The tests revealed that less than 20 percent of participants had moderate to severe hearing loss, while nearly half of the group was classified as having mild hearing loss. However, the researchers found that participants who had finished college performed better cognitively over time than those who didn’t.

“This was a somewhat unexpected finding,” said researcher Ali Alattar. “Others have postulated that cognitive deficits related to hearing impairment may arise from social isolation, but in our study, participants who had hearing impairment were as socially engaged as those without hearing loss.”

The researchers hope these findings serve as a warning to healthcare professionals, and they encourage their patients to start protecting their hearing as early as possible.

Other risks

The researchers emphasize in their study that hearing loss cannot be reversed, and as their findings showed, patients can experience more than just impaired hearing.

Another recent study found that hearing loss could be associated with premature death.

The study found that those with spouses or partners were less likely to die early due to hearing loss; however, the researchers found that accidental deaths were a much larger risk for those who were on their own.

“Old age greatly increases the risk for hearing loss,” said Dr. Vegard Skirbekk. “Therefore, as the population ages, we are seeing increasing numbers of people with hearing loss. At the same time, there are greater numbers of adults living without a partner -- putting people with hearing loss at an increased risk for death.”
