More than half of high school students and over a third of adults reported at least one symptom of hearing loss, possibly due to the increased use of portable music players, earbud headphones, and other consumer technologies, a hearing association announced Tuesday.
In the survey done for the American Speech-Language-Hearing-Association (ASHA), 51 percent of high school-aged children and 37 percent of adults admit to turning up the volume on radio or TV, saying "huh?" or "what?" during normal conversation, or experiencing a ringing in the ears.
Although the survey didn't correlate causes of the hearing loss symptoms, it did find habits potentially dangerous to hearing health. For instance, two-fifths of students and adults set the volume of their iPods to high, fewer than 30 percent use headphones other than the earbud-style models included with portable music players, and large numbers listen for 1-4 hours daily.
"Louder and longer is definitely not the way to use these products," said Brenda Lonbury-Martin, ASHA's head of science and research, in a statement. "Eventually, that becomes a recipe for noise-induced hearing loss, which is permanent."
The issue of potential hearing problems stemming from iPods and other MP3 players, and the use of in-ear headphones, has been simmering for weeks. Last month, a Louisiana man filed a class-action lawsuit against Apple Computer, claiming that the iPod and its earbud headphones can cause hearing damage.
Network slicing could be the answer to 5G rollout – but it's not easy to implement. Automation provides a way forward.
Wi-Fi 7 products, due out in 2024, will offer significantly more performance for enterprise users and can support more users in denser environments compared to Wi-Fi 6.
6G will leverage many different bands and tools to meet the ever-growing demands and expectations for cellular communications.
