Symptoms of Hearing Loss and Levels of Hearing Loss Listen up! Don't take your ears for granted. Hearing loss is the third most common health problem in the U.S, and it can affect the quality of your life and relationships. About 48 million Americans have lost some hearing. Certain conditions, including age, illness, and genetics, may play a role in hearing loss. Modern life has added a host of ear-damaging elements to the list, including some medications and plenty of sources of loud, ongoing noise.
What are hearing aids? In its most basic form, a hearing aid is a device that amplifies the frequencies that you have trouble hearing. Most devices nowadays are digital, consisting of a microphone, digital signal processors, amplifiers, and speakers. Hearing technology has undergone a radical rate of evolution in recent years. The introduction of digital signal processing technology has allowed chips to process multiple millions of calculations per second, resulting in unparalleled sound quality. The durability has improved dramatically, and comfort, as well as aesthetics, have been thoroughly addressed. Modern devices have shrunk so much in size that they are barely noticeable.
