Reasons Why 100% Digital Technology With HearPod Is Better For Hearing Aids
Go to: Previous Article Next Article
The first hearing aids were invented in the 15th Century to help people who suffered from hearing loss. They were costly and accessible only to the financially well-to-do or upper classes of society. Those now-archaic-looking instruments were fashioned from wood and resembled the shape and size of a human ear so that they amplified sound naturally.
Every 1 in 6 persons suffers from loss of hearing. Many factors such as trauma, age, work-related injuries, etc., will be the causes of the impairment. Regardless, the resulting symptoms are the same in that hearing and distinguishing sounds become decreased or negligible. Many people need a hearing appliance only to magnify sound while others might need more assistance.
There are three basic parts to a hearing aid: a microphone, a receiver and an amplifier. All hearing aids, until recently, changed incoming sound waves into outgoing electrical signals to amplify sound. Those early styles can significantly frustrate and stress users due to muffled sounds, high-pitched squeaking and feedback noise.
The introduction of digital systems has offered great improvements and advantages to the industry. Incoming sounds are still received through a microphone. A receiver then picks up those sounds and, by way of a computer chip within the device, converts the sound waves into digital (mathematical) codes, not electric ones. The code is converted back to sound again, then amplified in a naturally audible way.
Although digital systems are more expensive than the previous electric signal styles, they are more comfortable, more convenient and provide superior sound quality. Several channels are available to distinguish and amplify the sound source or to reduce ambient noise. Disposable varieties are available from some manufacturers.
Some hearing aids fit snugly behind the ear. Some are fitted directly into the outer ear canal. The plastic housing of the appliance is usually clear or flesh-toned.
A hearing disabled person will want to purchase hearing aids which are comfortable to wear and easily maintained. The most desirable qualities are: restoration of natural hearing, automatic settings adjustment, and elimination of background noise, muffled sounds and high-pitched feedback. To say hearing loss is an inconvenience is to minimize the impact of this impairment: however, today's advanced technology helps suffers cope much more effectively than those who lived in the 15th Century.
