A hearing aid is a small electronic gadget worn behind or in the ear. The device increases the volume or pitch of sounds so that you can hear better and communicate normally. The hearing aid consists of a microphone, speaker and amplifier. The device receives sound from the microphone and converts sound waves to electrical signals before sending them to the amplifier. The amplifier increases the signal strength before sending the sound to the ear through the speaker. Here is some basic information about hearing aid devices:
How Can One Determine Whether They Need Hearing Aids?
If you find yourself straining to hear what people are saying or asking people to repeat their statements, have difficulty comprehending conversations, and prefer the radio or television louder than normal, you need to be checked. The only way you can determine whether you need hearing aids is to schedule an appointment for a hearing test. The test will check the degree of hearing loss to establish whether you need hearing aids or some other form of treatment.
What Are The Different Types of Hearing Aids?
Behind the Ear (BTE) aids
These are the largest devices of their kind, with components positioned behind your ear and connected to a plastic tube. These aids provide more power than other hearing aids. They are also less susceptible to wax damage and moisture.
In the Ear (ITE) aids
These devices are custom-made to fit the design and comfort of the patient. These aids fill the whole inner ear. These are considered the largest custom-made hearing aids. ITEs offer the advantage of volume controls on the device and more power.
In the Canal (ITC) and Completely in the Canal (CIC) aids
ITCs are smaller compared to ITEs; they barely fill half of your ear. Because of their small size, they require more caution when operating them and come with fewer controls. CICs are the smallest hearing aids. They are inserted deep in the canal, which means they are hardly damaged by moisture in the ear canal or ear wax. These devices are difficult to insert and remove and usually do not come with manual controls.
Summing It Up
It is hard to determine whether you need hearing aids without going to the doctor for a hearing test. If you are experiencing some funny sensations or your hearing is problematic, consider scheduling appointment to identify the problem. In many cases, if you cannot properly hear what is being said, then you need to get hearing aids.
