Two is better than one
Two hearing devices are always better than one - not because they make sounds twice as loud. but because they provide a more natural perception of sound.
Imagine listening to your favorite program on the stereo. It has two amplifiers and two speaker to give music and speech a natural depth. If only one amplifier and speaker are working, the sounds become shallow and flat. This is how people who only wear one hearing aid, but should be wearing two, may also perceive sound. And that puts them at a disadvantage. Firstly, their ability to localize sounds is compromised. This is because the brain needs input from both ears to find out where sounds am coming from. Imagine being on a busy street. If a car is approaching from the right and the driver honks his horn, the sound will reach your right ear a fraction of a second before it reaches your left ear. And it will arrive with a certain power and intensity. Your brainimmediately processes this information and tells you exactly what you need to know where the car is coming from and at what distance.

Another area that demands good hearing in both ears is when you are in a noisy environment trying to focus on a conversation. It could be at a party for instance, where everyone is talking and people are constantly moving around. Once again, the brain needs input from both ears in order to separate the uninteresting. background sounds from the more amusing speech sounds in the foreground. With two hearing aids you have a much better chance of hearing and understanding what is being said.

Perhaps one of the most important reasons to wear two hearing aids is that they reduce the risk of a condition known as 'auditorv deprivation', This is when the brain gradually loses some of its ability to process information from the unaided ear because of a continued lack of sound stimulation. A deprived ear will become more and more lazy so it is important not to wait too long.

Two hearing aids can also make sounds more enjoyable and more comfortable to listen to. It becomes less of a strain to hear, and sounds have the kind of clarity and depth that provide a sense of space and volume. In other words, you get more out of the sounds in the world around you.
