Not everyone necessarily needs a hearing test, but some people would benefit from it. If you are not sure if you do, you can always ask your doctor, or just get one anyway. There are also some warning signs that you should get one.
One of the signs that you should schedule a hearing test is when your ears hurt for no apparent reason. If you cannot figure out why, you should try to have them looked at by a professional. You may have a simple ear infection, or there may be a larger issue behind the pain. A professional can take a look and find out if the problem has compromised your ability to hear. If not, he or she might be able to diagnose the issue, or at least refer you to a doctor who can treat you. If your ability to hear has in fact been reduced, the professional you see might be able to diagnose the issue and get you the equipment or treatment you need to hear better.
Another sign that you need a hearing test is that you have noticed you cannot hear as well as before. If other people can hear things that you cannot, you need to find out the problem. It can usually be fixed with some treatment, or at least with the proper device for your ears. An exam can let you know how severe the problem is, which can guide the practitioners in getting the treatment you need. This is important since it can be dangerous and uncomfortable to continue on without addressing your decreased ability to hear.
In addition, you should get a hearing test if you have had ear problems in the past. If you are known for medical issues with ears, including partial deafness that seems to have gotten worse, or frequent ear infections, you should get an exam. The same goes if you are older, since you tend to lose your ability to hear easily as you age. You may need either treatment or devices for your ears in order to hear as well as you used to.
After your hearing test, the staff at the clinic you choose will likely tell you your options. You will likely be shown any devices that can help, or given a referral to a doctor who can treat you. No matter what the treatment ends up being, you deserve to get an accurate diagnosis quickly so you can start to hear better soon.
