This app is a useful tool for the elderly or those who are regularly exposed to loud sounds. The test can help you determine the maximum frequency you can hear and evaluate your hearing age. 

Hearing is one of our most important senses. We can hear various sounds such as speech, animals, and nature. Unfortunately, as we get older, our hearing abilities gradually decline. 

This is because the ear has a limited capacity for the absorption of sounds. When we are old, our ears are less effective at transmitting sound to the brain. This makes us more susceptible to hearing loss.
