As we age, we hear people getting worse. Young people listen to 20 years still good to about 18 kHz. One hears only 90 years to about 5 kHz. A 30-40 year old should be able to hear up to 14.000 Hz. By loud music or noise in the environment, but this threshold is further reduced. Test your hearing and determine so how old are you (or your ear) really are. You can adjust the frequency of 1.000 Hz to 18.000 Hz. The program does not replace a professional hearing test. Use it to determine generally whether you have good hearing. Go to a doctor in case of suspicion and leave it there to carry out a professional hearing test.
