In this video, my granddaughter Rina and I are going to offer you a hearing test. Kids can hear higher frequencies while our ability to hear high-pitched sounds wanes as we age. This process is called presbycusis [ˌprez-bi-ˈkyü-səs] and it can be observable in people as young as 18! The older we get the harder it becomes for us to hear high frequencies. You can take a hearing test. Put on your headphones, make sure you are in a quiet place without background noise. We will play a sound with increasing frequency. As soon as you stop hearing the sound, stop the video and read the frequency in kHz. This frequency is your high-frequency hearing threshold.
