# Science with Rina. Human Hearing Range

Video illustration to TranslatorsCafe.com Sound Wavelength Calculator. An average human can hear frequencies from 20 Hz to 20 kHz. 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.

### Science with Rina. Sound Frequency and Wavelength

Video illustration to TranslatorsCafe.com Sound Wavelength Calculator. We’ll play several sounds and show you their frequency and wavelength. 220 Hz or vibrations per second. 440 Hz or vibrations per second. 880 Hz or vibrations per second. The number of these vibrations per second is called the fr
