WebAs we get lower on the spectrum, heading toward 20 Hz, we become less and less sensitive to SPL levels. We actually feel these sub-bass frequencies (20 Hz – 60 Hz) more than we hear them. On the higher end of the spectrum, we slowly lose sensitivity as we get older and repeatedly damage our hearing. WebThe Audible Spectrum. Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as …
