| Fletcher-Munson Curve | Our sensitivity to sound depends on its frequency and volume. Human ears are most sensitive to sounds in the midrange. At lower volume levels, humans are less sensitive to sounds away from the midrange, bass and treble sounds "seem" reduced in intensity at lower... Read More |
| Frequency | The range of human hearing is commonly given as 20-20,000Hz (20Hz-20 kHz). One hertz (Hz) represents one cycle per second; 20Hz represents 20 cycles per second and so on. Lower numbers are lower frequencies. |
| Full-Range | A speaker designed to reproduce all or most of the sound spectrum. |
