Why train your hearing?
Frequency recognition builds critical listening
Professional mixing engineers, mastering engineers, and acoustic consultants spend years developing their ability to identify frequency ranges by ear. This is not a mystical skill - it is a learned, trainable ability.
When you can immediately recognize that a speaker has a "3kHz peak" or a "dip at 250Hz," you hear your equipment more accurately and choose more wisely.
About the frequency range
Human hearing extends from approximately 20Hz to 20kHz, though this varies significantly with age and hearing health. The tool includes tones above 18kHz so you can check your own hearing ceiling - and discover how it changes over time.
Below 80Hz, you feel the vibration as much as hear it. The 200Hz-5kHz range is where most musical detail lives. Above 12kHz, you're hearing the "air" of cymbals and string instruments.
