How This Tool Works
This hearing test uses the Web Audio API to generate pure sine wave tones at different frequencies. You can test frequencies from 20 Hz (very low bass) to 20,000 Hz (very high frequencies) to determine your hearing range. The tool creates audio oscillators that produce clean, pure tones without harmonics or distortion, allowing you to test your ability to detect specific frequencies accurately. The frequency range covers the full spectrum of human hearing, from the deepest bass notes to the highest treble frequencies that most people can perceive.
The tool is completely client-side, meaning all audio generation happens in your browser using JavaScript and the Web Audio API. No data is sent to any server, ensuring complete privacy and fast performance. The audio is generated in real-time as you adjust the frequency slider or use the quick test buttons. This makes it ideal for quick hearing checks, understanding your personal hearing range, and testing audio equipment or headphones. However, remember this is an educational tool - for medical hearing assessment, always consult a qualified audiologist.
Understanding Frequency Ranges
- 20-250 Hz: Low bass frequencies (sub-bass, bass)
- 250-2000 Hz: Mid-range frequencies (vocals, most instruments)
- 2000-8000 Hz: High frequencies (cymbals, high-pitched sounds)
- 8000-20000 Hz: Very high frequencies (often lost with age or noise exposure)
Note: Most adults can hear 20 Hz to 15-17 kHz. The ability to hear high frequencies typically decreases with age and exposure to loud noise.
Safety and Disclaimer
Important: This is an educational tool, not a medical hearing test. Always start with low volume to protect your hearing. If you have concerns about your hearing or notice sudden changes, consult an audiologist or healthcare provider.
Prolonged exposure to loud sounds can cause permanent hearing damage. Use this tool responsibly and at moderate volume levels.
FAQ
- What is a normal hearing range?Human hearing typically ranges from 20 Hz (low bass) to 20,000 Hz (very high frequencies). However, the upper limit decreases with age. Most young adults can hear up to 15-17 kHz, while older adults may only hear up to 8-12 kHz.
- Is this a medical hearing test?No, this is an educational tool for testing frequency detection. It is not a substitute for a professional hearing test conducted by an audiologist. For medical hearing assessment, consult a healthcare professional.
- Why can't I hear some frequencies?Several factors affect frequency detection: age (high-frequency hearing decreases with age), exposure to loud noise, genetics, and individual differences. If you're concerned about your hearing, consult an audiologist.
- Should I use headphones or speakers?Headphones are recommended for best results, as they provide more accurate frequency reproduction and isolate the test tones. Make sure to start with low volume to protect your hearing.
- What if I can't hear frequencies I used to hear?If you notice a significant change in your ability to hear certain frequencies, especially if it's sudden, consult an audiologist or healthcare provider. This could indicate hearing loss or other medical conditions.
