Mosquito Tone Test
Can you hear the 17.4kHz frequency? Test your hearing age with our high-frequency mosquito tone audibility test.
Important Warning
Always start with low volume! High frequency sounds can be uncomfortable and potentially harmful at loud volumes. Gradually increase volume until you can hear the tone, or determine you cannot hear it.

The Science Behind the Mosquito Tone
What is Presbycusis?
Presbycusis is the gradual hearing loss that occurs as we age. It primarily affects our ability to hear high frequencies, starting from around age 18-20. The 17.4kHz mosquito tone exploits this natural phenomenon.
Why 17.4kHz?
This specific frequency was chosen because:
- Most teenagers and young adults can hear it clearly
- Most adults over 25 cannot hear it at all
- It's high enough to be uncomfortable when audible
- It's within the range affected by early hearing loss
Real-World Applications
Youth Deterrent Devices
Shopping centers and public spaces use mosquito tone devices to discourage loitering by young people without affecting adults.
Secret Ringtones
Students use mosquito tone ringtones that teachers cannot hear, allowing phones to ring undetected in classrooms.
Hearing Health Screening
Quick test to assess high-frequency hearing loss and monitor hearing health over time.
Understanding Your Results
If You Can Hear It
Congratulations! Your high-frequency hearing is excellent. This suggests you have young ears or well-preserved hearing ability.
If It's Faint
You might hear it very quietly or intermittently. This is common for adults in their 20s-40s and indicates some high-frequency hearing loss.
If You Can't Hear It
This is completely normal for most adults over 25. Age-related hearing loss typically starts with high frequencies like this one.
Important Notes
- Equipment Matters: Your speakers or headphones must be capable of reproducing 17.4kHz
- Volume Levels: The test should be done at safe volume levels
- Not Diagnostic: This is a fun test, not a medical hearing assessment
- Individual Variation: Some older adults can still hear high frequencies
- Hearing Protection: Exposure to loud sounds can accelerate hearing loss
