Question 1

How accurate is an online hearing test?

Accepted Answer

Online hearing tests give a general indication of your hearing frequency range but are not a medical diagnosis. Results vary based on your headphones, ambient noise, and browser audio implementation. For clinical accuracy, consult an audiologist.

Question 2

What frequency can a normal human hear?

Accepted Answer

The human hearing range is typically 20 Hz to 20,000 Hz (20 kHz). However, this range narrows with age. Most adults over 25 cannot hear above 15-16 kHz, and by age 50 the upper limit often drops to 12 kHz or lower.

Question 3

What is the mosquito tone (17kHz)?

Accepted Answer

The 17 kHz mosquito tone is a high-frequency sound that most people under 25 can hear but most adults cannot. It is sometimes used in youth deterrent devices. If you can hear it, your high-frequency hearing is excellent.

Question 4

Why can't I hear high frequencies anymore?

Accepted Answer

Losing high-frequency hearing is a natural part of aging called presbycusis. Loud noise exposure, genetics, and certain medications can accelerate it. Protect your hearing by limiting loud volume and wearing ear protection in noisy environments.
