Frequently Asked Questions
Quick answers about controls, features, accuracy, and local browser saving.
What is the normal range of human hearing?
A healthy young human ear can detect frequencies ranging from 20 Hz (deep sub-bass) up to 20,000 Hz (ultrasonic treble). As humans age, exposure to loud environments naturally degrades the microscopic hair cells in the cochlea, lowering the upper limit (presbycusis).
How does age correlate with high-frequency hearing loss?
Typical high-frequency cutoff by age:
• Under 24: up to 17,500 – 19,000 Hz
• Under 35: up to 15,000 – 16,000 Hz
• Under 45: up to 14,000 Hz
• Age 50+: around 12,000 Hz and below.
• Under 24: up to 17,500 – 19,000 Hz
• Under 35: up to 15,000 – 16,000 Hz
• Under 45: up to 14,000 Hz
• Age 50+: around 12,000 Hz and below.
Why can't I hear very high frequencies even if I am young?
Many standard laptop speakers and inexpensive earbuds cannot physically reproduce sound above 16,000 Hz due to hardware frequency response limits. For accurate testing, use high-fidelity over-ear headphones in a quiet room.
Is it safe to test at high volumes?
Always keep your volume at a low to moderate level. High frequencies at elevated volumes can cause acoustic trauma or temporary tinnitus.
