Treble Test
Test high-frequency clarity from 8 kHz to 20 kHz. Identify clarity loss or distortion in your audio equipment.
Volume Warning
High frequencies can be piercing. Start with low volume and increase gradually.
Current Frequency
Quick Frequency Test
Frequency Sweep
Presence (8-12kHz)
Adds clarity and definition to vocals and instruments.
Brilliance (12-16kHz)
The 'air' and sparkle in high-quality recordings.
Ultra-High (16-20kHz)
Most adults cannot hear above 16kHz. This range tests equipment limits.
Typical Hearing by Age
- Under 20: Up to 20kHz
- 20-30 years: Up to 18kHz
- 30-40 years: Up to 16kHz
- 40-50 years: Up to 14kHz
- 50+ years: Up to 12kHz
High Frequency Hearing and Audio Quality
Treble frequencies carry the detail and clarity in audio. From the shimmer of cymbals to the sibilance in speech, high frequencies define the character of sound.
Why Treble Matters
High frequencies provide the 'air' and openness in recordings. Without adequate treble response, audio sounds muffled and lacks definition.
Age-Related Hearing Loss
Presbycusis (age-related hearing loss) primarily affects high frequencies first. The hair cells in your inner ear that detect high pitches are the most delicate and degrade over time.
Equipment Limitations
Many Bluetooth codecs and streaming services cut off frequencies above 16kHz to save bandwidth. High-resolution audio formats preserve these frequencies for listeners who can hear them.
