Understanding Human Hearing & Frequency Response
Human Hearing Range
The human auditory system processes frequencies differently across its range:
- Sub-bass (20-60Hz): Felt more than heard, requires powerful systems
- Bass (60-250Hz): Fundamental frequencies, room acoustics critical
- Midrange (250Hz-4kHz): Most sensitive range, speech intelligibility
- Treble (4-20kHz): Clarity and detail, first affected by age/damage
Equal Loudness Curves
Human hearing sensitivity varies by frequency:
- Peak sensitivity: 2-5kHz range (speech frequencies)
- Fletcher-Munson curves: Loudness perception changes with volume
- Masking effects: Loud sounds hide quiet ones nearby in frequency
- Critical bands: Frequency resolution limits of the ear

How Our Professional Frequency Test Works
Advanced Psychoacoustic Testing Engine
Our frequency response test uses calibrated pure tones and adaptive threshold detection to map your hearing across the entire audible spectrum:
1. Calibrated Pure Tones
Generates mathematically pure sine waves at precisely controlled frequencies from 20Hz to 20kHz with <0.01% THD.
2. Adaptive Threshold Detection
Uses modified Bekesy tracking to find your threshold of hearing at each frequency with ±2dB accuracy.
3. Equipment Calibration
Compensates for known headphone/speaker response curves to isolate hearing capabilities from equipment limitations.
4. Statistical Analysis
Compares results to age-matched norms and identifies significant deviations requiring professional evaluation.

Age-Related Hearing Loss Patterns
Presbycusis: Age-Related Hearing Changes
Ages 20-30: Baseline Hearing
- Full frequency range typically 20Hz-20kHz
- Minimal threshold variation across frequencies
- Peak sensitivity around 2-4kHz
- Warning signs: High-frequency loss >15kHz may indicate early damage
Ages 30-40: Early Changes
- Gradual high-frequency rolloff begins above 16kHz
- Threshold increases of 5-10dB in ultrasonic range
- Most speech and music frequencies unaffected
- Red flags: Loss extending below 12kHz warrants investigation
Ages 40-50: Noticeable Decline
- High-frequency limit typically drops to 12-15kHz
- Threshold increases of 15-25dB above 8kHz
- Speech clarity may begin to be affected
- Intervention point: Consider hearing protection strategies
Ages 50+: Significant Changes
- High-frequency limit often <10kHz
- Threshold increases of 30-50dB in upper frequencies
- Speech comprehension notably affected
- Professional care: Regular audiological monitoring recommended
Factors Accelerating Hearing Loss
Environmental
- Noise exposure (concerts, machinery, headphones)
- Ototoxic medications (some antibiotics, diuretics)
- Head trauma or acoustic trauma
- Chronic ear infections
Genetic/Medical
- Family history of hearing loss
- Diabetes and cardiovascular disease
- Autoimmune conditions
- Smoking and alcohol consumption
Equipment Limitations vs Hearing Issues
Common Equipment Limitations
Headphone Frequency Response
Most consumer headphones have significant frequency response variations:
- Bass rolloff below 50Hz (except planar/electrostatic)
- Mid-frequency coloration from housing resonances
- High-frequency peaks and dips above 5kHz
- Dynamic driver limitations above 15kHz
Speaker Limitations
Speakers add room acoustics to inherent limitations:
- Room modes affecting bass response below 200Hz
- First reflection interference patterns
- Speaker positioning effects on imaging
- Crossover network phase issues
Differentiating Equipment vs Hearing
Equipment Issues (Correctable)
- Results improve with different headphones/speakers
- Frequency response matches known equipment curves
- Sharp nulls at specific frequencies
- Asymmetric results between left/right channels
Hearing Issues (Require Professional Evaluation)
- Consistent results across different equipment
- Progressive high-frequency loss pattern
- Notched loss at specific frequencies (noise damage)
- Asymmetric loss between ears
Equipment Compensation Strategies
For Accurate Testing
- Use flat-response headphones (Sennheiser HD650, Beyerdynamic DT880)
- Test in quiet environment with minimal ambient noise
- Ensure proper headphone positioning and seal
- Compare results with known equipment limitations
Professional Alternatives
- Clinical audiometry with calibrated equipment
- Insert earphones for precise sound delivery
- Sound booth testing to eliminate room effects
- Bone conduction testing to bypass outer ear issues
Room Acoustics Impact on Frequency Testing
How Your Environment Affects Results
Room Mode Effects (20-300Hz)
Low frequencies interact strongly with room dimensions:
- Standing waves: Peaks and nulls at specific frequencies
- Room size correlation: Smaller rooms = higher frequency issues
- Position dependency: Results vary significantly with location
- Solution: Use headphones for frequencies below 200Hz
Reflection/Reverberation (300Hz+)
Mid and high frequencies affected by surfaces:
- First reflections: Comb filtering from nearby surfaces
- Reverberation time: Affects perceived frequency balance
- Surface materials: Hard surfaces boost high frequencies
- Solution: Near-field listening reduces room influence
Optimal Testing Environment
Room Characteristics
- Quiet (<30dB ambient noise)
- Irregular dimensions
- Mixed surface materials
- Minimal parallel surfaces
Equipment Setup
