Understanding Audiometric Frequency Thresholds
Hearing thresholds measure the softest sound intensity (expressed in decibels of Hearing Level, or dB HL) that an individual can reliably detect at specific frequencies (measured in Hertz, Hz). An audiogram plots these thresholds across the acoustic spectrum to evaluate auditory function.
Key Frequency Bands in Audiometry
- Low Frequencies (250 Hz - 500 Hz): Capture environmental hums, vowel formants, and fundamental voice pitches.
- Mid Frequencies (1,000 Hz - 2,000 Hz): The core speech frequency band critical for understanding conversational language clarity.
- High Frequencies (4,000 Hz - 8,000 Hz): Detect subtle consonant sounds (like 's', 'f', 'th') and are typically the first frequencies affected by noise-induced hearing loss or presbycusis.
