Your cochlea contains hair cells with tiny hair-like projections called stereocilia. Since frequency is measuring sound in cycles per second, the lower the frequency value, the slower its cycling speed. Millions of Americans have hearing damage due to noise-induced hearing loss. 2000 Hz provides cues for place of consonant and additional information about manner, front vowels, noise bursts of most plosives and affricates and turbulent noises of fricatives /sh/, /f/, and /th/. Patients with sudden sensorineural hearing loss (hearing loss developing in minutes or hours) should be referred immediately, because treatment initiated within the first 24 hours can improve outcomes.23.
