If a person has high-frequencyhearing loss, your audiogram will showa slope to the right, indicating a person has trouble hearing frequencies between 2,000 and 8,000 Hz. 1000 Hz provides additional cues of manner, nasal consonants, back and central vowels, noise bursts of most plosives and semi-vowels. 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/. This case shows that noise-induced hearing loss can interfere with speech discrimination and social functioning. These structures convert sound vibrations into neural impulses. The lower human threshold of hearing, and the lowest pedal notes of a pipe organ. Hi! Frequencies below 20Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. Most everyday sounds we hear fall within 250 to 6,000 Hz, though the full range of sounds a person with normal hearing can detect ranges from 20 to 20,000 Hz.
