The Rinne test (Figure 5) will demonstrate air conduction better than bone conduction if the loss is sensorineural. 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/. Although people have different reactions to hearing loss, for many it can. 500 Hz provides information for manner of production, first formant for most vowels, noise bursts for plosives, and information for semi-vowels and laterals /l/ and /r/. Therefore, four hours of noise exposure at 88 dB(A) is considered to provide the same noise dose as eight hours at 85 dB(A), and a single gunshot, which is approximately 140 to 170 dB(A), has the same sound energy as 40 hours of 90-dB(A) noise.8, Noise-induced hearing loss is the second most common sensorineural hearing loss, after age-related hearing loss (presbycusis). Standardized questionnaires for hearing handicap are available (Figure 3).18,19 Some patients may be reluctant to admit hearing loss, and family members may be the first to report a problem. Low Frequency Sound vs Mid Range and High Frequencies. (See degrees of hearing loss to learn hearing loss severity is measured.) Typically, high frequency sounds are the first to get missed when someone has hearing loss. If the loss appears to be sensorineural, etiologies other than noise should be excluded. Since frequency is measuring sound in cycles per second, the lower the frequency value, the slower its cycling speed. Mechanical waves are classified into three groups, depending on the direction of the periodic motion relative to the movement of the wave: Longitudinal waves: Each particle moves back and forth in the same direction as the wave. (2019). A patient whose screening shows evidence of hearing loss should be referred for a full audiologic evaluation.
