![]() The term hyperacusis refers to individuals who are highly sensitive to and bothered by certain sounds (usually loud high pitched sounds). ![]() ![]() Infants and small children have tiny ear canals and are therefore typically more bothered by loud high frequency sounds. In general, the smaller the ear canal, the more amplification in the higher frequencies. The exact amount of amplification, the ear canal resonance, is particular to the individual and depends on, for example, the length, volume and curvature of the canal. The ear canal, specifically, amplifies sound in the high frequencies (for an adult, typically in the region between 2000-4000 Hz). The auricle (the outer part of your ear) and the ear canal (the passage down to the eardrum) serve not only to collect and funnel sound, they also serve to amplify sound.
