Sounds with frequencies below 20 Hz are called infrasound, and those above 20,000 Hz are called ultrasound; neither is audible to humans under normal conditions. While the sensitivity varies significantly with age (higher frequencies are often less audible as people get older), the range 20-20,000 Hz represents the general limits of human hearing.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nThe human ear is most sensitive to frequencies between 1,000 Hz and 4,000 Hz. The ability to hear high frequencies tends to decrease with age, a phenomenon known as presbycusis. Other animals have different hearing ranges; for example, dogs can hear much higher frequencies than humans (up to 45,000-65,000 Hz).<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which one of the following frequency ranges is sensitive to human ears ?
