Why we hear some frequencies better than others
Posted by Jennifer Spiller on May 28, 2020
If a canary and a crow are standing side by side, chirping and squawking at exactly the same volume, humans will hear the crow but not the canary. This is due to a phenomenon called the upward spread of masking. Low frequency sounds (such as thunder or diesel engines) will make it more difficult to hear high-pitched sounds (such as chimes). Many sounds we deem annoying, like background d noise, are often in the lower frequency ranges. They make it more difficult for us to understand speech, especially sounds like “PH”, “S”, or “CH”, which are very quiet. Age-related hearing loss tends to affect the high frequencies first, which makes low-pitched background noise especially problematic. Appropriately-fitted amplification devices for people with hearing loss can help.
