Homework Answers
The hearing range of a normal, healthy human without any prior hearing loss is in the range of :
e. 20-20,000 Hz
The sound below 20 Hz is called infrasound waves. And sound above 20KHz is called ultrasound waves. Many animals (like Dolphins) can hear sounds beyound normal human hearing range.
But this range changes over time either due to some hearing loss pertaining to some injury or ageing. So the range may decrease.
It was a pleasure answering your question. Hope this helps...
Good luck!

A person with normal hearing can hear sound waves that range in frequency from approximately 20 Hz to 20 kHz (1 kHz=1 kilohertz=103 Hz). Assuming the same medium, when compared to a 20 Hz sound wave, a 20 kHz sound wave has A. a shorter wavelength and a faster propagation speed. B. a shorter wavelength and a slower propagation speed. C. none of these. D. longer wavelength and a faster propagation speed. E. a longer wavelength and a slower propagation...

A recent study examined hearing loss data for 1822 U.S. teenagers. In this sample, 343 were found to have some level of hearing loss. News of this study spread quickly, with many news articles blaming the prevalence of hearing loss on the higher use of ear buds by teens. At MSNBC.com (8/17/2010), Carla Johnson summarized the study with the headline: "1 in 5 U.S. teens has hearing loss, study says." To investigate whether this is an appropriate or a misleading...
