Do you hear sounds around you as one frequency at a time or as many frequencies at once?

The commonly stated range of human hearing is 20 Hz to 20 kHz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

hope it help

mark me as brainliest

20 Hz to 20 kHz. Humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz.

Explanation:

learned this in physics about 2 years ago and its stuck with me ever since lol. sorry i am not the best at explaining lol

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
