Audible Range of Humans
Loudness falls within the typical audible range of 0 to 180 dB, however, anything louder than 85 dB can be harmful. Animals and people both hear by detecting airborne vibrations brought on by sound waves. Ultrasounds are noises with a frequency below infrasound, which are sounds with a frequency higher than the maximum limit of human hearing. Below, we have discussed types of Sound.
Sound frequencies below 20 Hz, or 20 vibrations per second, are inaudible to the human ear. As a result, no sound will be perceptible to humans below this frequency. Since the human ear cannot detect frequencies higher than 20,000 vibrations per second (20 kHz), the wave's amplitude would depend on how loud the sound was. As a result, the inaudible frequency range lies between 20 Hz and 20 kHz.
To the human ear, frequencies between 20 Hz and 20 kHz are easily heard. As a result, sound waves with a frequency between 20 Hz and 20 kHz are considered to be an audible sound. Every little change in air pressure may be heard by a person if it is within audible frequency range. One billionth of a change in air pressure can be noticed.
What is the audible range (hearing range) of humans? (A) 20 Hz - 20000 Hz (B) 80 Hz -100 Hz (C) 2 lac Hz - 4 lac Hz (D) 0 Hz - 20 Hz
The audible range of humans is 20 Hz to 20000 Hz (people have a hearing range between 20 Hz and 20000 Hz.) After this range, humans can not hear the sound. However, bats can hear at a higher frequency of Sound.
