Low frequency sounds are detected in the ear by the hair cells located in the cochlea, specifically in the apex or helicotrema region. These hair cells are responsible for converting sound vibrations into electrical signals that are then transmitted to the brain via the auditory nerve.
What else can I help you with?
What is the minimum frequency the human ear can hear?
The human ear can generally detect sounds with frequencies as low as 20 Hz. Below this frequency, the sound may be felt rather than heard.
The lowest frequency a human can hear is?
The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.
Does a low pitched note have a high frequency?
No, a low pitched note has a low frequency. The pitch of a sound is determined by its frequency, with low frequency sounds corresponding to low pitched notes and high frequency sounds corresponding to high pitched notes.
What are some examples of high frequency and low frequency sounds?
High frequency sounds include a whistle, a bird chirping, or a ringing phone. Low frequency sounds include thunder, a bass guitar, or a large drum.
Human ear sensitivity in low frequency range?
The human ear is less sensitive to low frequencies compared to mid-range frequencies. Below 100 Hz, the ear requires higher sound pressure levels to be perceived as equally loud as sounds in the mid-frequency range. This is because the ear is designed to be most sensitive to frequencies between 2,000 and 5,000 Hz, which is where human speech falls.
What is the minimum frequency the human ear can hear?
The human ear can generally detect sounds with frequencies as low as 20 Hz. Below this frequency, the sound may be felt rather than heard.
The lowest frequency a human can hear is?
The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.
What frequency of waves in the air can be heard as an audible sound by the human ear?
For the human ear, sound is audible in the range of 20 Hz (Hertz) to 20000 Hz. Sounds below 20 Hz are "infrasonic" and have too low a frequency to be heard; sounds above 20000 Hz are "ultrasonic" and are too high a frequency to be heard.
Does a low pitched note have a high frequency?
No, a low pitched note has a low frequency. The pitch of a sound is determined by its frequency, with low frequency sounds corresponding to low pitched notes and high frequency sounds corresponding to high pitched notes.
What are some examples of high frequency and low frequency sounds?
High frequency sounds include a whistle, a bird chirping, or a ringing phone. Low frequency sounds include thunder, a bass guitar, or a large drum.
Do low frequency sounds have a high pitch or a low pitch?
Low frequency = low pitch = long waves
What is the lowest frequency that humans can hear?
It varies with individuals of course, but 19-21 is very common
Human ear sensitivity in low frequency range?

What sort of frequency do high-pitched sounds have?
High-pitched sounds have a higher frequency compared to low-pitched sounds.
Are all low sounds quiet?
No, not all low sounds are quiet. The loudness of a sound is determined by its amplitude, not its frequency. Low-frequency sounds can be very loud, as seen in bass music or thunder, while high-frequency sounds can also be quiet. Thus, loudness and pitch are independent characteristics of sound.
How do the inner ear and the brain distinguish the high sound and low sound?
The inner ear contains the cochlea, which is a spiral-shaped structure filled with fluid and lined with sensory hair cells. When sound waves enter the cochlea, high-frequency sounds stimulate hair cells located at the base, while low-frequency sounds activate hair cells further along the cochlea. This tonotopic organization allows the brain to interpret different frequencies based on which hair cells are activated. The auditory nerve then transmits this frequency information to the brain for processing, enabling the distinction between high and low sounds.
How many hertz are in low frequency sound?
Low frequency sounds typically range from 20 to 250 Hz.
