Who has minimum frequency?

Explanation. The voice of a man is of lower pitch as compared to the voice of a baby girl, baby boy or a woman. Since frequency of sound is directly proportional to its pitch, man’s voice is of minimum frequency as compared to others.

Is there a limit to sound frequency?

There’s no atom in-between to vibrate the opposite direction. So there’s a maximum frequency, the Debye frequency, for any particular type of sound waves in any direction in a given crystal. So you can’t have sound waves with frequencies greater than about the inverse of that collison time.

What is the lowest frequency that a human ear can hear?

The commonly stated range of human hearing is 20 to 20,000 Hz. 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.

Which of the following voice is likely to have maximum frequency?

Answer: Among the voice of man, cow, bird and dog the voice of bird is shriller than other. Hence, the pitch or frequency of bird voice is more than man, cow and dog.

Which Colour has minimum frequency?

The red color light has the lowest frequency and the longest wavelength of the visible colors of light.

What are sounds below 20 Hz called?

At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication, making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances.

Can we hear 7 Hz?

The span of sound that a person hears is termed frequency range; the unit of measurement, Hertz (hz). Although there is considerable variation between individuals, the hearing range is commonly accepted to be 20 to 20,000 hz. The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz.

Can humans hear 10 Hz?

The threshold of hearing is standardized for frequencies down to 20 Hz, but there is a reasonably good agreement between investigations below this frequency. Pure tones become gradually less continuous, the tonal sensation ceases around 20 Hz, and below 10 Hz it is possible to perceive the single cycles of the sound.

Who has maximum frequency?

Gamma rays have the highest frequency in the electromagnetic spectrum.

Which of the following have maximum frequency?

The correct answer is X-rays.

Which light has maximum frequency?

Violet waves
Violet waves have the highest frequencies.

What is the frequency range of sound that humans cannot detect?

Human ear cannot detect sound frequencies less than 20 vibrations per second i.e. 20 Hz. So any sound below this frequency will be inaudible sound for humans. In the high-frequency range, the human ear cannot detect frequencies above 20000 vibrations per second (20 KHz) and the amplitude of the wave would be depending on the loudness of the sound.

What is the frequency range of audible sound?

The ultrasound equipment used for tracking and studying many medical problems works at frequencies above 20 kHz. The human ear can easily detect frequencies between 20 Hz and 20 kHz. Hence, sound waves with frequency ranging from 20 Hz to 20 kHz is known are audible sound.

What is the range of sound that humans can hear?

The commonly stated range of human hearing is 20 Hz to 20 kHz.[6][7][note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz[8] 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.[9] Humans are most sensitive to (i.e. able to discern at

What is the frequency below 20 Hz called?

So the frequencies below 20 Hz and above 20 kHz comes under the category of inaudible frequencies. The low-frequency sound which the human ear cannot detect is also known as infrasonic sound.
