What else can I help you with?
Why cant you hear ultra sonic sound?
Humans cannot hear ultrasonic sound because our ears are not sensitive enough to detect frequencies above 20,000 Hz, which is the upper limit of human hearing. Ultrasonic sound waves have a frequency higher than 20,000 Hz, making them outside our audible range.
Who will hear the sound of an approaching boat first this diver or his friend above the water?
The friend above the water will hear the sound of an approaching boat first because sound travels faster through water than through air.
What is a sound that has a too high frequency called?
the sound that is too high pitch to hear is called an ultrasound.
The highest frequency sound human ears can usually hear is about?
The average human can hear frequencies of up to 20,000 Hertz.
What is the softest sound you can hear?
The softest sound a human can hear is around 0 decibels, which is considered the threshold of hearing. This level of sound is almost imperceptible and may be close to complete silence.
What are sound waves with frequencies above the normal human range of hearing?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
Sound waves with frequencies above the normal human range of hearing are called what?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
What is the loudest sound a human can hear?
20,000 Hz (20kHz) is the (ideal) highest FREQUENCY that a healthy human ear can hear. With regard to loud sounds, a sound LEVEL of 120 decibel (dB) causes pain, and a level of 140 dB causes deafness.
Why cant you hear ultra sonic sound?
Humans cannot hear ultrasonic sound because our ears are not sensitive enough to detect frequencies above 20,000 Hz, which is the upper limit of human hearing. Ultrasonic sound waves have a frequency higher than 20,000 Hz, making them outside our audible range.
What is the given name to a sound which is to high for a human to hear?

The quietest sound a human can hear is?
Cells inside your body
Who will hear the sound of an approaching boat first this diver or his friend above the water?
The friend above the water will hear the sound of an approaching boat first because sound travels faster through water than through air.
What is audio sound?
Audio sound is sound which human beings can hear. That is 20 Hz to 20,000 Hz for HiFi.
How ultrasound and infrasound differ from normal sound?
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
What name is given to the sounds which a cat can hear but a human cannot?
Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
What is a sound that has a too high frequency called?
the sound that is too high pitch to hear is called an ultrasound.
The highest frequency sound human ears can usually hear is about?
The average human can hear frequencies of up to 20,000 Hertz.
