Frequencies over 20,000 Hz are referred to as ultrasonic frequencies. These sounds are typically beyond the range of human hearing, which generally tops out at around 20,000 Hz. Ultrasonic waves are commonly used in various applications, including medical imaging (ultrasound) and industrial cleaning.
What else can I help you with?
What wave can be detected by the ear?
sound waves, between about 20 Hz to 20000 Hz (for most people).
What are waves with frequencies over 20000 Hz?
Waves with frequencies over 20,000 Hz are considered ultrasonic waves. They are higher in frequency than what humans can hear, and are commonly used in medical imaging, cleaning processes, and communication technologies.
What frequencies of sound can humans hear?
typically 20-20000 Hz - but this range will decrease with age
What is the frequency of a sound wave?
The frequencies (cycles per second) of the audible vibrations are between 20 Hz and 20000 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.
What is a sound with frequency greater than 20000 hz?
the sound would be called "ultrasound"
What sound frequencies can humans hear?
typically 20-20000 Hz - but this range will decrease with age
How many harmonics are possible in the normal hearing range 20 Hz 20000 Hz?
It depends on the fundamental frequency. If for example you wanted to find how many harmonics a 20 Hz sound has then its all the integer multiples of that frequency which are still within hearing range, i.e 20000 Hz. For 20 Hz this is 20000/20 = 1000 harmonics.
What frequency of a wave 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.
Sound waves with frequencies higher than 20000 Hz are referred to as subsonic waves?
for this answer it's false i made a 90 on this test :)
What frequency of sounds can people hear?
The range of frequencies that people can hear is generally from 20 Hz to 20,000 Hz. However, individual hearing abilities can vary slightly, with younger individuals typically being able to hear higher frequencies than older individuals.
Using Nyquists theorem calculate the channel capacity C of a signal that has 16 differeret levels and a frequency of 20000 Hz?
Nyquist has shown that C=2 B log2 (M) [bps] C: Capacity B: Bandwidth M: Signaling Levels log2 (x)= [ log10 (x) / log10 (2) ] So We assume F1=0Hz F2=20kHz so B= F2-F1=20000 Hz C = 2*20000* log2 (16) = 2*20000* log10 (16) / log10 (2) = 160 000 bps
