1.5k hz is a frequency measured in Hertz (hz). 1.5k means the wave cycle is completed 1,500 times per second (not terribly high). The average teenager can hear from 20 hz to 13k-14k hz if that gives you any perspective.
they are sound waves with frequencies ranging from 20 to 20,000 Hz
Hertz (Hz)
20 hz to 20,000 Hz
"can't be heard by humans."
Number of waves in a time is "Frequency" Normally "Waves per Second" which is called "Hertz" - Hz
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
they are sound waves with frequencies ranging from 20 to 20,000 Hz
Hertz (Hz)
Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics
20 hz to 20,000 Hz
sound waves, between about 20 Hz to 20000 Hz (for most people).
No, you can measure anything with a cyclic behavior with hz. eg light waves, radio waves, oceanic waves, car engines, meeting schedules, orbital frequencies.
In a cave at a frequency of 42,000 Hz
"can't be heard by humans."
Number of waves in a time is "Frequency" Normally "Waves per Second" which is called "Hertz" - Hz
No. Such sounds are suprsonic sounds.
The definition of infrasonic is relating to sound waves with a frequency below the limit of human hearing, 20 Hz. Ultrasonic relates to sound waves with a frequency above the limit of human hearing, 20,000 Hz.
