What is ultrasonic sound?
Ultrasonic sound refers to sound waves with frequencies higher than the upper threshold of human hearing, typically greater than 20 kHz. These sound waves are used in various applications such as medical imaging, cleaning, and distance measuring due to their ability to penetrate materials and produce detailed results.
Why low frequencies are highly attenuated?
Low frequencies are highly attenuated because they have longer wavelengths that interact with obstacles and are scattered, absorbed, or diffracted more easily than higher frequencies. This results in a greater loss of energy as the low-frequency sound wave travels through a medium.
Are sound waves with frequencies higher than 20 000 Hz referred to as subsonic waves?
No, sound waves with frequencies higher than 20,000 Hz are referred to as ultrasonic waves, not subsonic waves. Subsonic waves are sound waves with frequencies lower than 20 Hz.
What is a sound that has a too high frequency called?
the sound that is too high pitch to hear is called an ultrasound.
What different between ultrasonic wave and supersonic wave?
Ultrasonic refers to frequencies greater than those that can be heard (usually frequencies above 20 kHz). Supersonic refers to velocities faster than the speed of sound (in the medium under consideration).

What name is given to frequencies greater than 20 kilohertz?
Ultrasound is sound with a frequeny above the range of human hearing.(Above 20 000Hz)
Which equipment works at frequencies greater than 20000hz?
ultrasonographs

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.
Do all animals hear the same frequencies of sound as humans do?
No, animals do not hear the same frequencies of sound as humans. Different animals have different ranges of hearing, with some able to hear higher or lower frequencies than humans.

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 wave characteristics affects the loudness of a sound?
The amplitude of a sound wave directly affects its loudness – greater amplitude corresponds to louder sounds. The frequency of a sound wave can also affect loudness, as higher frequencies are generally perceived as louder than lower frequencies at the same amplitude.
