Ultrasonic sounds are sounds that are above our hearing range.

Sounds that are a frequency that is above the range of hearing.
Examples of sounds that are above 90 decibels are lawnmowers, newspaper printing presses, trains are farm tractors. Prolonged exposure to these sounds can cause hearing loss.
Yes, humans can hear high frequency sounds. The range of frequencies that humans can hear typically falls between 20 Hz to 20,000 Hz. High frequency sounds are generally above 2,000 Hz.
The two kinds of sounds are audible sounds and inaudible sounds. Audible sounds are those within the frequency range that human ears can perceive, typically between 20 Hz and 20 kHz. Inaudible sounds, on the other hand, are outside this range, which includes subsonic sounds (below 20 Hz) and ultrasonic sounds (above 20 kHz), and cannot be heard by humans.
Sounds above 85 decibels can be harmful to your ears, especially with prolonged exposure. Continued exposure to sounds above 85 decibels can result in hearing loss and damage to the delicate structures in the ear. It is important to protect your ears from prolonged exposure to high decibel levels.
Continuous exposure to sounds above 85 decibels can cause hearing damage over time. Sounds at 120 decibels or above, such as a rock concert or a gunshot, can cause immediate hearing damage. It's important to protect your ears from loud noises to prevent permanent hearing loss.
Ultrasonic sounds can potentially hurt dogs, as they have sensitive hearing that can be easily disturbed by high-frequency sounds. It is important to use caution when using devices that emit ultrasonic sounds around dogs.
Technically speaking, D sharp major is: D#, E#, F* (F double Sharp,) G#, A#, B#, C* (C double sharp) D#. ***note: a double sharp (*) means that the note sounds a whole step above the principal note. For example: F*=G.
Sounds above 20,000 Hz are considered ultrasonic and are inaudible to humans. Some animals, like bats and whales, can hear sounds in this frequency range. Ultrasonic sounds are commonly used in technology, such as electronic devices like ultrasonic cleaners.
Ultrasonic sounds are generally considered to be frequencies above 20,000 Hz, which is above the range of human hearing. These frequencies are used in various applications such as medical imaging, cleaning, and pest control.
