Cuse of the manner in which sound (and, in particular, low frequency sound) is propagated unnder water, whalies, dolphins and the like as well as fieesh will be able to detect them, though it may not be "heering" as we no it.
and eliphants and lions
The skin on the sides of their head and sometimes their forehead will flutter.
Many animals can detect ultrasonic frequencies, including bats, dolphins, and certain species of rodents. Bats use echolocation, emitting ultrasonic sounds to navigate and hunt for prey. Dolphins also utilize echolocation, with their vocalizations reaching ultrasonic levels to communicate and locate objects underwater. Additionally, some dogs and cats can hear ultrasonic sounds, which are inaudible to humans.
Because humans don't have the right body structure or the strength to do so. This also deals with the fact human hearing can't detect sounds below about 20Hz(Hertz)
Humans cannot hear the same sounds as some animals due to differences in the range of hearing frequencies. While humans typically perceive sounds between 20 Hz and 20,000 Hz, many animals, such as dogs and bats, can hear higher frequencies, sometimes exceeding 65,000 Hz. This variation is due to differences in the anatomy of the ear and the sensitivity of auditory systems, which have evolved to meet the specific needs of each species in their environment. Consequently, animals can detect sounds that are inaudible to humans, aiding in communication, navigation, and hunting.
Frogs are just very sensitive to sounds and movement- it is natural for them as they are preyed upon by many species. The ears on the side of their head I believe aids them in sensing movement in their environment.
Subsonic sounds can affect internal organs. Once that is established the mental effects will be clear too.
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.
The skin on the sides of their head and sometimes their forehead will flutter.
Breaking of the sound barrier unless subsonic ammunition is used is one.
Whales navigate with subsonic vibrations. like sonar
Subsonic signals are sounds or vibrations that have a frequency lower than that which may be heard by the human ear as a discernable tone. Vibrations lower than 30 Hz (30 cycles per second) are considered subsonic.
yes dogs can detect lower or higher sounds than humans
The antonym for subsonic is supersonic.
Sonar
Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100 kHz. This called ultrasound.Elephants can hear sounds at 14–16 Hz, while some whales can hear subsonic sounds as low as 7 Hz (in water).
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
