All motorized vessels must carry a sound-producing device capable of producing a blast that is audible for at least one-half mile. This requirement ensures that vessels can signal their presence and intentions to other boats, especially in conditions of reduced visibility. The specific regulations may vary by jurisdiction, so it's important for vessel operators to be aware of local laws.
The intensity of a sound produced by a point source decreases as the square of the distance from the source. Consider a riveter as a point source of sound and assume that the intensities listed in Table 12.1 are measured at a distance 1 m away from the source. What is the maximum distance at which the riveter is still audible? (Neglect losses due to energy absorption in the air.)
The term radioactivity is further explained by the use of a Geiger counter. This device detects and measures the presence of radioactive particles or radiation by producing audible clicks or visual displays. It is commonly used in various fields like nuclear physics, medicine, and environmental monitoring.
Mice are known for producing high-pitched sounds that are beyond the human hearing range, typically around 20kHz. While women can also produce high-pitched sounds, they are usually within the audible range for humans, typically around 1-4kHz.
Below audible frequencies are sounds that are too low for the human ear to detect. These frequencies are typically below 20 Hz and are often felt as vibrations rather than heard as distinct sounds. Some animals, like elephants and whales, can detect and communicate using infrasound frequencies.
The range of wavelengths of visible light is approximately 380 to 750 nanometers (nm). In comparison, the wavelengths of audible sound typically range from about 1.7 centimeters (17,000 nm) for high frequencies to about 17 meters (17,000,000 nm) for low frequencies. Thus, visible light wavelengths are significantly shorter than those of audible sound, with light being several orders of magnitude smaller.

The alarm bell could be heard audibly in the distance.

Singultus is the state of having the reflex spasms of diaphragm and accompanied by the rapid closure of glottis producing the audible sound.

An audible wave is a sound wave that falls within the range of frequencies that the human ear can detect, typically between 20 Hz and 20,000 Hz. These waves are responsible for producing the sensation of hearing when they interact with the auditory system.
The audible range of sound for an eagle is typically between 1,000 to 6,000 hertz. They have excellent hearing capabilities and can detect sounds over a considerable distance, aiding them in hunting and communication.

I believe it is 219 miles, 352 km by a tornado.
Audible refers to sounds that are able to be heard, eg. "ultrasound is audible to dogs".
Audible Treats was created in 2004.
The range of distance within which sound can be heard is called the audible range. This refers to the distance at which sound waves are able to reach a person's ear and be perceived as sound.
