Sound is a longitudinal pressure wave of audible sound. It is a series of sound pressure waves that moves through air or other materials. These sound waves are created by the vibration of some object.
That would be the hearing sensitivity of the person trying to hear the sound.
If a reflected sound wave reaches the ear within 0.1 seconds of the initial sound, then it seems to the person that the sound is prolonged. The reception of multiple reflections off of walls and ceilings within 0.1 seconds of each other causes reverberations - the prolonging of a sound.
All matter (objects) produce sound when they vibrate with the frequency of audible range.Human ears can hear the sound with frequency range of 20 Hz to 20 kHz (20000 Hertz).So if any object vibrates within the audible range it will produce audible sound. Frequency also denotes the pitch of the sound.If the matter or object vibrates in vacuum, then the sound waves is not heard as it needs a medium for propagation of the waves.The loudness of the sound depends on the Energy in the waves.
Within range which sound may be heard.
Almost there
No. The I has a short i sound as in disk. The A has a schwa sound and the E is not heard (there is an ending unssound as in dunce).

Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
Electromagnet radiation must be converted to mechanical movement within the range of audio (20-20khz) to be heard.

yes krakatoa is the loudest sound ever recorded at a distance of 160 kilometres 180 decibels at a distance within 12 kilometres 210 decibels and in range has 270 decibels and within crater 300 decibels the explosion of 200 megatons of TNT has over 363 decibels +++ I cannot vouch for the numbers but they would be peak over-pressures because the maximum airborne sound pressure level possible is 194dB re 20µPa. Even if you use 1µPa as the reference pressure you would add only another 26db, making it 220dB re1µPa.
Not enough information. At what distance from the coconut is the observer of the sound.
If the high frequency sound is within hearing range, you can hear it as a high-pitched sound. If it's out of the hearing range you can't hear it, of course.
That would be the hearing sensitivity of the person trying to hear the sound.
