Basically, a sound wave is louder if it has a greater amplitude.
I would say no. Since humans can't pick up direction we would note, we really only pick up pitch and loudness. Although how close the sound is may change that, but the sound could 'blend' so we can't tell the difference and think it is in face one sound, but then the blend would increase volume.
Silence is a lack of noise there would be no sound.
The softest audible sound is typically around 0 decibels. To find the loudness of a sound that is 26 million times as loud, you would need to calculate the log base 10 of 26 million (7.41), since decibels are logarithmic. Therefore, a sound 26 million times as loud as the softest audible sound would be around 7.41 decibels.
A sound with a frequency of 12000 Hz would be high-pitched rather than loud or soft. Loudness is determined by the amplitude (intensity) of the sound wave, not its frequency.
Sounds are vibrations that spread equally in all directions unless they are directed. Because they can distort or even cancel other vibrations, it is possible to have a point in a noisy room where no sound at all would be heard. A whip makes a cracking sound because its tip moves faster than the speed of sound. It creates a small "sonic boom" as it moves, forcing air out of its way. Sound travels faster in liquids and solids than in air. So if a very long metal rod was struck on one end, someone at the other end would feel the vibration before he heard the sound.

Sound intensity is objective, because it's just a measure of the sound power per unit area. Loudness is subjective, because it has to take into account the sensitivity of the ear and its different responses to different frequencies in the sound. A sound with a frequency of 45 kHz would have no "loudness", since our ears don't respond to that frequency at all. But it would still have intensity, because the sound is still carrying energy.
i would say decibels but this is a guess its what sound is measured in
Silence is a lack of noise there would be no sound.
usually the pitch of the sound the frequency of the sound affect the loudness but as we say loud we mean how high the sound. In other terms when somebody shouts and we get irritated we would say "Not so loud" that means we refer to the person who is speaking loudly. this is known as the factors that affect sound
Exceeding the sound barrier refers to speed of travel, not loudness of sound. A speaker cannot "exceed the sound barrier".
The softest audible sound is typically around 0 decibels. To find the loudness of a sound that is 26 million times as loud, you would need to calculate the log base 10 of 26 million (7.41), since decibels are logarithmic. Therefore, a sound 26 million times as loud as the softest audible sound would be around 7.41 decibels.
Loudness is the quality of a sound that is primarily a psychological correlate of physical strength or amplitude. You can try to measure the sound pressure in decibels. Scroll down to related links and look at "Loudness in sones - Wikipedia ", Loudness level in phon - Wikipedia ", and Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage).
Decibels measure the intensity of sound, not the frequency. The perceived loudness of a sound at 500 Hz would depend on factors like the amplitude or intensity of the sound.
A sound with a frequency of 12000 Hz would be high-pitched rather than loud or soft. Loudness is determined by the amplitude (intensity) of the sound wave, not its frequency.

Loudness is a person's perception of the intensity of a sound wave. A sound wave can be generated by any object able to impart energy to the environment, such as a set of speakers, clapping hands or a laser pulse through the air. Decreasing loudness can be done by removing energy from the sound wave. Generally this is done by adding a dampening material (like foam) in between you and the source of the sound. However, one can also remove the medium over which sound travels (i.e. remove the air and create a vacuum). An extremely loud and powerful sound source on earth would be inaudible on the moon
