The loudness of a sound is related to how much energy is transmitted to the air. Clapping your hands transmits a small amount of energy. Detonating a stick of dynamite transmits MUCH more energy. The amplitude of the sound wave is much greater, and the noise, louder.
You are probably nearer to the point of the thunder.
There is more vibration coming from the object making sound.
because some are higher than others
Contraction is the reason that railway tracks sound louder in winter.
Are there some situations in which such regulations would be more appropriate than others?
Some mixtures are easier to seperate than others because some mixtures are heterozygous mixtures. These mixtures are easier to seperate then others because you can see what is in them so you would know how to get them out.
dogs howl, pigs squeal louder than usual, the main answer is that THEY ACT WEIRD.
Some people get more dust and dirt in their noses and it makes them sneeze louder.
It can be either. Some gongs are much louder than others. Sirens vary in design. However, most of the sirens used today would be louder than any gong you are likely to encounter.
Because sounds louder than that (and actually somewhat softer) cause permanent hearing loss.
anything as loud or louder than a little girl screaming
because the pitch is higher
Parakeets imitate sounds around them. Some take longer than others to pickup regular sounds whist others dont
Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. As sound waves travel farther from their source, the more spread out their energy becomes.
accent
it has to do with distance temp. and wave lengths
som strings are thinner and some are fat
watt is a unit of measure. Units of measure don't make sounds.
Thunder is not louder to dogs than it is to humans, but thunder is more frightening to dogs than it is to humans, because we humans know what thunder is, and dogs don't. To a dog, thunder sounds like the barking of some ridiculously large animal, which would of course be extremely dangerous, if it actually existed.
