Three factors of sound
Three factors of the sound is in three height, tone, strength, they are
related to the factors of the wave amplitude of frequency, waveform, and
frequency, respectively.First, the height of the sound is determined by
the frequency, but the sound high enough frequency is large, the sound
you hear low frequency is small.I depends on the difference in the waveform
of the sound wave mainly for tone.If you are related to the amplitude with
frequency, and represents the energy about the strength of the sound.For
example, frequency is at the same time, I hear the sound strong enough
amplitude is large.
Reflection of sound・Diffraction
Many of the sound wave that we in the ear, a few cm ~ m number of wavelength
sucks.By diffraction, wave like this is easy to wrap.In addition, sound
waves are reflected.
