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.
