Sense of movement in the RSS System
Effect by the Sound Source Movement -1
The sound reflected from the floor reaches your ears slightly later than the direct sound. The mixed
sound of the direct sound and the slightly delayed reflected sound will have a unique tone. Actually,
the sounds we hear are such sounds. If you try to hear some sound in a room with your head moving
up and down, you can notice the change of the sound. The same effect can be recognized by the
taking off sound of a jet plane. This is called the flanging effect, and it can be created in the RSS
System.
A Doppler effect is created by moving the sound source. For example, imagine that an ambulance
is passing by in front of you. As it comes closer, the siren will sound higher, yet it will suddenly sound
lower when it has gone away. This is called the Doppler effect. The Doppler effect, however, cannot
be noticed clearly when the sound source is moving slowly. The RSS System allows you to add the
Doppler effect according to the movement of the sound source.
