2. The secondary waves, which are reflected from the room’s boundary surfaces.
The reflected sound is delayed according to the distances involved from the speaker to the boundaries, then back to the listener. It is important for the reflected
In every room, there will usually be more than one magic spot for the VRs to sound their best. However, finding those spots is not intuitive, due to the nature of reverberation characteristics and room dimensions, which vary enormously from room to room. The VRs, being Virtual Reality simulators, are designed to load the room very similarly to the way a live instrument would load the room. Only in this way can your ear/brain hearing mechanism be lulled into believing that you could be listening to an actual performance, and not simply ‘canned’ sound. If you had a grand piano at the end of the room where the speakers are playing, it would involve the entire room with semi- omnidirectional sound, and your ear/brain hearing mechanism will clearly know this. The VR Virtual Reality design will simulate this huge soundfield, with its involving depth and dimension. However, correct placement is required to achieve the best possible sound quality. Amazingly, moving the speaker only a few inches can make the difference between good sound and great sound due to the reflective properties of your room! Note that this fact is true with any speaker system.
PINK NOISE TEST TO FIND FOCAL POINT OF ARRAY: Since the
PINK NOISE LISTENING TEST FOR FOCUS: Play a pink noise source such as a CD with test tones or an FM tuner set between stations (with muting turned off). You will notice one of two sonic effects when listening to pink noise:
1.If you are in the focal point of the array, you will hear a “ball” of noise that appears to float between the speakers. Although noise will appear to emanate from the speakers themselves, the center image will be stronger, with a slightly different tone quality to the phantom center image. The sound from the speakers themselves will seem slightly detached from the pink noise ball, and slightly softer in volume level. The center “ball” of sound will be very strong, and you will be able to detect that the “ball” of sound is round, with depth to the image. This is a ‘locked in’ image with correct focus.
