What is a reflection free zone?
A reflection-free zone (RFZ) is simply a region surrounding your listening position where you don’t hear initial reflections. Splay (angle) your walls and ceiling so early reflections are deflected away from your listening position. This type of geometry is common in professional studio control rooms.
Should you put acoustic treatment behind speakers?
In general you should avoid having your speakers anywhere from 12” to 30” from the front wall, unless you treat directly behind the speakers. Otherwise you can get cancellations and peaks in response due to reflections from the front wall.
Why are acoustics bad windows?
They are also a noise or barrier issue. They lack the density of the walls they are supported by and noise finds the weakest link in any wall design. Do not be tricked by terms such as acoustic windows. So, that said, windows and glass are the worst sound you could ever imagine to bounce any sound energy of (them).
What is an early reflection?
Early reflections are the echoes of a signal that arrive at the microphone within a stretch of about 30ms after the direct sound. Early reflections are direct copies of the direct sound source, rather than diffuse mixtures as are present in the late reflections, or reverberation, or a sound source.
What is a first reflection point?
The first reflection point is the mirror point between the monitor or loudspeaker and the listening position. These are on the two walls either side of the mixing or control desk. The third reflection point is found on the ceiling between the monitors and the listening position.
How do you reduce reflection in a room?
Diffusion takes the reflection and reduces its signature by breaking it up into little reflections, if you will. These smaller energy signals are not affected in time or amplitude. Absorption is the recommended treatment for side walls and diffusion works well on front and rear walls.
What is primary and secondary reflection?
Primary reflection examines its object by abstraction, by analytically breaking it down into its constituent parts. It is concerned with definitions, essences and technical solutions to problems. In contrast, secondary reflection is synthetic; it unifies rather than divides.
What do early reflections sound like?
Classifying Reflections The early reflected sound leaves the loudspeaker and then bounces off one of the boundaries of the room* before reaching the ears of the listener. * these are: ceiling, floor, front wall behind speakers, rear wall behind listeners, left side wall, right side wall.
What is sound reflection?
If a sound is not absorbed or transmitted when it strikes a surface, it will be reflected. Reflection of a sound wave at a barrier, as if from an imaginary source at an equal distance behind the barrier. Sound reflection gives rise to DIFFUSION, REVERBERATION and ECHO.
Why do you put acoustic panels behind speakers?
So putting sound absorption technology between the speakers and the front wall is a great idea. This area is very critical for low-frequency absorption. Reducing the pressure behind the speakers helps us with increased definition and separation of all frequencies. Front wall frequency issues usually start at 30 Hz.
Should I put acoustic foam behind my monitors?
Acoustic foam is a common choice of absorber in this application. Clearly, we can also hear sounds from behind us, so the rear wall will also be a source of reflections, plus there will be reflections from the wall directly behind the speakers, and all these need to be considered when applying acoustic treatment.
