Are early reflections bad?

Early reflections cause comb filtering Left untreated, early reflections will combine with the direct sound from your speakers, causing an acoustic distortion called comb filtering (or “time smearing”). Comb filtering colors your sound (changes its spectral content), masks details and prevents accurate localization.

What are early reflections in audio?

According to standard definitions, early reflections are sounds that arrive at the listener after being reflected maybe once or twice from parts of listening space, such as walls, ceilings and floor.

Where are early reflection points located?

Where is the 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.

Should my first reflection panels be 2 or 4?

2″ thick panels made from rigid fiberglass or rockwool are the most common product used to treat reflection points, but 4″ panels are a great option when additional bass trapping is desired. When you can see the reflection of the left speaker in the mirror, mark that spot. That’s your first reflection point.

What are first reflections?

Early reflection points or first reflections are terms to describe direct sound which arrives at the listener’s ears before the rest of the reflected sound does. Sound reflects not just off the walls to the left and right, but off the floor, the ceiling and everything in-between.

Why are acoustics bad windows?

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 the 38 percent rule?

THE 38 PERCENT RULE The placement method used here is based on the “38 percent rule” which theorizes that the best listening position is 38 percent into the length of the room, when measured from either the front or rear wall. This offers the best compromise of peaks versus nulls for any given room size.

Should you put reverb on vocals?

Reverb will fill the sound of the vocals out nicely. It will give them more fullness and sustain, and will have a more “natural” sound to them. BUT reverb will also push the vocals back in the mix. It can cause them to lose energy and cohesion, because it overlaps the words and washes them out.

When does the sound of an early reflection come?

According to standard definitions, early reflections are sounds that arrive at the listener after being reflected maybe once or twice from parts of listening space, such as walls, ceilings and floor. They arrive later than the direct sound, often in a range from 5 to 100 milliseconds, but can arrive before the onset of full reverberation.

What are the two groups of early reflections?

Classifying Reflections Reflections can be divided into two groups: early reflected sounds and late reflected sounds. 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.

Why are early reflections important to the brain?

The early reflections give your brain the information about the size of a room, and for the sense of distance of sounds in a room. They have an important role in determining the general character and sound of the room.

Which is the best treatment for early reflection?

One of the most common “generic” acoustic treatment recommendations is to treat the reflection points. Unfortunately properly managing early reflected sounds is actually very complex psychoacoustically.
