No Comments With all that is happening throughout the world in general and the economic crisis that is engulfing our nation in particular, this paper has provided me the opportunity to reflect on my ethics.
What are early reflections? When you listen to music in a room, you hear a rich blend of speaker sound and room sound. What you perceive as one sound is actually multiple mashed together: The direct sound coming from the sound source your speakers, or a performer.
Early reflections bouncing off nearby surfaces like the ceiling, floor, walls and reflective furniture like a desk or console. Late reflections, which in the worst case are maniacal echoes, but they eventually merge into what you hear as reverberation pleasant ambience.
Early reflections are the first reflections you hear within about 80 milliseconds of hearing the direct sound from your speakers. They give you important cues about your location in a room relative to the walls, floor and ceiling. Early reflections also give you cues about how big the room is.

To hear those first reflections of the guitarists playing in the performance hall, we need to suppress the first reflections in your playback room.
Early reflections can butcher your soundstage You want the soundstage in your room to faithfully reproduce the soundscape encoded in your media. This means you want to hear spatial cues coming from your speakers — not from your room!
But early reflections from your room can overpower the spatial cues in your media. They throw off your imaging, destroy your soundstage and mask fine details like the sense of depth and width in a recording. This is called auditory masking. When you play back a recording in your room, the recreation of that recording in the x, y and z axis is called the soundstage.
Soundstaging refers to how accurately your playback system reproduces the size, shape and acoustics of a recorded space and the performers in it. A realistic soundstage lets you close your eyes and perceive sound sources between your speakers, with good definition and separation.
For example, if you have two speakers, you can localize sounds that seem to come from distinct locations between the speakers. These are called phantom images or phantom sources. Early reflections in a recorded room top vs reproduction in an ideal playback room bottom.
With a realistic soundstage, the virtual source phantom image in the playback room has the same localization cues as the recorded source. Courtesy of Helmut Oellers at www.
Comb filtering colors your sound changes its spectral contentmasks details and prevents accurate localization. Early reflections start a chain reaction Your hearing system combines the direct sound with early reflections and reverberation, so you perceive a single, blended sound.
In many cases, the direct sound contributes much less to the frequency response at your listening position than the combined reflected sound. Early reflected energy continues to bounce around your room as it decays, turning into late reflections and reverb.
Naturally, the character of those first reflections has a huge influence on your total sound. This means you can shape your sound with just a few acoustic panels at your first reflection points! Why not exploit this?
One goal is to find the right blend of direct vs reflected energy. But first things first: There are two ways to create an RFZ: Splay angle your walls and ceiling so early reflections are deflected away from your listening position.Reflection Paper Guidelines Just as the name implies, the reflection paper is a chance for you to turn inward and reflect upon the presented material.
Your writing is not about “getting it . The format and requirements for the reflection paper are given below. A rubric has also been developed using these criteria and organization for the paper. Your instructor will use this rubric to assess your reflection paper should you decide to take the course for graduate credit.
As you will see in the presentation, reflection formats differ depending upon learning styles. However, for the most part, a reflection paper cites your reactions, feelings and analysis of an experience in addition to an analysis of content.
