Technical Information
  Acoustic Sound Enhancer
 

Echo Shield Panel is designed to highly sound absorptive over a spectrum of frequencies. It is deemed effective in enhancing the acoustic quality of an area by reducing both the Reverberation Time (RT) and overall built-up loudness of any sound in the environment.

In essence, lower RT provides one with better audibility as well as clearer speech intelligibility.
 
Advantages
Fuller, richer musical
Sound. The organist
Would like it.

Disadvantages
Some loss of articulation,
more difficulty
understanding speech.
8.5 s

Highly reflective surfaces lengthen the reverberation time.

2.5 s
Notre Dame. Dramatic for the big pipe organ, but don’t make a speech.

“Muddy”, severe loss of articulation, can’t understand speech.
1.5 to 2.5
seconds
For a general purpose auditorium for both speech and music.
Advantages
Clearer articulation of speech.
Desirable for lecture halls, speech only.

Disadvantages
Loss of richness and fullness,
not a desirable place for music.
1.5 s

Absorbing surfaces shorten the reverberation
time

0 s
 “Dead” sound, difficulty hearing in back, loss of bass in back.

No reverberation gives pure inverse square law behavior.
