What is Reverberation? Part Two (Continued from Part One)

You can say,

  • What on earth is reverberation time?
  • How do I treat it.?
  • In a room with high absorption or with few reflections the sound dies immediately or very quickly allowing us to reply.
  • Well what is the time taken for noise to stop after the noise source has ceased, is it measured in milliseconds”

With a relatively dead room (a room with a short reverberation time) the noise (words) created by the spoken sentence become inaudible relatively quickly, allowing the response to be heard and a further question asked, with relatively ease.

However in a live room (a room with a higher reverberation time) this becomes a much more difficult task to carry out. The sound of the previous word over laps the sound of the next word and the sound of the first sentence over laps the sounds within the second sentence and so on and so forth. This means the examples from above would sound more like. (Where capital words express more clearly heard word)


How do i TREAT it? the time for NOISE to Stop…… You get the idea.

It is like having a conversation in a round, like when you sang nursery songs as a child.

However high reverberation time isn’t always a bad thing, if you are Gregorian monk or in a vocal group, a longer reverberation time is desired as it produces a more appealing and warm sound.

This provides a much desired atmosphere to listen or to record in. Producing music in a dead room for this type of activity would really take away from the atmosphere and kill the mood and ambiance trying to be achieved, as the notes world die very quickly and make the sound appear very flat.

As we all know reverberation itself is a perplexed subject which needs more elaborative, more amplified refinement which we can establish and Institute for your complex issues.

What is Reverberation???

Reverberation is another name for what most people know and understand as echo. The following analogy explains what reverberation is quite concisely without getting overly technical.

If you press the accelerator pedal of a car, the car accelerates to a certain speed. If the road is smooth and level the speed will remain constant. With a constant force on the accelerator, the engine produces enough horse power to overcome frictional and aerodynamic losses and maintain a steady and even speed, or steady state condition. If you take your foot of the off the accelerator, the car will gradually slow, and come to a stop.

Sound within a room acts similarly to this. When a loudspeaker is turned, it emits noise into the room that quickly grows to a certain level. This level is the steady state or equilibrium point at which the sound energy radiated from the loudspeaker is enough to over come loses in the air and at the room boundaries.

A greater sound energy radiated from the loudspeaker will result in a higher equilibrium level, whereas less energy to the loudspeaker will result in a lower equilibrium level. If you push your foot flat to the floor in the car the equilibrium or speed will be much faster, than those Sunday drivers who only slightly depress the accelerator pedal.

When the loudspeaker is turned off, it takes a finite length of time for the sound level in the room to decay to inaudibility. This means there is an exact amount of time from when the loudspeaker is turned off until the sound from the speaker cannot be heard.

For most environments such as conference rooms, classrooms, sports halls, offices and the typical working environment or public space, the longer the time between the noise source stopping and the noise becoming inaudible, the worse the acoustic environment is perceived. This is because a lot of words and noises overlap one an another.
