Reverberation (2)

 

 

Reverberation:

- The sum of audible reflections

- A series of reflections so closely spaced that the ear/brain combination hears them as one continuous sound

- a.k.a. random sound energy, the acoustic ‘character’ of a space

 

 

*All sounds we hear is a combination of direct & reflected/reverberant energy

 

▲ Direct Sound + Early Reflection + Long Reflections = All sounds we hear

Reflection: sound energy that is returned to a space after an encounter with a barrier

 

 

Reverberation ≠ Echo

Echo is a reflection which is completely separated from the direct sound

 

 

Absorption

: The sound energy that is lost in an encounter with a barrier

 

 

All materials exhibit a Reflective/Absorptive nature

: a.k.a. —> Absorption Coefficient

 

 

*In all materials, the Ref./Abs. nature is frequency dependent. The Absorption Coefficient does not reflect this.
