Ecophon Acoustic Calculator recommendations

General advice and recommenations for the Ecophon Acoustic Calculator.

Take into consideration that...

Increased amount of sound scattering objects e.g. furniture will influence the acoustic parameters.

Increased scattering will normally shorten the reverberation time and increase the speech clarity. Sound strength is generally less affected. 

 

If the calculated reverberation time T20 is too long:

  • Use ceiling absorber with higher sound absorption coefficient
  • Add wall absorbers

If calculated Speech Clarity C50 is too low:

  • Use ceiling absorber with higher sound absorption coefficient
  • Add wall absorbers positioned to remove late sound reflections

If calculated Sound Strength G is too high:

  • Use ceiling absorber with higher sound absorption coefficient and/or increase the total amount of absorption

If calculated Reverberation Time T20 at low frequencies is considered too long:

  • Use thicker ceiling absorber and/or use extra low-frequency absorbers above the suspended ceiling or increase mounting height.

Note: Ecophon recommendations are based on our experience up until today and might be subject to change in the future.
