Hi All,

I'm newbie here and also noob at EASE,so i'm going need help.I was wondering what will be happen if reverberant sound level is higher than the direct sound level interm of dB? is it bad thing?

Thanks

Dear user,

Please let me suggest you some text books and tutorials that might be helpfull in the process:

- EASE 4.3 Tutorial: http://renkus-heinz.com/support/software-support/ease_support/tutorials/tutorials.html

- Fundamental concepts in Acoustical Measurements: http://renkus-heinz.com/easera/fundamentals.html

- Handbook for Sound Engineers (Ballou, Glen)

- Master Handbook of Acoustics (Everest, Alton)

- Architectural Acoustics (Long, Marshall)

Additionally, in EASE 4.3 manual you can find an appendix explaining the calculations performed in the program, in general. The manual can be found at: Program Files/EASE4.3/Easepath/Ease43Manual

Hope this Helps,
Pedro Lima

I would like to add another reference : -
Sound Reinforcement Engineering by Wolfgang Ahnert and Frank Steffen.

There are many observations regarding direct to reverberant ratio in acoustics :- Reverberation Radius and Critical Distance are two meaures that relate strongly to D/R ratio.

I suggest you research the definition of those two terms for a start then check out clarity measures and also the definitions of reverberant energy, reverberation time etc. A simple question you mighty ask yourself is ... Which sound conveys most intelligibility ?? Reverberant sound, which has no defined source nor temporal signatiure save to say it's totally random, or Direct sound - straight from the source. There is value in hearing both direct and reverberant sound - in measure appropriate to the location and the material : - speech, contemporary music, classical music, pipe organ ... etc etc.

Best Regards
P.J.P.
