Hello, is this sentence correct? "When the background noise was lower than the played voice by 10 dB (S/N= +10), the average of the speech intelligibility test was at its maximum value."
Thank you!

Does this mean that decreasing the background noise even further caused intelligibility to fall? This seems an odd result.

Thank you for your reply. The intelligibility doesn't fall but it is at its maximum value.
"When the background noise was lower than the played sound by 10 dB (S/N= +10), the average of the speech intelligibility test was at its maximum value."
If intelligibility is at a maximum at 10 dB, then it should decrease either side, i.e. should decrease if the background noise falls further than 10 dB below the played sound. This is what I was querying. But now it occurs to me that 10 dB may have been the minimum level that you tested?
In any case, as I forgot to mention, the sentence is correct English.
