first, i need a background of acoustic experiments using Coordinate Response Measure (CRM) method.
Second, please answer these three question in acoustical engineering way.
1-Does the percent correct identification of a target speech signal depend on the reverberation time describing the simulated room acoustics in which the signal is heard?
2-Does the percent correct identification depend upon the level of the signal relative to the level of other speech signals that are simultaneously presented to the listener?
3-Is there an interaction between reverberation time and signal to noise ratio such that the effects on performance of one variable depend upon the level of the other variable?
Have a lock to these references.
