The EasyMDT (Landsberger at Stupak, in press) is a tool used to measure Modulation Detection Thresholds (MDTs). MDTs are considered a metric of temporal processing. The test is based on Won et al. (2011) and Bacon and Viemeister (1985).
EasyMDT can measure detection of multiple modulation frequencies, however the default and recommended setting is to measure modulation detection only at a modulation frequency of 100Hz. Collecting an MDT is quick (under 3 minutes for 100 Hz), and correlates with CNC words, AzBio Sentences in noise, and consonant identification. |

We are still working on a manual for EasyMDT.
In the meantime it should be as simple as unzipping the file and clicking on EasyMDT.exe |
100 Hz Modulation Detection Thresholds measured with EasyMDT correlated with the recognition of CNC words, AzBio word recognition (+10 dB SNR) and consonant recognition for cochlear implant users. No correlation was detected between 100 Hz MDTs and vowel recognition.
