Signal Enhancement for the SPID Corpus

In order to cancel the noise introduced by the ambiance simulation, an adaptive filter based noise cancellation algorithm was applied to the recordings of the SPID corpus. Furthermore, a frequency-domain noise and cross-talk suppression was applied. The two time and time-frequency pots below show examples. The enhanced as well as the original signals are available for the entire corpus parts where the ambiance simualtion was used.

Audiometer

Last Wednesday (17.10.2018) we obtained our first audiometer. With this audiometer we are able to conduct both pure-tone audiometry up to 12.5 kHz and basic speech intelligibility tests. The tests may be perfomed for either air/bone conduction or in the free field. Now we can analyze the hearing capabilities of our test subjects, which will help us when performing subjective tests. Special ...
