I'm interested in collecting human subject data at the LDC. Can you describe the soundbooth's features designed for noise reduction and audio quality within their recording facilities? Also, please list the general types of microphones they have available for data collection.
Navigate to 'catalog.ldc.upenn.edu'. Search the LDC Catalog for 'Human Subjects Collection' using the 'Find keywords in corpus description' field. Click the 'Search' button. From the search results, click the link for 'LDC2013S03 Human Subjects Collection'. On the 'Human Subjects Collection' page, locate the 'Recording Facilities' section. Extract and summarize the soundbooth's noise reduction and audio quality features. Extract and list the general types of microphones available.
Successfully navigate to the 'LDC2013S03 Human Subjects Collection' page. State that the soundbooth has an acoustical seal and drop sweep on the door, a multi-pane window, and two layers of acoustic treatment on walls and ceiling. Mention that audio and control signals are routed via customized wallplates to a rackmounted digital audio workstation outside the soundbooth to minimize noise. List the types of microphones available as: studio, lavalier, headset, and general purpose microphones.
